I've tried flying low over London after this latest update. Oh and Damascus as well. I run the MT thing in stable version and my settings are pretty high there (and I'll keep them at that, thank you). Anyways, my GPU (Nvidia 3090Ti) goes hot after 3 or 4 minutes of low flying (really low flying OK) - going up from 55C rapidly and topping at 75C. And then it shuts down. So it's black screen Happens over BOTH Damascus and London, with a Spit of course. I've also noticed how quickly the GPU recovers if you go skywards. It can go from 70C to 60C in ten seconds or so.
So then, I'm VERY happy with the performance we've gotten but my GPU obviously can't handle big cities anymore. And I won't do anything about it because it works just fine with everything else (IL-2 modern and old). I could of course try lowering the graphic settings but I'd rather not.
Cheers
