Overwatch 2 Freezing System

If I turn my video settings down (High vs Ultra that usually gives a stable 175 fps on Windows), the full system freezes are a lot less frequent.

Is there a form of closing a program due to low memory in Linux? On Windows I would sometimes have a game crash saying out of memory which I’d much prefer over the whole system freezing. Is this a thing that I can enable in Linux, simply quitting the program that would have caused a system freeze instead of forcing a reboot?

Or could it be a sign of my GPU going out? The only thing that makes me not think that is that I have no issues like this on Windows - the worst would be if I actually did have a lot open and then getting that out of memory error which makes sense.
