I've been posting around with this:
After running the DX9 Real-Time High Dynamic Range Image-Based Lighting stress test (http://www.daionet.gr.jp/~masa/rthdribl/index.html
) all day (8 hours or so), I find that one half of the screen (the right) is see-through red...Unfortunatlely, I don't have a screenshot.
I've run this extensively before (yes, all day long) and have not had this problem with the program in question. Or any
problems with my system of any kind for that matter. This has only happened since I've installed Service Pack 2...
My GPU temps are around 54C idle, 78C under HEAVY load (like in this test).
All my drivers are up to date, inc. Forceware 71.84.
