I found another person getting more than 60 fps on the same program from OptiX 7.2.0 SDK using Windows 10 & RTX 2080Ti, so I feel like this is an unreasonably slow render time.
What am I missing? What should i do to improve the render time?
Hi @friskneoaddict!
That’s a debug build I suppose.
The CUDA debug code is super slow. In CMakeLists.txt:
remove or comment out
optix_add_cuda_flag_config( _${config} “-G” )
and
optix_add_cuda_flag( “-G” )
and rebuild.
This solved the issue! Thank you!
Turns out it was just a stupid beginner’s mistake.
According to CMakeLists.txt, it’s supposed to build in debug mode only when it is toggled inside Visual Studio (which i unintentionally did), so it worked just fine when i changed it to release mode.
Just pointing out that by removing the -G option you can run debug builds at decent speed, you just will debug host code only.
