Motived by @federico_ponzi's Bare Metal Space Invaders, I implemented Barer Metal Space Invaders😀

@aglitchman 1000 draws by itself is not really a problem for modern GPUs, but if the intention is to render many such buildings, yes -- instancing with a handful of meshes will scale much better.

Sorting the draws on the CPU may be another solution.

Is there any online law about the inverse relationship between the fanciness of a PowerPoint presentation and the quality of ideas contained within?

If not, can I name one?

It's finally here.

Explains how I learned Vulkan and wrote a small game engine with it in 3 months.

It's huge. Hopefully you'll find it useful. :)

[Andres Hernandez @cybereality]

There's finally a new tutorial for @VulkanAPI, showing you not only the API, but how to use it well in an engine (from the legendary vblanco). #vkguide shows you the basics, to drawing with compute shaders and GPU driven rendering. Well worth checking out. https://t.co/5wx2KEzvNq

Happy new year! 🥳

[Nicolas Thibieroz @NickThibieroz]

FSR 3 is now live on @GPUOpen! This release is the culmination of man-years of work from a dedicated team who poured their soul into solving the tough challenge of making frame generation work on a wide range of configurations. I'm humbled and proud to walk alongside them.

The free web version of "Physically Based Rendering: From Theory To Practice" is now based on the 4th edition of the book. Enjoy! (Link: https://t.co/N7CroKjKLC)

@FlohOfWoe @dkapnopoulos Wow that's a lot more work than I expected it to be, considering you already support WebGL. I get each of your points, though.

I am surprised to see that WebGPU includes render bundles aka secondary cmd buffers, maybe for feature parity with native APIs or forward compatibility?

[Tayfun K. @notCamelCase]

@federico_ponzi Thanks for the push! 🙂

Full of gems like this👌

My SIGGRAPH presentation slides about HypeHype low level rendering abstraction and performance (10k+ draw calls at 60 fps on 99$ mobile phone) are now available.

Slides have full speaker notes (everything I said during the presentation).

Questions are welcome!

I’ve written a small library that provides an assert-like macro in HLSL shaders that triggers a GPU memory page fault. Together with Radeon GPU Detective, it may be useful for debugging. https://t.co/pMJY14v19s

[AMD GPUOpen @GPUOpen]

We’re happy to announce the release of an experimental @AMD extension to support #GPU Work Graphs in @VulkanAPI 🌋

Check out the post below for all of the links you need to learn more, including a sample which shows the new extension in action 👇

[Tayfun K. @notCamelCase]

Let there be light (triangle)🥳 Ported my old rasterization sample to my toy CPU, it looks accidentally very cool😄

Partial corruptions are due to non-flushed frame buffer cachelines. Need to implement range-based D$ flush so that VGA fetches are fully coherent before present.

[AMD GPUOpen @GPUOpen]

Don't miss our primer on #Microsoft's just-announced GPU Work Graphs in @DirectX12 🔥

📈 Enable more direct methods of solving complex problems
📈 Reduce memory constraints
📈 Improve cache utilization
📈 Improve GPU thread saturation
📈 And more!

Can anyone guess what causes this trickle-down effect on screen *after reset* ? It's kinda cool 😀

Implementing VGA controller to be able to render stuff at last 🥳

[Tayfun K. @notCamelCase]

Finally fixed a super annoying sporadic hang and a few other bugs to get good ol' Mandelbrot working \o/

The hang was due to double-fetch of some cache-lines when I$ miss occurred after a branch misprediction while fetching the same CL for the last miss.
