Friend o' mine just got a 9800 Pro from Retek but there seems to be some slight problems with playing CSS (other games run perfectly - NFS: Most Wanted / Quake 4). It'll play in 'high' quality and everything will appear fine but then a kind of interval lag/judder sets in. He gets a constant 55/60 fps so it doesn't seem to be directly linked to graphics but then the problem goes away when CSS is set to 'low' quality and I don't think it's his connection as his ping remains the same. Windows is a clean install and we've tried the latest ATi/Omega drivers but it just won't go away.
Does anyone have any ideas? Many thanks.
