![]() The difference in rendering speed of gpu_test_h19 with H19.0 and rendering gpu_test_h19/gpu_test_h19_5 with H19.5 is night and day. gpu_test_h19_5 on H19.5 renders at 100% CPU and almost no GPU load. ![]() When rendered with H19.5, GPU remains practically unused. The results are as follows: - gpu_test_h19 renders at 100%/100% CPU/GPU load with H19.0 (it reaches full load almost immediately). Then, I recreated the scene using operators from H19.5 (gpu_test_h19_5) and rendered it with this new Houdini version. For example, I just made a really trivial scene (gpu_test_h19) consisting of spheres copied to points, one MaterialX shader and a dome light. Anyway, H19 had identical nvidia driver requirements, and yet GPU utilization was always at 100%, even when rendering simple USD scenes. I'd like to avoid installing the driver directly from upstream, as there's a high probability of it messing up my system and giving life to a Frankendebian ( ). The next version which will hit Testing is most likely 470.129.06, which still doesn't match Houdini requirements. 510.x has already been stuck in Debian experimental since early June, and before that there was another 5xx version which wasn't pushed even to Sid. KarmaXPU: Failed to initialize Optix 70400 (maybe old driver? requires 495.46+)And that's not good, because on Debian (even on Testing, which I'm using) there's no perspective of upgrading this driver to the required version in the near future. ![]() 8gb on a 3070 might not be enough for even a single model with textures. Does it say "failed" under optix? I find you need way more GPU memory than you think with XPU. I believe it's too large to upload here, so I'm posting the link. Geometry of the model used in the scene, as well as its textures, can be downloaded from here. I triple checked if Karma Render Settings was set to XPU and that it has the display flag on. One object with one MaterialX standard surface material assigned, dome light and two area lights. Enivob Can you post your problem scene? Are you using all mtlx materials? My test scene is simple as I just wanted to test out XPU SSS. This software is exclusive to Windows, if I'm not mistaken. jsmack Try using GPU-Z or MSI Afterburner/EVGA X1 to get a more detailed look act power consumption. Unfortunately, nvidia-smi doesn't provide information about CUDA load and I don't know of any GNU/Linux software that would do this. ![]() It's so low that fans of the video card won't even start revolving (they're at 0% throughout the whole rendering). ![]() I believe it's too large to upload here, so I'm posting the link.Ījz3d Hi guys, jsmack What is power usage?GPU power usage while rendering peaks at about 28 Watts.
