NVIDIA Fermat OptiX-RTX ray tracing benchmark
« on: September 12, 2018, 08:35:37 PM »
Hi, in the last couple of days I was working hard to create a custom ray tracing benchmark targeting RTX class GPUs. I managed to set up NVIDIA's Fermat rendering engine, it's based on CUDA and uses Optix Prime for ray-triangle intersection. Naturally, Optix supports Pascal and Maxwell, so we can compare the "prev-gen" GPUs with the RTX 20-series Turing based GPUs in ray tracing scenarios.

Starting point: https://github.com/NVlabs/fermat
My write-up: http://boostclock.com/show/000219/gpu-rendering-nv-fermat-gtx980ti-gtx1080-gtx1080ti-titanv.html

I added some cmake magic and made it to run on Maxwell and Pascal as well. For now, I only tested on Windows. Eager to see what kind of performance the new 2080(Ti) will deliver. Supposedly, Optix 5.2 and CUDA SDK 10 will have Turing support in it.

Let me now what you think! Cheers!

I suggest to provide precompiled binaries.
Most people are either unable or too lazy to compile the stuff themselves.

Agree with Stefan, a ready to use demo is better if possible.

Okey, I will double check with CUDA SDK 10 and RTX GPUs and create a pack from it!
