Performance issues while fullscreen

[Bunta]

For some reason when I run at full screen no matter the resolution my FPS drops to around 45 and I get terrible tearing, If I switch to windowed mode on the same resolution I get full 60 no problem. I've tried full screen with Vsync on and it just locked me to 30 FPS.

I'm running on a i7950, GTX470, and 8 gigs of ram with W7

Like I said, the game runs perfect under windowed mode at 1080p but runs sub-par in full screen mode no matter the settings or resolution.

Are you using HDMI or DVI connection with your monitor?

I am, HDMI.

That is the problem, I'm having the same issue.
Since 1440p isn't supported, I was just going to play it on my TV instead, until I read about the HDMI thing so now if I do full screen, its 30fps and the highest res that isn't a blank screen is 1680x1050.

Specs: I7 950 4.2 GHZ, GTX 780, 16GB RAM, ASUS ROG Extreme Formula III, Windows 7

Awesome, Thanks a lot for the help. I can just play windowed and it isn't too much of a bother. I didn't even realize this was an issue.

Having the same problem. Going full screen somehow makes the game look darker, with bad fps and lags.
On windowed it looks perfect.

I have a 1080p tv and gtx 670 Ti

Please fix this !
