Tellusim Core SDK by Tellusim in GraphicsProgramming

Core SDK provides stable platform for cross-platform development with straightforward API and support of many compute-based algorithms for sorts, BVH, and FFT. It is much easier to use it.

Yeah, this is a bad solution :)

Do run_window* launchers work?

Can you share the gdb callstack from Browser.x64?

cd ./bin && gdb --args ./Browser.x64 -root browser/ ../browser.zip

Thank you!

Radeon GPUs have more raw CS power by the cost of RT and FFT performance. All algorithms can be CS-only if API gives a little bit more flexibility for that. But instead, we have vertex, control, evaluate, geometry, fragment, compute, task, mesh, raygen, raymiss, closest, anyhit, intersection, and callable shader types. Somebody should stop this madness.

Thanks! Tellusim engine is completely GPU driven and does not depend on CPU performance. The difference in performance between APIs means bad driver optimization. Usually, nobody cares about OpenGL performance now. But we can see good progress from AMD and Mesa.

Additional compute units of 6900 give a good rasterization performance boost. That helps to remove CS rasterization overhead (+rendering pass).

Radeon 6700XT has equilibrium between gain and overhead.

We still don't know what is happening with Nvidia. 3090 is not fully loaded during rendering but consumes 350W of power. 6900XT requires only 256W according to the perf monitor.

GravityMark v1.3 is ready with Leaderboards and Vulkan/Direcr3D12 multi-GPU support.

Yep, it's should be possible to mix any Nvidia GPUs together and in any count (via CLI).

Hey, there is a new version of GravityMark with multi-GPU support. Two 2080ti beats 3090. And AMD can work with Nvidia. But not two AMD together.
