What OS are you using? What resolution are you running at? Have you filed this report in Catalyst Crew Feedback: http://www.amd.com/us/CatalystCrewSurvey

Windows 7 64-bit, 1600x900 with both versions, and no, didn't even think of reporting in the survey. Thanks for the link, I will right away.|

Edit: For now I'm reverting back to the 10.1 Catalysts. I'll give the 10.4s another go tomorrow when I'm not tired, for now I just wanna play CoH.
Okay, after some testing between the 10.1's and 10.4's, it seems to be 4x anti-aliasing the 10.4 catalyst's having trouble with. If set to 2x AA, I get the same framerate with both drivers, but when I up it to 4x, I see a big fps drop in the 10.4's that doesn't occur in the 10.1's. I'm gonna stick with the 10.4's for the time being though to test out a few other things.
Okay, so the official ATI 10.4 Catalyst drivers came out. I cleaned out the older 10.1's, including using Driver Sweeper and installed these. I lost about 10 fps with the 10.4's, and I'm trying to figure out what's causing it. My card is a Radeon 4850 512MB with these settings;
Catalyst Control Panel
Anti-aliasing: Application Controlled
Adaptive Anti-aliasing: Quality
Anisotropic Filtering: Application Controlled
Catalyst AI: Advanced
Mipmap Detail Level: High Quality
Triple Buffering On
In-game
Anti-aliasing: 4x
Anisotropic Filtering: 16x
Character and World Detail at 100%
Bloom: Heavy at 100%
Depth of Field Off
All Ultra Mode settings maxed out, except Ambient Occlusion which is off
At these settings, wandering around Kings Row gives me around 30 fps with the 10.1 Catalysts. With 10.4, it goes down to 18.
