I switched to CUDA 12.1 + Optix 7.7, and it is up and running now. The GPU version runs more than 10 times faster than the CPU version (4.7s vs 48.7s). Thanks a lot for helping!
The CPU version runs normally, but when the "--gpu" flag is added, the program keeps running indefinitely, and the prediction time is shown as "?". My display card is RTX4070. CUDA version: 12.0 OptiX version: 7.5.0 I don't know what the problem is. I noticed a warning:
CUDA_ARCHITECTURES is empty for target 'pbrt_lib'
, but I'm not sure if this is the cause. And I tried CUDA version 11.6, it also did't work.CMake-GUI Info:
