It isn't you. The AMD opensource team has been doing a terrific work lately, especially considering the small size (IIRC 4 people). DPM is the big thing, as it means that the gpu can raise the clock under load as it does on Windows, but they've done lots of work everywhere else as well. Say thanks to Intel as well for driving the work on Mesa (It's thanks to Intel that Mesa got OpenGL 3.3 compatibility so fast). Also Wine got some speedups as well (and an huge one should be coming soon with the stream patches). Overall, I'd say that the Linux graphic stack has never been in a better state. We got official opensource drivers for Intel, official opensource drivers from AMD that are 50-80% as good as the closed one depending on your card, and unofficial opensource drivers for Nvidia that are usually good enough for non-gaming.
