No real issues on my end - the screen goes black, the card fails, the engine/game picks right back up where it now is (cpu still computes) as soon as the card comes back.
It’s proper error handling vs unreal error handling.
In some rare cases - the ones where you usually see a bsod happening about 10 seconds later - then there is a silent crash - no error thrown, the editor completely exits.
Still. Get a new GFX. That’s the sane thing to do.
You are bound to have issues over any 3d program if its overheating to where you get the issue constantly.
Note that Nvidia drivers are still bad for multi-monitor setups that use mixed settings. And that almost all programs have a lot of difficulty not giving you black screen flickers when your main monitor has hdr on. Regardless of 30x serires model (seriously this is the same from 3060 to sli double 3090tis). Unfortunately doesn’t seem like something nvidia cares about.
