Mesa's CPU-Based Vulkan Driver Now Supports Ray-Tracing
Mesa's CPU-Based Vulkan Driver Now Supports Ray-Tracing
With the merge request that landed this Vulkan ray-tracing support for Lavapipe, Konstantin Seurer shared the screenshot below and wrote "Don't ask about performance"
So… how’s the perf— gets shot
34Gushing frames at 1fps! Kidding aside this is pretty awesome though
21It's actually 0.6 FPS or 1.6 SPF (Seconds per frame)

Hmm, seems interesting. What's the reason for computing the raytracing with the CPU?
16I can see a few reasons:
- automated tests on single frames
- batch renders on a server (e.g. for stills or cutscenes)
- comparisons across GPU archs - it could essentially be the "standard" for how a scene should be rendered
And of course, maybe some CPU manufacturer will build in an accelerator so lower end GPUs (say, APUs) could have reasonable raytracing in otherwise GPU limited games (i don't know enough about modern game pipelines to know if that's a possibility).
Or the final reason, which may be the most important of all: why not?
31I'll add one to this - optimization. A lot of clever optimization techniques tend to come out of projects like this - necessity is the mother of invention.

If the CPUs get strong enough, they could run old raytracing games at some point … especially on hardware platforms that don’t have ray tracing GPUs available for them.

I would like to see the benchmark results from this running on a high end system like a dual CPU EPYC 9754.
11I want to see a Ryzen 7 7800X3D vs Ryzen 7 7800X vs Intel Core i9-14900K.

Can it run Crysis Remastered?
6It does run i think it was OG Crysis at a almost playable frame rate.
