I recently decided to splurge a little on upgrading a friend's computer. He has a HP Pavillion a1310n that came with an Ati X1300 card and he definitely needed an upgrade so I bought the Radeon HD 4850 to replace this.
Every other game he has runs like a dream, NWN2, Oblivion, lolWoW with no issues at all however now when he goes to play final fantasy 11 it will initially start up fine... but after a while character and mob models will not load. The effects will still go off and names will appear but no models at all and the game becomes very laggy. Eventually FFXI crashes with a "cannot write XXXXXX memory (i can get the exact message, it just gave an address that idr). If he tries to open PlayOnline back up the window is a black box. It requires a system restart to get it to load again.
He is using the latest version of ATI's driver offerings... 8.20.somethingsomething... I looked at Omega Drivers but it seems 4850's are not supported yet... (or i'm just blind) Any assistance or ideas on how to resolve this would be appreciated. Its an Athalon 64 processor, 1 GB of RAM... I can furnish more specs if needed.
Thank you for any ideas or help.
