All Games running smoother in Windowed mode, but using same high res - Please HELP!

post #1 of 3
Thread Starter 
Hi guys. I hope this is the right spot for my post. I have a rig around 10 months old, of which has given me a spot of bother with the choppyness of many games.

i7-930@3.8
Evga gtx 570
Asus px58d-e
Patriot 6gb tri-channel ram @1600mhz
Maxtor caviar black 1tb 6gb/s
Samsung SM-P2450H Monitor (1920x1080)
900W PSU
Windows 7 Ultimate 64bit

The thing is, since i built this rig, i have used an ATI 5850 and now the GTX570 to play my games, of which all games ran more choppy with the ATI. My problem doesn't appear to be with FPS, but a smooth output. When running my games in fullscreen (1920x1080) the problem is worse. BUT if i force the games into windowed mode, viola, everything is butter smooth. There is no reduction in resolution when i do this, still at 1080.

If i try to run my games with a lower res but FULLSCREEN, i get the choppyness still. It's kinda like microstutter, when i quickly flick the mouse, or focus on an object like a tree/lampost etc, and strafe around it keeping my focus on the object using my mouse. Here i will see i slight hitch where the frame skips to kinda catch up with itself. If i run my games with vsync/tripple buffering on or off, i still get the problem. I am tottaly up to date with drivers, and have tried it with different mice/keyboard combos to see if it was an input problem. No luck. Even stuck Vista on to try. No luck.

As far as i know i have everything in my Bios set correctly, as have 10 months of fiddling to get the best performance that i have now, but still the damn frame skip/choppy/jerky framerate persists. I have monitored the framerate in fraps using vsync locked to my native monitors 60fps, and the framerate will either dipp, or rise a touch when the choppyness occurs. To repeat, i dont get this problem when using window mode for my games. I have tried a tool to force the 1920x1080 window mode game to fullscreen which works, and is butter smooth. But if i set the game to run in fullscreen via game options, i STILL get the dodgy framerate.

Can anyone shed any light on this please? Why does the framerate improve to a silky smooth 60 fps using window mode, even at the same native res as my monitor sets it to? Thanks.

Sounds like a driver issue. Have you tried reinstalling drivers?

Sure, i have reinstalled the whole OS a couple of times also. Tried reducing my overclock on the cpu (not running one on the gpu). I figured it for Drivers also, but have tried all the ones from Nvidia including beta so far. I have tried both the most up to date drivers for my mobo also including the windows ones. With not too much joy!
