    Because phoronix is the only place you can see benchmarks of linux games and they continue to frame AMD cards in a favorable light (though not nearly as bad as they used to). Back when I had both ATi and nVidia cards reading the ATi articles here pissed me off, because I knew first-hand how terrible the drivers were compared to nVidia's. Anyone really wanting to see linux succeed on the desktop wouldn't have recommended ATi cards to anyone at that time. These days I can't comment since I'm ATi-free. It does seem like there is improvement in the drivers over those days. I'm actually hoping they catch up with nVidia, because I'd like to see strong Trinity support and performance.

      Just curious. I haven't noticed anything like this with a 4870.
      0,5 or less. It's happening when I'm fighting bots in ut2k4 and sometimes in other situations.

        It could be possible that some settings are just completely ignored by oss drivers. I saw speed issues with Intel onboard as well, i had to disable AA to get good framerates (AA is not that critical with high res, AF you see more). I would begin with less demanding settings first, no forced vsync/aa in amdcccle, just in app. Comparing oss against binary drivers is just like comparing apples and oranges.

          I had default Catalyst settings. I'll play a little more with it, but I'm nearly sure Catalyst is the culprit here.
