I've noticed that while playing in windowed mode the game crashes quite a bit more, actually, I don't think I have crashed in fullscreen. However, as soon as I turn windowed on, restart the game and hop in a multi-player server (even single player, though less often) the game will crash eventually, these methods seem to "stimulate" a crash:

-While loading in the game.
-Checking inventories in vehicles (specifically trying to take a gun.)
-Even just running about. {F17085}
