RadeonPro CrossFire Tweak - Major FPS Boost!
 

Here is a tweak using RadeonPro utility: http://www.radeonpro.info/en-US/

In “The Black Death.trk” using "very high" settings my FPS went up from average: 20, max: 64 to average: 42 / max: 122. All 4 GPUs are at about 75%.

The only issue encountered was some menu and mini-map (multi player) corruption. EDIT: Disabling API monitoring in RadeonPro setting resolved corruption issues.

Your experience may differ! ;)

Here are the settings:

EDIT:

Different cards may require different settings.

I had issues with flickering using some of profiles. For those with flickering problems be sure to try different crossfire profiles. Remember DX9 cards may not work with DX10 profiles...

Also, try disabling API monitoring. This helped with menu corruption.

Glad that you are getting all together.

I guess that AMD will not release a Application Profile for IL2COD until the USA launch, so yeah ... good work :-)

Multiplayer is even better!

Went from sub 20 average to an average of 66! Getting some mini map corruption, but still worth it!

Nice. And we SLI users still wait. Sucks.

Great gonna give it a try soon and let you guys know!:)

So what is difference between the Radeon Pro settings and CCC settings?They look the same to me.

About twice the frame rates. :-P

It uses DX10 crossfire profile of the "Lost Planet Extreme Condition" and gives a higher priority to the thread.

I can say this WORKS like a beuty, i got steady 60FPS over London and really ZERO stutter, Little stutter when maxed.

How you get that MVPU=1 settings??

Thank you roadczar for find.

EDIT:
My only problem is i see sometimes when start the game terrible flashing whole my screen.

Nice to see Londow without stuttering and no rubberband at all, smooth as butter.

Did anyone try linking a 3dmark profile to Launcher somehow?
Drivers should be optimized for benchmark utilities like 3dmark pretty aggressively.

In ArmA you could rename arma.exe to 3dmark.exe and have a significant performance boost, x-fire working, etc.
Steam does not allow to rename Launcher.exe but there could be another way to load 3dmark profile.

ps. Where the above mentioned Lost Planet profile comes from? Is it built in this utility or should be downloaded from their site?
