About twice the frame rates.

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?

Sounds promising. Going to give it a try when back from work.

Please share your results. I am thinking of adding a 2nd 4890 as a temporary solution till nextgen cards introduced later this year.

OT: How much you managed to OC your 4890s by the way?

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:

Congratulations! +100% Nice work!

Keep it up!

Different cards may require different settings.

I also 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.

ok Guys, did some more testing...mixed bag of results unfortunately.

I tried some different profiles as roadczar suggested and ran the blackdeath track with the following results:
Lost Planet Extreme Condition (DX 10) - FPS avg 51 but flickering
Call of Juarez - Flickering
Unreal 3 - no improvement of FPS (41 avg)
Crisis - Flickering
Dirt 2 - no flickering and avg FPS of 52 (decent increase)

All above in True Full screen, V-sync off. Also ran msi afterburner to check both GPUs on my 5970 were being used.

I also did a run of the track in Pseudo mode, with the Dirt2 profile enabled (just to see what happened) ... avg fps was back down to the standard 41 and msi afterburner showed only one GPU being used.

So from that, the Dirt2 profile seemed to do the trick. Whilst actually flying a mission however, it was unfortunately a different story.

I have a variation of the QMB mission "Airfield Attack - Mansfield" set up for testing. Whilst playing with the true full screen and the RadeonPro settings, performance seemed to be more sluggish with stutters down low...avg fps in the low 30s. I had also turned on v-sync and triple buffer to eliminate the track IR tearing.

I went back to my usual Pseudo mode settings and disabled the RadeonPro (back to how I have my game after the latest patch/hotfix) and whilst flying the same mission, everything seemed a lot smoother again, minimal stutters and avg fps in the high 30s.

Don't know what to say really, I wish I could get the same performance increases that roadczar and Kankkis are reporting but it aint happening at my end...well, not when actually flying a mission anyway.

I suspect I am applying Radeonpro correctly as I got the different performance results (flickering/no flickering etc) when trying the different profiles so I think I have done things correctly.

Thanks anyway guys, but it looks like I will just have to wait for official updates for any further improvements on my rig.

Thankfully, I get decent performance with Pseudo mode as is (albeit with some tearing) so i am still having fun with the game.

specs: intel i7 950 @ 3.8, 6Gig 1600 DDR3 Ram, ATI 5970, win 7 64 bit, track ir 4.

Usual In game settings (Psuedo mode): 1920x1200 (Native), Epilspy off, SSAO off, V-sync off, Building amount High, Building textures medium, Textures High (down from original), no AA ..everything else on and maxed.
