If you're playing this game with one (or two in Crossfire mode) Radeon X1600XTs, you should stick to 1024 x 768 to maintain a smooth frame rate, particularly if you're playing with AA and AF. At 1280 x 960, you're already dipping below the 30 fps mark at certain points and it's just gets worse at 1600 x 1200, with frame rates around 15 to 19 fps. That kind of frame rates can really be annoying, making the game feel sluggish and unresponsive. The minimum frame rates occurs mostly when you're looking at ships or objects at close up or have quite a large number of ships on screen.
By the looks of it, Crossfire isn't applying AFR in this game. So, either the embedded profile explicitly force default rendering mode or there's no profile for this game in the drivers. We think the former is true, since we can see that results with Catalyst AI enabled is slightly faster (though you won't notice it during gameplay), both at 1024 x 768 and 1280 x 960. We'll be looking at how to force AFR in this game, but for now let's accept the results as the default.
Crossfire isn't doing us any good here. While there are differences between the results (about 2 - 3 fps faster or slower) they're most likely caused by normal variations between runs. This may be disappointing, but it's certainly not surprising - we saw the same situation with SLI. Forcing SLI in multi card mode with this game actually made us experience lower frame rates.
