Hello everyone, I'm having a major headache with my Radeon 9800XT and was hoping someone here could point me in the right direction for a solution. My system is a Dell Dimension 8300, exactly four years old this month. About three months ago, strange chequered patterns started appearing in Google Earth, though every other application and game seemed fine. I decided to upgrade to the latest Catalyst release last week and things have gone downhill ever since. WIth the latest driver, things like scrolling in a browser have become very slow, and even moving a window across the screen. Google Earth refuses to start now, throwing up a dialog box with the title "DirectX mode not supported". Also, in the DirectX diagnostic tool, features such as DirectDraw Acceleration are listed as "Not Available". (I have DirectX 9.0c). I've tried a number of possible fixes that I read in other posts on this forum - rolling back the driver to an earlier release was one, as someone said they didn't think the latest ATI drivers did not support AGP 100%. However, no release I've tried has worked. I'd really be grateful if someone could throw some light on what may be wrong and how I might fix it. Thanks.
