6950 xfire w/ low FPS ?

[fourty03]

I am not sure if it's just my setup here or if I did something wrong.

I have been playing crysis 2 for a couple days and I cannot get over 32 average FPS.

I have the details I believe up to advance, and gaming in 5760x1080.
I have an eyefinitey setup with x3 23" monitors.

I have two Sapphire 2gb 6950's with unlock bios running at 880mhz.

Im at one stage in crysis, in which the framerate is constant at 14fps..

the temps seem to be around 54c average when under load for GPU1 and GPU is a little under by ten degrees.

Any suggestions? I believe I also have the ULPS disabled (did via sapphire trixx and the registry).

Please, let me know if any information is needed. This is actually a quite fun learning experience so far.

Its a new(ish) game release, thats a TWIMTBP, and is probably just haveing crossfire issues. Probably a good idea to play with the newest drivers.... apart from that? if it is a crossfire issue,... wait for it to get fixed.

Do you have Catalyst A.I on? Useing newest drivers (newest ATI Catalyst Application Profiles)? Have you installed the latest patch for the game?

*If you have flickering issue, it seems some have had luck useing Bioshock/F.E.A.R profile for cf (with RadeonPro prog).

I used radeon pro (as I saw kcuestag post on another forum) and my fps jumped from 40-60fps to constantly over 100+ fps. I was amazed to see such a huge jump (considering maybe crossfire wasn't working).

**edit:

go to a Crysis2 forum and look around, they probably have more users that know wtf is up... I dont even have Crysis2 myself.

Like Arkadrel said, it's a Crossfire issue. You can see that much in benchmarks of the 6990. Hopefully AMD will release a Hotfix soon to take care of the issue.

thanks for the advice guys!

I did the trick where you rename the game to
"Bioshock" and it got rid of the flickering.

Also, i've read conflicting responses regarding using one crossfire bridge versus two just for a dual GPU setup.. some people say one is good, and some others say they have two connected (both bridges) and saw an improvement..

My sapphires came with a crossfire bridge in each box, and I only have one installed.

I tried the beta 11.3 before it went official<?> and saw a bunch of flickering, then I used the cccCleaner and driver sweep to uninstall them. I went back to the previous one's (11.2?) and had not tried the final release 11.3 . I will try them tomorrow and do a comparison and report back.

Again, Thanks for the help

Use both bridges. That is what AMD recommends on the 6000 series cards. One bridge was recommended for some of the older CF setups.
