Chief-007 Posted Wednesday at 03:58 AM Share Posted Wednesday at 03:58 AM Hi guys, Very stupid question. I am new to rendering with CA, I am trying to use my GPU(NVIDIA 5070) instead of my CPU when using the ray tracing feature. I have read a few forums suggesting going into settings-> graphics card -> High performance. I have gone into the NVIDIA app as well as the control panel and made sure chief was added. I checked my video card status and it says the 5070 is being used. However, once I start ray tracing and open up control panel, it shows that only CPU is being used when ray tracing. I need to know if Ray tracing is CPU only or if I am doing something wrong and using my GPU IS possible. Link to comment Share on other sites More sharing options...
SHCanada2 Posted Wednesday at 04:24 AM Share Posted Wednesday at 04:24 AM there are tow different types of ray tracing. CPU, and Realtime. open up a floor camera, edit it's settings and change to "physically pabsed Link to comment Share on other sites More sharing options...
Chief-007 Posted Wednesday at 04:41 AM Author Share Posted Wednesday at 04:41 AM Follow up question, are they the exact same thing?, the only difference being Physically based uses GPU and raytrace uses CPU? or is there a significant difference between physically based and ray trace?

Rich_Winsor Posted Wednesday at 06:43 AM Share Posted Wednesday at 06:43 AM No they are significantly different. The most important thing to know is that Chief has abandoned CPU ray tracing in favor of PBR and are letting it die on the vine. New features in PBR (like grass regions) are not being adapted for CPU ray tracing use. I for one am not convinced that PBR renderings are of superior quality to CPU images, but mine is a voice crying out in the wilderness. Link to comment Share on other sites More sharing options...
