My setup crashed the stanford bunny machine learning denoising scene - Intel CoreI7 9700 + RTX 2070. I had no banding this time
I wanted to respond to the previous posted topic, but the api****************.com website wouldn't load. I'm using Blender 2.8.0.
Also had a crash with the sponza scene with machine denoising on - no banding.
Hope that helps.
I will buy some amd hardware in the future. I like what amd is doing.
