@FritzUnderstandable! Thank you for pointing out the downside. But shouldn't that also be a problem with Redshift on a dedicated GPU? RS really profits a lot from a dedcated GPU and the data transfer seems unproblematic? I'm no dev though, so I'll just take your word 🙂
@Mike AActually, having the 4090 dedicated for Redshift solved multiple problems for me:
There's a nvidia Driver bug going on for a year, that doesn't free VRAM properly of the display card. Having a GPU dedicated to Redshift circumvents the problem altogether
The 4090 gives me a _crazy_ fast IPR, almost realtime in most scenes
... and the viewport stays super responsive, because it's handled by the 2080.
I can do full renders in the background and still work on lighter stuff in the foreground (Premiere, Photoshop, etc.)
The effect of additional overall responsiveness of the system was totally suprising for me. So I'd like to keep the 4090 as the 'monster in the barn', but I hoped I could feed it Pyro as well 😄
