My computers desktop resolution is 1400x900 and my games I play on there I always set their ingame resolution to about 1024x768 so I can get better performance out of my games. The only thing that bugs me is when I close the game and it switches back to the desktop the screen flashes a few times before it goes back to the desktop, I figure it is resizing itself back up to the bigger screen size. I was wondering if I am stressing out my computer by doing this switching between the 2 different screen sizes?
