Catalyst 10.1 hotfix Features:
Alleviates some of the intermittent grey screen and vertical line corruptions that may randomly appear during normal usage when using an ATI™ Radeon HD 5800 series graphics card
This will be welcome news for many.
I hope they reveal what is causing some of these grey screens, as obviously many people never experience them. They only time I ever had one was when Crysis decided it wanted to run horribly on the carrier (and seemed to have a major memory leak).
Very glad to find this thread, I have Radeon 5800 & Windows 7 and get grey screen at random moments, either I wait and computer will reboot after a short period or I have to remove power in order to be able to re-boot. I have now downloaded the hotfix and hope for improvement!
