So the problem's on my end?
Well, yes and no.
If all the RAM you have is 4GB, that's a bit low, yet it depends.
Some games in wine have excessively high VM consumption and (next to) nothing can be done about it (there is - for example - a case where winegstreamer can kill a game with vm exhaustion despite the game using very little memory (well, I haven't rechecked that bug (or two) in a couple years, but I don't recall any changes there since, major enough to make a difference)). In other cases though the excessive consumption is a genuine bug and can be fixed.
Which case we're dealing with here is still uncertain.
