On the first talk, one about rendering optimizations, the speaker (Jan Mróz) compared throughput and bottlenecks between GPU blocks to coveyor belts in Factorio and Satisfactory 😀

Attending #digitaldragons2026 conference. It's always inspiring, with interesting and funny discussions and thoughts. For example, on the pre-party we concluded that soon we should start calling "craft code" (like we have craft beer) a code written by human developers not AI 😀

D3d12info 3.17.0 released, supporting this new SDK: github.com/sawickiap/D3d1…

New DirectX 12 Agility SDK. Just preview version, but I hope these additions will reach the retail version soon. I'm excited about ID3D12CommandListAsyncCommands::CopyBuffer/TextureRegions, clears, and FillBuffers - finally available without implicit barriers around them!

@MrMPFR I dedicated entire articles to the problems with: - Copies & texture clears: asawicki.info/news_1722_secr… - UAV clears: asawicki.info/news_1795_secr… With this change, these problems are solved.

@Reg__ Please ELI5 why highlighted features are a big deal.

@valigo This is so great 🤣🤣🤣 Although I can easily distinguish them because I know both. Polish Win32 programmers often make fun of HWND vs HWDP (the latter being a Polish version of "ACAB").

[Polish] Kto z Warszawy i okolic, w środę 2026-03-25 zapraszam na KNTG Polygon: wykład Michał "Lap-Luck" Biesek: Programowanie GPU i Compute shadery w Godot, a potem mój: Jak działa GPU? Architektura i programowanie współczesnych kart graficznych facebook.com/events/1592468…

Not sure if the “user” side should be other players or fixed scenarios. But surely, LLM responses should be scored by the quality/correctness as well as speed.

This would simulate how LLMs work: no chance to form a persistent memory of a chat, just general knowledge you have + the current context window = generating next token. The difficulty of this would also demonstrate why these calculations are so expensive.

A wacky idea for a game (an indie game or a game jam entry) that makes you feel like like an LLM: You're shown a short chat session with back-and-forth with a "user". Your task is to provide the next word of a response. Just one word. Then, you're switched to a different chat. 🧵

@opinali I think shader compilers are optimizing the code very well. But sure, there is still room for better optimizations if they have more time to process the code.

@Reg__ Thanks! One question: It seems to me the shader compilers are never great at optimization. Perhaps with offline compilation = no need for very fast shader comp, we can have much better codegen into the GPU ISA?

DirectX 12 News from GDC 2026 - My Comments asawicki.info/news_1801_dire…

Total Commander – a Plugin Supporting a Custom Archive Format – a new article on my blog (in English and Polish version) asawicki.info/articles/total…

Looking forward to seeing what DX12 news will be announced at GDC! I won't attend this year, but hopefully they'll share it publicly soon after. I'm especially excited about updates to GPU tools (PIX).

@rade529952 One small challenge was that my Windows login contains space, and Codex has notorious problem with that, forgets to escape the path with quotes "", then experiencing error and fixing it in the next attempt. Happens every time.

@Reg__ That sounds really cool! Have you found any particular challenges when integrating those tools?

I developed a skill for Agentic AI that can query for parameters of the GPU installed in the local system, using vulkaninfo and D3d12info tools. Any feedback is welcome. github.com/sawickiap/gpu-…

Announcing the official release of Shader Model 6.9 and a new Agility SDK! With it comes more expressive HLSL, DXR 1.2 upgrades, and an exciting set of D3D12 improvements developers have been asking for. Check it out here: devblogs.microsoft.com/directx/shader…

New D3d12info 3.16.0 release github.com/sawickiap/D3d1… It exposes new features from newly released Agility SDK 1.619.0, notably Opacity Micromaps and Shader Execution Reordering
