at first, sorry for my bad english, i try my best.
i use Windows Vista Home Premium 64 bit
ATI Radeon HD 4800 Series with 1024 MB Ram
The Catalyst-Version 13.1 (Treiber-Packetversion 184.108.40.206-121116a-151639C-ATI)
if i try to start Bioshock, i become a message from Steam that my Graphic Driver is to old (Version 220.127.116.119) and i must install the new Version, the Version i allready have. Even the automatic Graphicdriverupdate from Steam itself say that i have the up to date Driver.
What can i do to get the Game running?
Thanks up front for answering
