Ofcourse the tflop number is meaningless now it's half of what you said it was.

Not in 16 bit FP calculation it's not lol. And I've literally said multiple times over the last few years that Tflop is not a great metric for absolute performance. Hence the PS5 often outperforms the Xbox Series X despite the latter having 18% more tflops.

I'm guessing you have low intellect and comprehension, but I literally covered that in my tweet.

He's been doing detailed tech breakdowns since the PS4 era, and still the Xbox guys don't get what is wrong with Xbox. More important than the hardware is the ease of development for that hardware. Playstation learnt their lesson from the PS3, but Xbox went opposite with 2 SKUs.

So now yall back to tflops are meaningless but when u thought it was 33tflops u was bragging 😆 🤣 😂

So like i said in the past PRO is equal to RX6800 16 tflop RDNA2 or RTX3070 nothing more nothing less, combain with zen2 cpu. All this hardware is from 2019-2020 with few custom updates. This console is overpriced!

Nah. 6800 is strictly RDNA2 whereas Pro is hybrid. While they are similarly specced, PS5 Pro has additional RDNA3 features, future RDNA (RDNA4) RT tech, custom AI hardware, faster memory bandwidth and a higher clockspeed.

It's PS5 RDNA 1.5 all over again, and reading responses, like a certain fandom never gets tired of being let down or uninformed. There's reasons PS5 often outperforms Xbox Series X despite the latter having 44% more compute than PS5 and being "full RDNA 2", which Digital Foundry did a video on. As I said at the start of the gen, most RDNA2 features Xbox/PC fans claim PS5 is missing, it was unlikely to use as they're Microsoft DirectX RDNA tie in features, and PS5 doesn't use DX but instead its own proprietary custom API called AGC. Why would PlayStation push for Microsoft DirectX RDNA features, when they don't use DirectX? Any AGC API specific graphics features PS5 uses (that Xbox wouldn't have) are not widely publicly advertised, as PlayStation don't need to advertise them the way Microsoft does due to their PC DirectX market. Thus every customisation PS5 has (which Kepler seemingly glosses over or doesn't recognise), from its faster clockspeeds, cache scrubbers, I/O set up, CPU alleviating decompression, DMA controllers and processors, geometry engine etc, will have been specifically designed around AGC or vice versa, NOT DirectX RDNA2 features. PS6 will be no different. There may be DirectX RDNA5 features they do not need or use, but there will inevitably be other unique customisations of their own and for their OWN proprietary API instead, no doubt bolstered by Amethyst custom features from their partnership with AMD. If history is any indicator, PlayStation is right to prioritise their own API and modifications, as these tend to have greater cost to perfomance results for the hardware vs the competition. The RDNA2 DirectX image below is taken directly from AMD's website, and again, PlayStation doesn't use Microsoft's DirectX. #PS6

Path Tracing on PS5 Pro even as a demo and at 30fps, pretty much confirms at least some games will use PT on PS6, which I said months ago but some said I was crazy for suggesting. PC gamers won't want to admit it, but next-gen the gap between console and higher end PC may shrink in terms of real world differences, bolstered by more competent RT and AI upscaling tech in the next-gen consoles. Keep in mind Valve already confirmed what Steam data already showed, that "the steam machine is equal or better than ~70% of what people have at home", and the Steam Machine is reportedly similar in perfomance to the BASE PS5. In regards to PT in F1 on PS5 Pro, I say drop the base resolution further (there's examples of PSSR 2 looking great even at 864p) and give us 40fps or higher. Also, this is a reason the future/RDNA4 RT tech and custom AI hardware in PS5 Pro was noteworthy. The "2-3x" PS5's RT performance Cerny quoted clearly wasn't just PR bluster. Outside of this demo, it's already allowing WAY better RT than PS5 in some games (Cyberpunk, F1, AC Shadows etc), with better image quality and/or perfomance to boot. Such demo's show there's potentially more to extract, especially for quality modes. #PS5Pro #PS6

Metal Gear Solid Delta is poorly optimised on all platforms and it's disingenuous to use it as indicative of typical PS5 Pro advantages. Even in its infancy PS5 Pro's often delivering on Cerny's target of it achieving PS5 30fps mode like fidelity, only at 60fps. Numerous tentpole games this year show sizeable improvements. Battlefield 6 Beta - "Substantially" better IQ and up to 55% better fps than PS5 in performance mode. Assassin's Creed Shadows - Generationally tansformative RTGI/fidelity mode settings, but at 60fps. Kingdom Come Deliverance 2 - Fidelity and graphics settings of PS5's 30fps mode, but at 60fps. Death Stranding 2 - Near locked 60fps with similar IQ and fidelity as PS5's 30fps mode. Monster Hunter Wilds - Far superior image stability and more consistent 60fps vs PS5. As someone who bought a PS5 Pro at launch, I can absolutely say it's been worth it for me, and I'd struggle to go back to the base system. There will always be outliers like MGS Delta, but they don't represent typical improvements PS5 Pro generally brings. Much like PC releases with issues like shader compilation or traversal stutter, or more general bugginess vs console counterparts, it would be unfair to use those things as indicative of PC gaming performance improvements in totality, or to conclude all PC gaming hardware is a scam lol. Context matters. Video compilation. #PS5Pro #PS5 #DigitalFoundry

Digital Foundry says the rumoured leaked specs difference between Xbox Helix and PS6 (~26% CU), which is far less than between Series X and PS5 (44% CU, but PS5 clocks are faster) is unlikely "to get you a whole lot" and it's "basically not that meaningful". Oliver adds "especially if you're looking at an unsubsidised box on one end, subsidised box on the other end, there could be a substantial price price premium you're paying for that performance." "Because the new Xbox Magnus die is also over 400mm squared, even though I think it is a dual die design, that is a considerably large die for a console. Whereas PS6 seems to be a die around PS5 Pro size, as it's a very svelte die that's monolithic, so that should be cheaper to produce just by its nature as well" Considering #PS5 is also launching AFTER #Xbox Helix, and is likely to come with more mature or advanced Project Amethyst features or customisations, and Helix might not have tenrpole Xbox exclusives either, next-gen could be one where the new Xbox hardware is considerably worse value proposition vs PlayStation hardware, more so than all prior gens.

NEW PS5 Pro CFI-7121 Experiment: The Holy Grail of Soft 11.40? Offline tests on the PS5 Pro confirm: Disc Drive security is tightened (delayed locking after key verification failure), but the console’s behavior is UNUSUAL—and that's the key! 📌 **Crucial Finding:** It doesn't matter if the drive is from 2023 or the latest 2025 revision—the console behaves the exact same way! The issue clearly resides in the **PS5 Pro Software (Soft 11.40)**, not the drive hardware itself. The new system detects and preliminarily initializes an unpaired drive, which was previously impossible without the correct key! 🔥 **THIS COULD BE THE "HOLY GRAIL" OF THE CONSOLE WORLD!** 🔥 The fact that Soft 11.40 shows this "flexibility" in drive communication suggests **many more possibilities** are hidden in the code, perhaps loopholes for: 1. **Offline Drive Activation/Pairing.** 2. **Activation of other "interesting things"** (e.g., debug/service features). If a pairing bypass is possible, all signs point to it being on **this specific software version**!

This is the closest Game we have to compare to GTA VI in terms of Open-World Gameplay. This Matrix: Awakens footage was recorded on Xbox Series X and as you can see the FPS is struggling to stay above 30FPS. The resolution also takes a big hit when you start moving the camera too fast because of so much processing happening at the same time. Considering GTA 6 has probably 10X times the mechanics of NPCs behavior going on and physics that are miles ahead of this game, it's safe to say that a performance mode is going to be near impossible in a PS5/Xbox Series X and S Version. Perhaps when PS5 Pro launches we will get a 60FPS mode, but things are looking rough right now. Let's see how well Rockstar Games manages to optimize their next GTA For more in-depth insights, updates, and discussions on the gaming and tech universe, join me on this exciting journey.

The #GTA 3 port to the Sega #Dreamcast has been progressing at an incredible pace. It's been amazing to see the whole DC community come together to tag-team this "impossible" project... Here it is running on a stock DC, no longer requiring the 32MB RAM hardware modification, only a few weeks into development. Since I finally got the time to sit down, build the codebase, and look into some of what I think is the critical path for performance, let's talk about some technical shit, and some of the future steps I think can be taken to further improve performance. First of all, I want everyone to take note that this is NOT a port of the PS2 version. This is a port of the PC version, which has extra content, increased draw distance, improved textures, and other things that have actually increased the challenge here... Whether the DC version will ultimately have these additions or not will remain to be seen, but we're running into plenty of shit that the PS2 didn't have to worry about (like these big-ass PC replay saves won't fit onto a Visual Memory Unit!) Secondly, lets talk about what is and isn't currently optimized, because it's absolutely vital that the DC's hardware is fully utilized here for the sake of performance and achieving a competitive polygon count. Unlike with modern devices, where the whole graphics pipeline is handled by the GPU, both the PS2 and Dreamcast were responsible for transforming and doing lighting calculations for each vertex BEFORE they got submitted to the GPU. The PS2 had a vector coprocessor to do this, while the Dreamcast had a few extremely important SIMD and fast math assembly instructions on its CPU to do these computations. Up until literally just a few hours ago (not shown in this footage), the Dreamcast's SH4 was doing 100% of these operations in slow-ass plain C and C++ code, which is absolutely sub-optimal and is immediately bogging down its CPU with just transforming vertices, bottlenecking the entire graphics pipeline on the fist T&L stage, and also leaving less CPU time for handling other gameplay logic... this is going to absolutely have to be addressed (and already has begun to be). Another issue that is crippling performance here is the fact that the models are all using individual triangles rather than triangle strips, which the Dreamcast's PVR GPU was designed to handle better... Converting these models to use strips rather than individual triangles will result in MANY different gainz for the DC, as you're going from 3N to N+2 vertices per triangle. Converting the models to triangle strips will 1) reduce load times, since model assets will be smaller 2) reduce the amount of video memory required to hold these vertices on the GPU 3) reduce the amount of shit that must be transferred from the CPU to the GPU and 4) give us back a bunch of CPU time, since the SH4 will be less bogged down transforming redundant vertices! TL;DR: This is still EXTREMELY suboptimal in terms of fully utilizing the graphical potential of the Dreamcast. There is going to be a LOT that can be done still to both improve performance and polygon counts, so stay tuned! FINALLY: Mad respect and love to Stefanos Kornilios Mitsis Poiitidis, for doing an amazing job leading this project, and to Frogbull , Esppiral, and everyone else who is helping us stick it to the PS2 by making this happen! #gamedev #retrogaming #cplusplus

So, a lot of you have been talking about Wuthering Waves' optimization. Let me explain. 5700G (16 MB L3 Cache) + RX 9060 XT (FSR Quality) vs 5800X3D (96 MB 3D V-Cache) + RTX 5060 Ti (DLSS Quality) Note: I even increased the graphics settings on the 5060 Ti to show the difference. Explanation: Both GPUs deliver similar performance overall, but you'll notice higher FPS on the right side. Why? The Ryzen 7 5800X3D's 96 MB 3D V-Cache significantly improves performance in Wuthering Waves, especially 1% lows and overall frame consistency. In my testing, the performance improvement was around 40% compared to the 5700G. One reason is that Wuthering Waves is very CPU-sensitive, particularly in open-world areas. There are also optimization issues that Kuro Games still needs to address. I'm not trying to downplay anyone's PC. I'm simply pointing out that Wuthering Waves benefits a lot from CPUs with larger L3 cache, similar to games like Crimson Desert, STALKER 2, and Black Myth: Wukong. PS5 Performance Kuro Games still needs to improve the PS5 and PS5 Pro versions. Even some demanding games perform better on those consoles, so there's definitely room for optimization. I hope this helps! If you have any questions or want the best settings for your PC, feel free to ask. #WutheringWaves #Gacha

Jensen Huang just looked at every tech giant building custom silicon. And laughed. Every major player is burning billions to escape the Nvidia tax. Google is building TPUs. Amazon is building Trainium. Meta is building MTIA. The logic makes sense on a spreadsheet. Design a chip perfectly tailored to your workload. Cut out the middleman. Own the stack. But the spreadsheet assumes the middleman is standing still. Huang: “Look at the number of ASICs that have been canceled… It’s not sensible, actually.” He is not questioning their engineering. He is questioning their math. Custom silicon takes years. Every design choice is a bet on a target that exists today. And Nvidia does not let today exist for long. Huang: “Because of our scale, our velocity, we’re the only company in the world that’s cranking it out every single year.” That is the real weapon. Not the chip. The clock. Nvidia stopped selling performance. They started selling time. By the time a custom ASIC tapes out, Nvidia has already shipped the next generation. The chip arrives obsolete. Not because it failed. Because it was built for a world that no longer exists. The graveyard of custom silicon is not filled with bad engineers. It is filled with slow ones. You cannot aim a three-year development cycle at a one-year moving target. Every company building custom silicon thinks they are building an escape route. They are building a time capsule.

Some millennials have been working for 20 years and are still confused by corporate 😂 For those who are still in the dark let me fill you in. Your performance doesn't matter. Your performance review doesn't matter. Your compensation has been set by a budget committee a year ago. You are not "overachieving" anything. Management has a fixed pool of money to pay the people they manage so they can give them raises less than inflation. If they give you more money, they have to give someone else less money. It's a zero-sum game. Managers actually have a larger pool of money to hire new employees because corporations recognize that new hires need to be incentivized to come over. They won't just leave their company for the same money. If you've been at the same company for 5 years you are underpaid. If you've been at the same company for 10 years you are paid less than a new hire at a competitor. Loyalty doesn't matter because there is no reason for a company to voluntarily pay you more money. Corporations already know that over 95% of employees will not go anywhere and will take whatever they get. Even if that's nothing. There's no reason to pay everybody more money when only a tiny percentage of workers will leave. Even if you leave... (remember over 95% of employees will not) ... the corporation will distribute the work you were doing among all your coworkers. And they will take on the extra work. And they will stay. For nothing. Because in addition to a salary, what an employee wants is to not have to look for a new job. That's all the want. They don't want to move anywhere. And companies know it, and they will take advantage of that. Now you know! You're welcome.

They won't just leave their company for the same money. If you've been at the same company for 5 years you are underpaid. If you've been at the same company for 10 years you are paid less than a new hire at a competitor. Loyalty doesn't matter because there is no reason for a company to voluntarily pay you more money. Corporations already know that over 95% of employees will not go anywhere and will take whatever they get. Even if that's nothing. There's no reason to pay everybody more money when only a tiny percentage of workers will leave. Even if you leave... (remember over 95% of employees will not) ... the corporation will distribute the work you were doing among all your coworkers. And they will take on the extra work. And they will stay. For nothing. Because in addition to a salary, what an employee wants is to not have to look for a new job. That's all the want. They don't want to move anywhere. And companies know it, and they will take advantage of that. Now you know! You're welcome.

ELON MUSK: We believe the AI5 chip will be roughly comparable performance to an NVIDIA Blackwell, and at much less than 10% of the cost Transcription: I'm super hardcore on chips right now as you may be able to tell. I have chips on the brain. I dream about chips, Literally! Because in order to have a functional robot, you have to have a great AI chip. And it needs to be an inexpensive chip and it needs to be very power efficient So we think we believe the AI5 chip will be probably about a third of the power of say something like a Blackwell, an NVIDIA Blackwell, which is a great chip, for roughly comparable performance. And much less than 10% of the cost. This is a chip that is very much optimized for the Tesla AI software stack. So it's not meant to be a general purpose chip, it's meant to be an amazing chip for the Tesla AI software And I mean a couple of things that I think make... like how is Tesla able to achieve such an improvement? I think it is because we are specialized. We're not trying to... you know, NVIDIA has to serve the superset of all past and future customers. So all of their requirements, all of the software that they've written has to work, which is a very difficult problem. Whereas we just need to make it work for our software. And so we're able to simplify the chip dramatically And then we also, I think we're unique in this, but like we have an integer-based system. And integer operations are fundamentally more efficient than floating point operations. So we can do floating point, but the vast majority of our inference is done in integer. Which is, if you're familiar with sort of logic gates, the simplicity of integer... it's integer is much more power efficient, much more silicon efficient, but you have to, you actually have to train for integer inference, which everyone else is training for floating point. That's kind of like a niche technical detail, but it's actually very important. So, yeah, this is going to be a great chip So this chip will be made in basically in four places: TSMC Taiwan, Samsung Korea, TSMC Arizona, and TSMC Texas. And we already know what improvements to make for AI6. So I'm hopeful that we can within less than a year of AI5 starting production, we can actually transition in the same fab to AI6 and double all of the performance metrics

Horizon: Steel Frontiers announcement video! 👀 MMORPG set in Horizon's world, coming to iOS/Android and playable on PC. Actually looks fantastic! 🔥 +Developed by NCSoft in collaboration with Guerrilla. +Designed specifically for mobile +Play with countless other players in large-scale raids and battles against mechanical beasts, or compete with other rival tribes for resources +Features custom character creator +New combat mechanics +Takes place in a region called the Deathlands, inspired by Arizona and New Mexico To clarify, the game is not on Steam, and can only be played through the "PURPLE" platform, a PC gaming service by NCSoft games. No Steam version has yet been announced. Either way, PS5 being left out is pretty funny, but PlayStation/Sony have been signalling an additional push into mobile for years now. Possibly a large part of the wider consumers they've talked about targeting. #HorizonSteelFrontiers

Praydog’s UEVR Public Beta Is Now Available! Go to or to get started! If you can, donate to Praydog's work here (he's spent thousands of hours doing the impossible). The monumental day is finally here. Praydog has perhaps created the most ambitious modding project that’s ever been attempted Because UEVR is so massive in scope (there’s over 11,000+ UE games on Steam alone and many times that shared other places like it’s hard to streamline this process so that the average “tech-illiterate” can always have a perfect working experience for every obscure game they might want to play. We’re gonna have a LOT of people asking questions (and the same questions over and over again) so please be kind and patient and point people to the FAQ, etc. We are working on bringing game profiles directly to RaiPal’s game launcher so you can just hit play and the best profile auto installs, but unfortunately that’s not all setup yet and we’ll even need your help to make more of the profiles and fixes for certain games. Please be patient, help steer others to the correct channels in ⁠#ue-supported-games Discord channel , help others to set correct expectations (the sky is the limit for what’s possible with UEVR, but some games might not be super playable at the moment and will need some custom code written, etc.) Enjoy!!

✨ I've been using #Unity3D for 12 years. ✨ I'm using Blender's GeoNodes for a procedural mesh that's realtime-animated with a custom shader in Unity. ---(reminiscing, reflection follows)-- At some point, you realize it's 'all' states, relationships, and data/information. What is, isn't, and how they relate, subject to laws, principles. 🌌 Define some latent space -> atomics, data -> simulation/form -> information.

Ghost of Yotei finished. My most anticipated game of the year and it definitely delivered. Visually it's a work of art with excellent combat and exploration. However, I did have some gripes. While I love the exploration, the side content itself gets a bit repetitive by the end (looking at the parkour). Also don't think the story was quite as good as GoT. Atsu is a beast and a good protagonist but Jin's storyline and character development was a little better overall. The story doesn't reach the same highs and the first ending was far better. It has its moments but overall didn't quite land for me. Overall though, definitely one of the top games of 2025. Combat and visuals are among the best in the genre. Stealth and parkour could've used bigger improvements considering how much they're used, but still good. Side quests and Mythic Tales are much improved and the overall presentation is excellent. It's more Tsushima, with a bigger arsenal, a beautiful new open world, and a new storyline to get invested in. Definitely going to end up on my GOTY list and I'm excited to work on the platinum! Final Score: 8.5/10 Platform: PS5 Pro Playtime: 45 hours #GhostofYotei #PS5

Great question! 🤔 How do you simulate *multiple* layers of glass/refraction in video games? In the last breakdown, I discussed how to create a glass shader in Unity URP. In essence, we were taking the render of the scene from the camera without any transparent objects. This is available in URP as the global _CameraOpaqueTexture. This is good enough for most use-cases, and more or less the classic way of doing it. 🔍 What is _CameraOpaqueTexture? As the name implies, there are no transparent objects rendered into this texture, so it's not possible by default to have something like a transparent-type ocean material/shader rendered through a refractive glass shader (which samples and distorts this texture to render on its surface, as if it's transparent). ⚠️ Why it’s tricky: It's much easier to sort without much further setup if you don't have refraction, and only a transparent material, because in that case you're not simulating the transparency yourself via sampling the rendered scene texture. But for refraction, it's required-- unless you want to go down the ray/path tracing route. You could simulate accurate, real dispersion... and that's about as expensive as it sounds, and it requires a rework of your entire rendering. --> 🚫 It's not a viable suggestion to offer. 📚 There are well-known terms regarding transparency sorting you can search up, but as you've specifically asked for refractive boxes, I'll discuss briefly about that. 🧱 Simulating layers of refraction: For this kind of rendering, you need some way to render the backfaces before rendering the front. And the backfaces that are rendered may contain whatever data you'd like for additional processing in the layer front-facing mesh render. 🧪 Examples: You could render the back face as a glass shader of its own, as an intermediate step after _CameraOpaqueTexture. Then you sample this texture instead and you end up with multi-layered refraction, "just like that". You can also render the back normals only, via a fully opaque shader, and use that to manually account for that during the front render. You could even bake in data needed for thickness in realtime. 🛠️ Without making it complicated for yourself, the most straightforward method is via render textures, and you can easily set some fractional resolution. Cameras in Unity have an open slot for target textures to render to. You can use custom render textures to process _SelfTexture2D. ⏱️ It's great to do low-resolution processing for more complex tasks, like blurring and caustics. You can get massive performance boosts, considering the square law and number of pixels/fragments that need calculations (quadratic scaling). 🚧 I've not fully exploited the possibilities myself, but research/development with PRISM is ongoing!

SURPRIIIIIIISE!!! The beta release of our Grand Theft Auto Vice City port to the Sega Dreamcast is finally here! Here's an actual hardware capture of raising some hell in the beautiful streets of Miami taken straight from my DC to celebrate! We've now added graphics settings for 2xFSAA to give it a less jagged, more smooth look and have added a video mode for rendering to a 24bpp framebuffer, which adds extra depth and vividness to the colors! While we still have plenty of work to do regarding features, assets, and performance, I am extremely proud of our team after what we've accomplished within just a few short months with this port that, for the last two decades, was considered literally impossible for the console to handle. It has been an absolute honor and privilege to work beside you crazy and talented bastards! I also want to thank the Sega Dreamcast and Grand Theft Auto communities for rallying around this cause and coming together to help us test and debug this release along with the previous GTA3 release over the last several months. Your support and diligent work has been vital for ensuring that the games have been fully playable on the DC, and your constant support and feedback has been an inspiration to the team. We couldn't have done it without you! For instructions on how to convert your (LEGALLY EFFING PURCHASED) PC versions of GTAVC into a image which can be played on the DC, the instructions can be found here: PS: No, this is not an April Fool's joke, but we're going to love everyone thinking it is! Guess you're gonna have to try it to find out!🤣
