Issue after 5850 Crossfired -SC2

Hello all,

I just cross-fired 5850's. I noticed after installing new drivers my Fonts on my 2nd Monitor was blurry. I enabled GPU scaling in CCC to correct this problem. My Native resolution on which i game is 1900x1200 (Acer G24 -native res.), while my 2nd monitor is set to 1920x1080 (Acer S243HL -native res.)

First time i loaded up SC2 the map which i was playing on was only showing the main building and the terrain (units produced, building additional structures, minerals, did not show up as well. I Re-booted the computer and everything was ok (i was thinking maybe i forgot to re-start computer after installation of new drivers). Today I loaded up SC2, and same thing happened but with two patches of minerals showing out of the 8 (again units produced, buildings, etc) did not show. This does not happen all the time, and i can't really pinpoint what causes this or how to re-create it.

I did not have an issue when i had a single 5850.

Does this sound like my video cards or SC2 patch 13 which is very buggy right now?
Can GPU scaling cause this?

Im just lost (again) *awwwww*

I don't have any other game installed on my computer to test either.

hey guys, i've done some researching, if I disable xfire it works fine, anyone else have any other solutions? I feel silly not using the xfire when i have the resources to do so. sigh*

I don't see the point with crossfire on SC2 its extreme overkill. With one you can max out every available setting and with less power comsumption then xfired.

SC2 is still in beta and ATI has yet to release new drivers for the game.

blizzard took their sweet time with SLI & CF support in WoW. I don't see why they would change for SC2 since SLI and CF make up less then 5% of PC gamers. Often support for dual cards comes well after a PC games launches.
