Yes AMD are guilty of being difficult to say the least here, i actually found the legacy drivers once but when i tried to download one it said i needed to sign in first ?? Sign in to what ?? No link or anyhelp as to what you needed to join to sign in to just sign in or cancel
Support stopped at 9.2 and they list a 10.2 hotfix driver that works for some and not others it seems from reports from people who have tried it.
You could always try Omega drivers, i have used them before and they are actually based on the 7.12 driver last i looked. Last time i used then was about 8.12 i think, they worked better than those drivers though. In my opinion anyway.
