So, as is to be expected from games nowadays, GPU optimization on day one is always ♥♥♥♥. Even moreso in the case of ATI cards.
And such was also the case with Red Orchestra 2, where my setup of 2xHD6950 which should, by all means, be able to eat this game for breakfast, was only getting me a poor 30FPS when nothing is going on (I measured the FPS in the training mission)
This was on Ultra settings with Occlusion on and AA set to Medium.
But there exists a nifty little tool that I've been using to circumvent poor Crossfire scaling, called RadeonPro, which is what we'll be using here today. I'm positive some of you are already familiar with this program, but then again you've probably already applied a fix.
As for those who are unfamiliar with RadeonPro, here's what you gotta do:
1. Download and
install RadeonPro (duh); I posted the link above.
2. Once it's installed, start it up and click on the "Add new profile" icon (it's located on the toolbar at the top of your RadeonPro Window)
New Profile
3. Navigate to your Red Orchestra 2 executable and open it.
RO2 Executable
4. Select your ROGame.exe profile and on the right-hand side, navigate to the Tweaks tab.
5. Under Tweaks there's a section called CrossfireX Tweaks. There you'll find a drop-down box under Force CrossfireX Profile.
Use the drop-down box and find the Bioshock profile, and select it.

6. After you're done with that, right click your RO2Game.exe profile and click "Apply now"
Now here you can also disable the FPS counter and other GUI elements by clicking on "Disable API monitoring".
You can leave this on at first to see how much of a difference in FPS there is pre and post-fix.

7. Basically you're done! In addition to this, there's, naturally, some more obvious fixes, such as disabling Ambient Occlusion and AA.
Well, that's about it. Doing this got me an extra 15-25 FPS, which I consider to be a pretty good gain for a temporary fix, that doesn't involve toning down settings.
You can also try some of the other available CrossfireX Profiles and see how they work out. If you find a profile that works better than Bioshock, please tell us about it!
Keep in mind, though, that there might (emphasis on might) be some side-effects, like graphics glitches and such, depending on which profile you're trying out.
I hope this guide was coherent enough, but if you have any questions, feel free to ask.
