I think it can even be done while playing a game. I've never seen Windows Update (when set to update drivers) asking me to exit any program.
Basically what the title says:
Does playing games (having them open or actively playing it) while updating graphics drivers affect anything in a negative way, besides gameplay (obviously)? Like, can the update go bad, could it corrupt data of either the game or the driver, etc.?
I don't expect that to be the case but I'm just wondering.
