I don't get any FPS gains using newer drivers from ATI. I have to use 10.5 in order to get the frames i should. Installed all drivers from 10.6-11.1 and got worst performance in Crossfire. Yes i did Download Application Profiles...Still the same results
My Mobo Is Ga-790XTA-UD4.
4 Gb DDR3.AMD
Phenom 945 3.0Ghz.
Ultra 750 psu.
Only play BC2.
Both Cards show 98+ usage(on 10.5 drivers).
running at 73*C.
1920 X 1080p
I do have to add that one Card is XFX 5770(850 Mhz, 1200Mhz) and other is MSI Hawk 5770 (875Mhz, 1200Mhz). I did Downclock it to match the XFX.
Was set to standard just today i switched it to Advanced and 10 more frames.... (On 10.5 Drivers)
I want to be able to utilize the newer drivers.....help?
More about :reverted back ati drivers crossfire setup gains
New drivers are released to add support for new games and may contain fixes for known issue's, Don't expect to gain performance via new drivers, The HD5770's have been out for awhile now, usually the first few drivers that are released after a new card comes out will improve performance, but after that performance will stay roughly the same.
When I had Crossfire HD5850's I found 10.4's the most stable and gave the best performance, even compared to later drivers like 10.9.
In that case it seems like CF isn't working at all with newer drivers for you, I'd recommend removing all ATI drivers, then enter safe mode and run driver sweeper to completely clean out any ATI driver related software/registery entries, then try installing the latest driver which should be 11.1, double check that CF is enabled.
I've had crossfired 4870's for a long time now and the best version I have used is the 10.5's. I have tried 10.6-10.12 and they all dropped my performance by about half. Every time I would revert back to 10.5 and watch my fps go up up.
I have upgraded cpu sockets since orginally testing 10.5-10.12, but with testing 10.5 against 10.12 I received similar results so I figured I wouldnt investigate much farther since 10.5 worked so well, as you will see below. Tested with Battlefield Bad Company 2 at 1920 X 1200, High Settings, 2x AA, 16x AS, NO HBAO. (4x AA is certainly playable, its just not as smooth as 2x AA is.)
I hope this help some, as its not the same card as you, its still a ATi - *clears throat* I mean AMD - driver experience story, and crossfire.
PS- you have to have Catalyst AI set to Advanced for Xfire to work properly.
For the Xfire profiles I used the last ATi branded ones, since to me it was logical that since I had 4870's I should stick with the ATi branded ones rather then going as far as the newer AMD styled drivers. All in my head? maybe, but I'm happy with the results, wish AA could be at 8x, but I dont even know if any ATi cards are able to go to 8x.
Btw - I mostly only play BFBC2/V too(another reason for this post -long term AMD driver experience with xfire and BFBC2.) With side dishes of L4D2, Napoleon Total War, Civ5, SC2.
