OK. It looks like there were some crazy stalls slowing everything down. I don't have an explanation for that, but I think the shader compiler performance...

Not so fast, cowboy. The chart seems wrong. If you look at the Total Frame Time chart, it shows that average frame time = 5.62, so: 1000/5.62 = 177 FPS....

They are not CPU threads of course. They are GPU threads in the GPU sense, and the GPU sense is pretty arbitrary between vendors.

Yes, all shaders run on the same CUs. I wouldn't use the term SIMD or SIMT, because GCN shaders have both vector and scalar instructions, and both vector...

Modern GPUs still have vertex, tessellation control, tessellation evaluation, geometry, and pixel shaders.

The tessellation itself is done...

Vega was not a die shrink. It had many hw changes that made it a different GPU from Fiji....

[marek]

Serious consequences for bugs? Do I understand it correctly?...

[marek]

The software industry is lucky that you are not a manager of software development....

[marek]

Games already use alpha-to-coverage instead of alpha-test....

It looks like that only Wayland & Weston are moving to GitLab.

[marek]

It's using the closed-source shader compiler here, not LLVM....

[marek]

shader-db was bottlenecked by the 3-thread shader compiler queue, so it only used 5 threads or so on a 16-thread CPU. Now it's using ~16....

Yes. All Mesa DriConf per-app options can be overridden by users and apps freely.
