I'm running Windows 10 with an RTX 2070 & an RTX 3070. I've been working with the 2020.2.5.1 plugin with few problems and my Nvidia version is fairly recent.
Decided to try 2021.1. The image I was rendering got segregated into 2070/3070 sections with the 2070 section looking considerably darker than the 3070 section. Also, when rendering the same scene with both plugins I found 2021.1 had a strong red cast over the whole image whereas the previous plugin was neutral.
So I had to roll back. 2021 is called EOL Tribute. Does that mean there will be no further updates? Because it appears it needs one.
