I have a Radeon R9 270, where can I get the proper graphics drivers for this card? I've tried a few graphics drivers already but none of them seem to have any affect towards performance and compatibility, specifically with games.
Have you tried the drivers from AMD's website?
AMD Graphics Drivers search for Radeon R9 2XX Series
The search result was the AMD Catalyst™ 14.4 Proprietary Linux x86 Display Driver.
