After (finally) getting the 4870x2 to run correctly under debian (lenny), the only issue I'm still having is low frame rates.
I am currently using the latest drivers from ATI's website (the drivers installed by apt (proprietary or otherwise)) did not work for me at all as far as 3d acceleration goes.
The game I have been testing with is World of Warcraft run using wine. (I have used both opengl and directx, both give the same results.)
Running the exact same setup in windows usually averages me ~150fps or so, while I achieve a maximum of about 50 under linux (which doesn't sound so bad, but the mouse feels sluggish and everything just doesn't seem as snappy as it should.)
Now, I'm wondering if there is anything I have left out as far as the setup of the card goes. All I have done is install the drivers from ATI's website, which, looking at the xorg.conf file, has set everything up properly for their use.
I'm just wondering if there is something I'm missing that's slowing the card down, or is it just the fact that ATI's linux drivers are subpar? If that is the case I suppose I will have to get rid of it and grab an nvidia card ...
Any help or input is greatly appreciated
