I am using a new laptop with Quadro T2000. The software I'm using is Sketchup 2020 and VRay 4.20. If I select the CPU render, the image result is as expected, perfect quality, no noise in 18 minutes (Intel i7-9750). If I select CUDA or RTX, the result image has a lot of noise and takes 4 minutes.
I attach some screenshots of the render options I am using. Also, I attach the CPU and GPU image result, where the noise can be noticed.
Are we missing some options in the render? Drivers are up to date to the latest version and we are using Windows 10 also last update.
Thanks for your help!
