More internal optimizations on my #Dreamcast and #Gamecube game engine: • 2D Perlin noise generation is now 67% faster (59 cycles per sample) • 3D Perlin noise generation is now 40% faster (97 cycles per sample) • Further optimized worst-case heap allocations, bringing the total improvement to 40x since... before my last post (yeah, allocations were that inefficient for a while) Perlin noise generation is one of the game's most resource-intensive functions. Since the Dreamcast doesn't support conventional SIMD, I optimized Perlin noise using purely scalar code. The Dreamcast's SIMD capabilities are mainly tailored for graphics, with matrix-vector multiplication and dot product being the only SIMD instructions available. These optimizations are invisible to the player, so in the meantime, here's an interesting spot I discovered while testing the game on the Dreamcast. #retrogaming #indiegamedevshow more

How exactly is the "ambient occlusion" handled in this engine? does it intelligently swap out textures based on surrounding blocks? it's so clean it almost looks per pixel but I imagine you don't have the overhead to do that in software, right?

Ambient occlusion is handled with vertex colors.

This is the Dreamcast version. Here’s how it looks on the GameCube:

2 questions Do you plan to add like greedy meshing or smth if u havent And are you changing the color of the sides of grass (Im also making a mc clone in turbowarp :3)

I love your work. Little by little you are pushing the Dreamcast capabilities to the limit. How many polygons do you reach in this post?

130,000 vertices, right up to the VRAM limit.

Is this video on DC or GC? Either way, it's impressive.

In my #Minecraft-like engine, mountains with this level of scale and detail were once out of reach on the #Dreamcast. But with recent optimizations, they're now a reality: • The renderer is now 19% faster, achieving near-peak efficiency at 30 cycles per vertex (up to 6.67 million vertices per second) • Aggressive occlusion culling reduces polygon counts by over 50% • Lighting and meshing is now 73% faster • Terrain generation is now 6% faster • Optimized frustum culling #indiegamedev #gamedev #Gamecube

So I updated "Water" ! The sim is running in a single CPU thread. It should work faster now, rendering optimized & WebAssembly SIMD support! But seems like the speedup with wasm is only limited because of the heavily scattered memory access pattern 😇

The #Gamecube game engine now boasts a render distance of 13 chunks, surpassing the render distance of Minecraft on the Switch (docked). Cloud shadows now distort as they move and soften during sunrise and sunset. #retrogaming #indiegamedev #gamedev #Dreamcast

Dreamcast is so powerful... It's not just an image on the screen. You can interact with the in-game PC with the Dreamcast mouse and keyboard. (I won't copy Win95 for the final look, want to design my own fake OS :D)

Added a simple Perlin noise wave function to the mud to add some extra movement! Combining this with the snow system and plant interaction system you can get some very dynamic environments! #RobloxDev

I have something very special to share today! This is a hardware capture of maximqad's port of the Xash3D engine--which is compatible with the Half-Life engine--running on the Sega Dreamcast... ONLINE! Keep in mind this is EXTREMELY early in the days of the port, with no DC-specific graphics optimizations or hardware accelerated math routines yet, so performance still has a lot of room to drastically improve. Audio was literally just barely moved to the SPU for the first time just the other day too, so this is still all very incredibly new... ...but here it is! The engine that wouldn't even run without being on an emulator that also needed to emulate the extended 32MB RAM modification... now running on a stock Sega Dreamcast with online multiplayer connectivity and mouse and keyboard support! Fantastic work from maximqad! I really believe as this engine matures, it will be an incredibly powerful tool for Dreamcast developers and will potentially bring a lot of new software to the platform in the form of Half-Life engine mods!

I ported my #Gamecube game engine to PC, and even in its unoptimized state, it runs at 60 FPS with a minimum render distance of 64 chunks on my laptop -- double the maximum render distance of Minecraft: Java Edition. Powerful hardware won't be necessary for the game to run smoothly at long render distances. The PC port will streamline the debugging process, allowing for faster improvements across all platforms, including the Gamecube and #Dreamcast, and Wii. #indiegamedev #gamedev

Every day is a fantastic day to be playing Counterstrike... ON THE SEGA DREAMCAST! What you are seeing is a couple minutes of video featuring online play captured directly from the real hardware! This monumental feat of engineering is to be credited to developer, maximqad, who has successfully ported the Xash3D engine, which is Half-Life compatible, to the little white box, with its 200Mhz SH4 CPU and whopping 16MB of system memory. With the engine has come Half-Life, Counterstrike, and the possibility of many others on DC. Unlike the last time you saw these games, though, they're now glitch-free and are fully playable, with plenty of room for further optimizations left! Speaking of gainz, one of the most interesting battle stories from this project has got to be maximqad offloading some of the engine's allocations for its BSP from system memory onto video memory, which the Dreamcast tends to have an abundance of, at 8MB, with support for a fantastic VQ hardware compression format. For more footage from this play session, check out SWAT's full capture here:

Lane Lambert did not mince words tonight. “Terrible, terrible hockey game for our team. Terrible first 40 minutes… That was the worst 40 minutes we played all year.” On Shane Wright’s play and rumors: “I thought his game was good. It was really good tonight. I think his game's been good for a while. I think there's areas of Shane's game that we're working on that he's improved on a lot since the beginning of the year, the outside noise. The outside noise speculation is speculation. I have no idea, but my job is to make sure that he's ready to play, and I think he's playing well. And I thought he played well tonight.” #SeaKraken

I'm thinking of making something out of the old material that is the basis for many examples referring to the Matrix. But in my case I replaced the Noise Vector with PseudoRandom function in custom node. My goal is to come up with different variations for holograms #gamedev #UE5
