Default Re: Graphics Artifacts 6800 Ultra AGP :(

I get minor issues with this in Halflife 2 mods, more major issues in Halflife 1 mods, severe issues in any game where I turn on HDR or Bloom effects and when it does appear, anywhere from five minutes to an hour into my game, performance then degrades over the next few minutes until the game crashes, by which point the view is almost completely obscured by these stretching textures and effects, depending upon where I look.

The stretches actually grow across the screen in real time depending upon my view.

I'm not tech-educated, I have no unusual settings or programs related to graphics and I am not overclocking.

Average temperatures on the card (i've heard a lot over overheating due to a loose fan on the 6800s) are an ambient of 45-55oC and a Core temperature of 65-82, depending on whether I'm on my desktop or running a graphics intensive game.

These temperatures are in the middle of a southern-uk winter, with heavy snowfall and below zero indoor temperatures. It should not be overheating, it should be turning into an icicle! I certainly am o.o

I'm also running the latest drivers.

Any help would be appreciated.
Maybe you could try to get an artic cooling NV5?
It would also be good to have an extra fan blowing at th back of the card where all the voltage regulation circuitry is. 45-55C ambient is bad... the little thermo-diode is quite a way away from the video memory and the regulators, so they must be considerably hotter than that. Make sure you dont have dust accumulating and very good air flow. Maybe try running with case open and on its side.
