Still a work in progress. Sculpted and textured in ZBrush. Next step, rendering in Blender!

Progress on the Sonic Frontiers multiplayer mod! I'm rendering on 2 panes now, though obviously there's still a lot to fix.

First look at volumetric plume trails in Kitten Space Agency. This is an early work in progress using a novel rendering system where each trail is fully volumetric and built from connected curve segments, with no particles used.

Making a ton of progress with the 3D/VR Port of Stardew Valley. Voxel/Cross-Plane rendering which gives off a kind of "fake" 3D effect. Point selecting on wrist HUD, seamlessly switch between 2D/3D/VR, Characters/monsters now face you + a lot more #stardew #vr #virtualreality

Short demo of the SDF tools so far. Everything is non-destructive🙌 There are still some rendering aspects that need to be updated before I can move on to the UI though. Slow but steady progress👌 Releasing a prototype before the summer hopefully🙏 #b3d #blender #blender3d

I still can't believe we are building this quality game that runs on my Mac. Day 18 of building my own GTA 6 with a loop of AI agents. Today's progress: - the shadows and car reflections look real now, not like a cheap game anymore. - spent over a day on performance, so it runs smooth. By the way this is a Mac, not a gaming PC, so a lot of the rendering and lighting is not gonna be the same as the NVIDIA GPU. We are almost there. right now i'm debugging the driving so it feels smooth. quick question, what do you all want to see in the demo?

Today we're taking a very early look at the progress being made on the Sega Dreamcast's very own port of Runescape Classic! If you weren't already aware of the work that developer, Lobotomy, has been doing, here's some footage captured from an emulator of some online play! It's still extremely early, and as with every ambitious port in the beginning, it still requires the 32MB RAM upgrade, has no audio, and runs like ass... So basically standard procedure! He's currently using our SDL2 back-end with software rendering, which explains the low framerate. Eventually it will move to HW accelerated graphics using the DC's PowerVR GPU, so the current low FPS is to be expected until that time. What IS a big deal is that even in this early stage, it's already able to connect to the online servers for cross-play and is fully playable with the mouse and keyboard! Stay tuned for future updates as Lobotomy continues his work!

FINALLY time for the big announcement everyone has been begging and waiting for... Here's a VERY EARLY direct hardware capture of Mario Kart 64... RUNNING ON THE SEGA DREAMCAST, of course! This game was literally just BARELY decompiled the other day, with a codebase that is still quite married to the Nintendo 64 platform... but this didn't stop jnmartin: the dark coding wizard who brought us a dynamically lit and bump mapped Doom 64 and Wipeout running at >100FPS on the DC! What you're seeing is the insane progress made by one man in just 3 weeks. As is to be expected, there are all kinds of visual glitches and rendering artifacts, the framerate is all over the place, and there's no audio yet... which is totally typical of any ambitious DC port in the early stages. The DC build wouldn't even get past the menu screen without crashing or running out of RAM until just a few DAYS ago, yet here it is, every level playable WITH multiplayer support already on the DC! Even in this early stage, you can already see the game benefiting from the PVR's crisp 480p output... Each players' little viewport window in 4 player mode is the same resolution as the entire screen was on the N64! Stay tuned for future updates as jnmartin continues his work to bring this classic to our little white box of Dreams!

During DLSS 5 Hands-On Video, YouTube creator Hot Hardware asked Nvidia employees this question about the computational cost of DLSS 5 when you move around in the game and it really caught my eye on how they hesitated on showing any DLSS 5 footage during motion. Every time that he moved the character, he would turn off DLSS 5 first then move to a different in-game location and then turn it on, or if DLSS 5 was turned on the movement was very slow and controlled. I know this is still work in progress, but it really begs the question "why wouldn't they show any this?" or "why show DLSS 5 this early?" I tried freezing some shots when another character is in motion to check if there are any artifacts when DLSS 5 is turned on. As suspected, I did come across some artifacts with UI elements, character popping out of the UI element and ghosting/artifacts behind the character. Its still not the best way to judge these small details that you can clearly see if a footage is recorded in-game, but then again its not like Nvidia provided any of them during DLSS 5 marketing campaign. Whenever this is still going to be present by the time DLSS 5 launches remains to be seen, however as of right now it doesn't look like it will handle fast-paced motion quite well and I don't know how well this "controlled AI-generated" rendering will scale to weaker GPUs in the RTX 50 series

🇺🇸 THOMAS JEFFERSON WARNED US, CAREER POLITICIANS WERE NEVER THE PLAN David Friedberg from The All in Pod pulled out two Thomas Jefferson quotes that hit harder than ever, framing the fight between public service and career power as America’s oldest moral test. He argued the Founders never meant for politics to be a lifelong hustle... it was supposed to be a duty, not a paycheck: "There are two quotes from Thomas Jefferson. I’ll just read because I think it’s actually very important. He said in a letter in 1788, ‘I apprehend that the total abandonment of the principle of rotation in the elected offices will end in abuse.’ And then he also later said in 1809, ‘Nature intended me for the tranquil pursuits of science, which is what he was into by rendering them my supreme delight. The enormity of the times in which I have lived have forced me to take a part in resisting them and to commit myself on the boisterous ocean of political passions.’" Friedberg said Jefferson’s warning was prophetic, the Founders wanted free people chasing science, trade, and progress, not politicians hoarding wealth and power. He called today’s career officials the opposite of Jefferson’s vision, contrasting them with business leaders like David Sacks, Sec. Bessent, and Administrator Loeffler, who “already made their money” but chose to serve out of patriotism. His message: the real test isn’t wealth, it’s motive. Are they serving the nation or milking it? Source: The All-In Podcast

Ouroboros "short" Leios Protoyping simulation & visualisation work in progress demonstrated by Duncan Coutts. Full P2P network running Leios Visualisation. You can see 100 different nodes and messages flowing between them all, with representation of Input Blocks (Top left, Endorsement Blocks (20 seconds In these increment), Votes (20 seconds in these increment as the pipeline hits a vote stage) You can see the votes continue to burst at roughly 20 seconds, input blocks also increase, the smoothness of message flows to reduce these bursts is something Duncan details they are working on to improve as-well as resource usage. Input Blocks (IB) - These blocks contain the raw transaction data submitted by users to the blockchain. Endorsement Blocks (EB) - These blocks reference multiple Input Blocks and are used by nodes to validate and vote on the readiness of transactions for inclusion in the blockchain. Votes- Nodes cast votes to achieve consensus on the state of the ledger, enhancing the speed of transaction finality. I believe this is completely off-chain so does not incur transaction costs (Someone keep me honest please) Keep an eye on the diffusion latency chart, as Duncan mentions this is very important, this refers more to time taken for propagation of information across the network I believe. This was an extract from a larger demonstration, really exciting, massive credit to the team working on this. It's going to be extremely impactful to Cardano and I will share as much as I can about it, I really like seeing these visualisations especially during a prototyping stage. What I find interesting is that the visualisation vote count is so much it slows down the browser rendering. Great work! web3innovationnerds & Duncan Coutts what a demonstration that was., keep them coming!

** Sega Genesis 3D Engine Update 8 ** Significant improvements all round as you can see and hear from the last update !! Foremost - A huge thanks to Toni Gálvez - Megastyle - BG. who has joined the project to create a bit of 16bit low poly magic. Toni's an Amiga fan but also crazy about game dev in general, he's worked on GBC, GBA, PC, MD, PSP, C64, CPC, MSX... and others. Gaming titles include War Times, Metal Gear, Rocketman, Tintin & Asterix to name a few. He's provided the great new ship model you see on screen - new striped buildings, all the backgrounds / palettes etc. There's a lot of models he's given me which need to be added, also he will be planning a lot of the level design. Very happy to have him help me turn this into something more than a tech demo as I have my hands tied pushing the MD as far as it can go haha - there is no cpu cycle to be spared. Also many thanks to my good friend CYBERDEOUS - Crouzet Laurent for the Music for this showing , I wanted to have the music load occurring so we have a realistic benchmark for performance and he was only too obliging. If you're into MD chiptunes check him out !! Since last update : New player model , substantially more detailed than the Arwing. Last update had a 23 triangle Arwing , this update has a 39 triangle custom model from Toni. We had several to choose from , others will be used for enemies . 3D Buffer size increased 25% to 256x160. This was quite tricky as I'm close to the DMA limit even with an extended vblank . Spent a few days thinking of how to do this as like anything retro every solution has a drawback, finally got a workable solution. It makes a big difference to have a bit more vertical height . Z Rotation added ( the screen tilting left to right ) , small hit to vertex transform on cpu thanks to look up tables doing the heavy lifting, saving 4 multiplies per vertex. Multiple speed ups in rendering code. Onscreen paths with no range checking used until Z is close enough to cause clipping , partial onscreen drawing pathes that need to check boundaries, quad rendering completely rewritten - was very very painfull to get right . I found out the hard way that things are great when they are not rotating in the Z axis haha . Partial buffer draw optimisations - which have helped with the massive dma load , sending up to a 20kb buffer in a single frame needs a lot of optimisation. Min / Max tile lines are analysed and only sent if dirtied , reducing most buffer swaps substantially. Still some issues to sort out , at times you can see the flicker near top of screen when frames are near full height . I need to optimise that a bit. Due to the onscreen buffer system a full Sprite background had to be implemented almost Neo Geo style. This flips the usual MD rendering system on its head as it uses both foreground and background layers for a foreground 3d plane and sprites for the background. This presents a few issues, one is to get a tilt effect on the background by using narrow sprites (16x32) we run out of sprites when trying to cover the screen. Thankfully the MD is not limited to 80 sprites, to fix this a 114 sprite multiplexor is used to draw the background, its completely made up of 16x32 sprites ! Why do things this way ? speed . Its the interleaved foreground/background layers that allow a double buffered ram system writing to write to vram using dma in a completely linear fashion - virtually no tile translation needed. The negative is you have no planes for the background, that's where the sprites come in . Thanks to H40 mode we still have a few sprites we can use for effects in the forground also . Thankfully we can implement a fairly good tilt still for the background using sprites, in future updates this will be able to move horizontally also and a bit of vertical movement. XGM1 music driver in use to simulate music cpu load, XGM2 unfortunately with the massive DMA needed to shift the 3d buffers would slow down at times rendering it unusable, XGM1 plays at full speed - albiet with a bit more of a cpu hit. Together with the sprite multiplexor and the music driver active theres a 10 % hit to cpu so I've had to play around with draw distances / object heights and other optimisations to offset that. Not to mention the larger buffer takes more cpu to fill also. Everything is placeholder so will be changed with proper stage design. We are averaging 20 FPS in the current video, I'll push for more as always !! Progress continues on my other projects , updates soon on those - retirement can't come quick enough . #SGDK #SegaGenesis #SegaMegadrive

RESTLESS LEG SYNDROME EPIDEMIC! The recent enforcement actions by the U.S. Food and Drug Administration represent a significant and welcome step toward greater transparency and patient safety in direct-to-consumer pharmaceutical advertising. These measures require drug manufacturers to incorporate comprehensive safety warnings, contraindications, and precautions directly into their advertisements, eliminating the previous reliance on abbreviated or obscured disclosures. While not an explicit ban, the practical implications are profound: The 30- to 60-second formats will become untenable for conveying such detailed information without compromising clarity or compliance. This shift is unequivocally positive, prioritizing public health over commercial interests and addressing long-standing concerns about misleading promotions. Critics may suggest extending ad lengths—such as to six minutes—to accommodate the required disclosures. However, this approach is fundamentally unfeasible and unlikely to sustain DTC advertising in any meaningful way. Longer formats would dramatically increase production and airtime costs, potentially rendering them economically prohibitive for broadcasters and advertisers alike. Moreover, viewer engagement would plummet; research indicates that audience attention spans for commercials are already limited, with most consumers tuning out or switching channels after mere seconds. In a fragmented media landscape dominated by streaming and on-demand content, six-minute ads would disrupt programming flow, alienate viewers, and fail to achieve the intended marketing impact. Ultimately, whether short or extended, these requirements will discourage DTC campaigns, fostering a healthier ecosystem where medical decisions are driven by evidence rather than advertising. The harms perpetuated by unchecked DTC advertising provide compelling justification for this reform. Empirical studies demonstrate that such promotions overemphasize benefits while minimizing risks, leading to overprescription and inappropriate drug use. For instance, exposure to DTC ads has been linked to reduced medication adherence when conflicting safety information emerges, as well as distorted patient-physician interactions. Quantitatively, a 10% increase in DTC spending correlates with a 1% to 2.3% rise in overall drug expenditures, according to the Congressional Budget Office, contributing to elevated healthcare costs without commensurate clinical benefits. Furthermore, drugs with higher DTC promotional budgets often exhibit lower added clinical value, exacerbating inefficiencies in healthcare delivery. By curbing these practices, the new guidelines promise to mitigate unnecessary suffering, lower costs, and enhance outcomes—benefits that far outweigh any transitional challenges. The economic ramifications for traditional media companies underscore the scale of this transformation. In 2024, pharmaceutical firms invested approximately $10.8 billion to $14 billion in DTC advertising across all channels, with national television alone accounting for over $5 billion. Prescription drug brands represented 11.6% of total national linear TV ad spend that year, a critical revenue stream for legacy broadcasters. Should these guidelines precipitate a substantial reduction in DTC campaigns—as anticipated—media outlets could face an annual revenue shortfall of several billion dollars, potentially up to $7 billion from television alone. These FDA actions mark a pivotal advancement in safeguarding public health, and I strongly endorse them. By rendering DTC advertising impractical—regardless of format length—they pave the way for a more informed, equitable healthcare system. This is progress worth celebrating. The 🔮 is never wrong.

RESTLESS LEG SYNDROME EPIDEMIC! The recent enforcement actions by the U.S. Food and Drug Administration represent a significant and welcome step toward greater transparency and patient safety in direct-to-consumer pharmaceutical advertising. These measures require drug manufacturers to incorporate comprehensive safety warnings, contraindications, and precautions directly into their advertisements, eliminating the previous reliance on abbreviated or obscured disclosures. While not an explicit ban, the practical implications are profound: The 30- to 60-second formats will become untenable for conveying such detailed information without compromising clarity or compliance. This shift is unequivocally positive, prioritizing public health over commercial interests and addressing long-standing concerns about misleading promotions. Critics may suggest extending ad lengths—such as to six minutes—to accommodate the required disclosures. However, this approach is fundamentally unfeasible and unlikely to sustain DTC advertising in any meaningful way.
