It seems that some folks are getting an error that shows “Your computer is low on memory” even when it is not. The issue seems to happen mainly when playing games in fullscreen.
Possible cause: You are running one resolution on your desktop and a different one in the game.
Solution: Change the resolutions so that they match
I am not sure if it is a way that Windows handles the desktop now or if it is some sort of driver issue causing it to happen. If I get a better solution for this problem I will be sure to update this post.
