Profiling "optixLaunch": stuck at 0%, seems like a deadlock

Developer Tools Nsight Compute

I’m trying to profile my OptiX app using Nsight Compute, but profiling optixLaunch is stuck at 0%, even though the program takes only 1 second to run without Nsight Compute. Other kernels (optixAccelBuild and optixAccelCompact) work fine and are profiled correctly.

I also tried basic mode for profiling, but the result is the same.

How can I fix this problem?

I’m using Nsight Compute 26.2.1.0 with CUDA 13.2 + OptiX 9.0 on Windows 11. My GPU is an RTX 5090.

The GPU driver was the problem. I was using 595.97.

It works after I upgraded to the newest version.
