![]() The different Windows versions might also have an effect, I am not sure if 2004 finally fixes the bug of GPU memory loss that has been in there since the initial windows release but it might be possible.įirst make sure you turn on GPU or CPU raytracing before you load the scene so no memory is used up but OpenGL. Windows itself uses GPU memory for drawing its User interface, so a good chunk will already be used up by that. ![]() How is it possible? Maybe not only the gpu memory is involved in this case? On the Z620, working with smaller scene, i can start the GPU RT. Watching the GL Info i see that the memory consumption is slightly different, but in both case is lower then the availability (16384). same nvidia driver (451.77) reinstalled with clean install.Working on the same scene, with the Z6 i can start a GPU RT rendering, while with the Z620 i have a CUDA error for memory overflow. The other an old Z620, double Xeon, 64GbRam, 2 x RTX 5000. ![]()
