3D apps have started hitching :(

Howdy

I've recently noticed major framerate drops every few seconds, rendering my games unplayable :/

My GPU isn't throttling, or overheating, but I get the following error message over and over in EventViewer:

0000000003: 2009-04-26 01:09:12:834    Unable to obtain Color Correction information, dem status: -2

I'm running Windows7, with cat 9.4's.. please tell me my 4870 isn't fubar :/

tried a driver reinstall?

I have. I've just taken my machine apart and made sure all contacts are clean, and the issue persists.

I'll downgrade to 9.3's, see if it still happens..

*edit*

It only seems to happen when I have high AA applied.. just ran 3Dmark Vantage, and got the correct score. Just played Demigod with 2xAA, and it's fine. 4xAA, and it hitches to hell - I've been playing it at 4xAA without hitching for ages :/

I assume this points to the graphics ram fubaring?

I'd suspect the beta OS you're running before pointing the finger at the ram.

I've booted into my failsafe Vista install, with the same problem.
