LuxMark v3.1hangs with render scene missing when chosing Native C++ on Linux
Opened this issue · 0 comments
Hello
Whenever I choose Native C++ in my Linux installation, the render scene never shows up, despite my CPU going to 100%. The CPU stays at 100% even after the 2 minutes for a benchmark. I tried all 3 scenes (hotel lobby, Neumann and LuxBall, same result. Tried with Fedora 38 with Wayland and openSUSE Tumbleweed 2023-07-18 with X server. Selecting BENCHMARK_NATIVE on the command line shows the same issue. The text output in LuxMark window shows no error and stops at:
2023-07-23 21:05:31 - [LuxRays] [0.772] Total vertex count: 124324
2023-07-23 21:05:31 - [LuxRays] [0.772] Total triangle count: 217544
I believe this used to work some time ago, and now despite I use the same LuxMark v3.1, it is not working any more ... I used a fresh Linux installation, native (no VM), and the render scene never shows up.
It works as expected if I choose an OpenCL device, but not for Native C++. I have an AMD Ryzen Threadripper 1920X CPU.
