Adding index buffer for my VkCube NoGraphicsAPI port. +2 lines in total. You simply gpu_malloc space for indices, memcpy (or write) indices there. And then pass in that GPU pointer to draw_indexed. This is doable with the brand new Vulkan device address commands extensions. ht 400 views · 9 likes · 0 reposts · 1 replies 04 Sep 2026 Isn't this sweet (VkCube ported to NoGraphicsAPI): https://t.co/MpAcVwzR8v 1K views · 11 likes · 0 reposts · 2 replies 04 Sep 2026 I have been cleaning up examples written by Codex (5.6 Sol Ultra). So much code bloat. But there's real stupid code too. It wrote CPU->GPU barriers (no need, queue submit guarantees visibility) and one command buffer + submit per render pass. Not performance optimal at all. 1.9K views · 33 likes · 1 reposts · 7 replies 04 Sep 2026 PS5 Pro has the same nerfed Zen 2 CPU as the base model. 4x smaller L3$ than desktop Zen 2 and half rate AVX and lower clocks. GTA6 is CPU bound simulating a big city. PS5 Pro has 1.6x GPU perf and PSSR2. GPU could hit 60 fps at higher scaling ratio (but better upscaler). 7.4K views · 100 likes · 12 reposts · 9 replies 03 Sep 2026 @SebAaltonen Very nice. I'm surprised you didn't talk about raytracing at all in your post/talk though! I think there's quite a few issues with the RT APIs as we speak... Like Vulkan/Metal not exposing AS memory, so you can't store BLASes on disk, no indirect TLAS build... 1.3K views · 6 likes · 0 reposts · 3 replies 08 Aug 2026 Based on my blog post from last Christmas. This new presentation also discusses brand new Vulkan extensions released since, and discusses the issues of the bloated shader framework (a topic I want to discuss more in my next blog post). https://t.co/uL8HsfHNYn 4.7K views · 61 likes · 6 reposts · 1 replies 08 Aug 2026 Extended (2x) version of my SIGGRAPH 2026 talk: https://t.co/VjyYRhgz8t Reducing Graphics API Complexity: A Clean Slate Design for Modern GPUs 68.3K views · 758 likes · 117 reposts · 20 replies 08 Aug 2026
