after getting a 3rd monitor, my game now 'stutters' when i alt tab back into it. fraps tells me i get a solid 60fps (or more in some games), but it looks more like im getting 15 after i tab back in. after a while, the stutter goes away but sometimes randomly comes back. this didnt happen when i had 2 screens, only started happening when i got the 3rd screen. running on borderless or fullscreen changes nothing, and ive tried installing the newest drivers.
