which drivers for CF 6850's?

post #1 of 16
Thread Starter 
k sig rig in the machine under quesiton here...this is the scenario...ran the driver disk that came w/ my vid cards...worked fine, upgraded to latest catalyst and i got inconsistant preformance...rolled back...worked fine...while experiencing inconsistant preformance here is the fluctuation in my furmark benchmark testing: 3300-8100 (1920x1080 fullscreen 60 sec multi GPU)...quite a difference...anyway through other reasons involving raid, i just reformatted yesterday, i downloaded the latest catalyst without running the CD packaged with my cards, installed...setup eyefinity...and back to my inconsistant preformance...to give you an idea of what the issue is....i restart my PC run furmark benchmark to make sure GPU's are functioning properly, and average 127 FPS...loaded bad company 2 and my FPS drops to ****...close game, re-run furmark and my FPS drops to an average of about 45...restart my PC...run furmark...127 FPS...its ****in irritating and i'm about to just chalk it all up to the peice of **** that is catalyst...your thoughts?

update: just uninstalled latest catalyst and rolled back to the catalyst that came w/ my cards....10.10 w/ driver packaging version 8.782-100930m and i'm still having the EXACT same preformance fluctuations...soon as i open a game my preformance tanks and stays tanked until the CPU is reset

You're not alone. Experiencing the same exact problem. Doubt there is much to do about it but to wait until some updated drivers get released. 6900 series aren't even 3 months old yet so there is still a while to go before everything is buffed out unfortunately.

Edit: Sorry I though you were talking about the 6900's but it seems like its 6000 family drivers in general that are having major issues.

It's been like this all the time, and just from ATi's side only either (nVidia does the same thing). They rush out hardware before the software is fully optimized to grab the cash and we sit there on the side line, twiddling our thumbs. Waiting for them to drag out some decent drivers.

One of the biggest flaws about being an early adopter.

P.S. In fact I remember having the nVidia 8800 Ultra and for 6 solid months getting crappy frames in a lot of games (and some not even being able to run at ALL!)

true enough, i guess i figured the 6850's had been out for awhile now so they would have the software backing, i also heard the 6xxx series scaled awesome relative to the 5xxx so that was definately a selling point...is there an older driver that i can run atleast temporarily to make BFBC2 playable?

I honestly wouldn't have a clue which version would be best for the 6850's. Have you tried disabling crossfire in CCC? It sometimes helps for me in certain games.

no i havent...i've come to the conclusion that its not a crossfire issue, i've tested multi GPU and when it is slow, the single card test is also slow so that tells me its not a scaling issue

Catalyst 10.10 wasn't really optimized but this driver was showing maximum performance, but from the other side picture quality wasn't good enough,
Catalyst 10.12 fix that issue but performance drop a lot, also I've heard that crossfire in some games really a big mess.
try 10.12 with disabled CF

well when it runs like its supposed too i run bfbc2 on max settings @ 5760x1080 and i'd estimate about 100 FPS...when it doesnt run like its supposed to i turn down to medium to get somewhere along the lines of 20 FPS...so crossfire works/scales just fine..."when the driver is working"

Why does everyone have such a hard time with drivers in crossfire? I load one card, install drivers, load second card in slot it will be in and remove first card, reinstall the drivers. Then I install both cards, bridge and power, then reboot and bam crossfire up. Thats with 11.1 drivers as well and with cards flashed.
