try using a rageconfig.cfg file.
although I have never seen any problems like the one depicted in your youtube video, I have an AMD 5830m, which is based on the same die as the desktop 5770 card and after using this config setting, the textures were noticeably improved:

AMD Drivers installed -
11.9 driver: game did not launch (CTD on startup)
11.9 driver + Oct 3 hotfix: game launched fine, excellent frame rate, excellent appearance except for occasional and very brief artifacting in locations like Ghost hideout. The artifacting appeared as striated thin diagonal lines and did not affect gameplay very much as it was a rare occurance.
11.9 driver + Oct 4 Rage performance driver: no more striated line artifacts, however, in some areas I experienced phantom weapon parts or bullets floating in the air next to my gun. Also NPC flickering in Wellspring.
11.10 driver: fixed NPC flickering/floating bullets etc., and so far no other problems except only one occasion very minor flicker visible in the buy screen with merchant in Wellspring.
