People planning to play Splinter Cell: Conviction on ATI hardware, please download the latest Catalyst 10.4a Hotfix drivers. It fixes most of the stuttering and performance issues with the game. I tried the game with my old Catalyst 10.2 hotfix and the performance was going haywire, not to mention, the random crash to desktop issue. I failed to realise that there was a newer driver version since I last updated my Catalyst CCC when AVP had came out. I failed to keep in touch as most of my gaming these days is purely on consoles.
I'm downloading the hotfix right now, will let you guys know how it works out.
