Serious Graphics Glitching... at 120 FPS =P

I currently run an Nvidia GO 7800, and with the settings set to "balanced" I can normally run GW at 120 FPS.

Oddly, over the last three days, whenever I play ANY game at maximum resolution my screen will begin flashing/twitching/jerking randomly during play even when my FPS is through the roof.

I tested this with GW in windows mode the other day and noticed that the game normally runs at 50,000k on my machine in processing power, but at these spikes will go up as high as 200,000k.

I have not changed anything in my computer recently and I have never had trouble with this before. My drivers are up to date, and I defragmented my disk last night. Does anyone have an idea?

"50 k processing power"

I seriously never heard that before.

i think he means ram usage . ..

system restore to 1 week ago ?

Maybe you're talking about tearing? See if putting V-Synchronization helps..

I have a similar problem. Suddenly, these little glitched squares appeared. Sometimes there is whole screen full of them.

Do they appear randomly? They look like they could be artifacts. Small glitches generated by your gfx card because it's either overheating or generating a fault. Check to see the fan on your GFX card is still working and that the heatsink on it isn't coming loose.

This happened to me once, for some reason the HS started to work lose and I was getting all sorts of probs like this. Bought a new fan+heatsink and all was well.

It sounds like the artifacts are caused by out of sync "bits" of video. Do you have vertical sync turned off in game and/or video card settings for the fps boost? If so, you may be seeing the side effect of that decision.

A good counter remedy:

Force triple buffering via a utility like ATI Tray Tools and enable vsync if it's disabled. (no sense forcing triple buffering if you don't enable vsync, just a waste of video memory)

Yes, vertical sync dampens FPS but with triple buffering forced that negative effect is mitigated.

Pointing my desk fan towards my video card seems to have done the trick.
