Hello again, yes I’m using Windows 10 (Enterprise 1803, Build 17134.885)
The artifacts are visible in interactive mode as well for the first few seconds (until the image clears).
Here’s a screenshot taken during interactive render (width=1360, height=836):
In both interactive and “offline” mode I use --nopbo, otherwise I get:
OptiX Error: ‘Unknown error (Details: Function “_rtBufferCreateFromGLBO” caught exception: Encountered a CUDA error: cuGLGetDevices returned (304): Operating system call failed)’
Here’s another screenshot with part of another render (not using the OptiX Samples) where the effect is stronger (GeForce RTX 2080):
I tried CUDA 10.1 and various drivers ranging from 419.09 to 431.36 but I encountered this every time.
I will let you know if something changes.
