ATM it looks like everyone's having similar problems with crossfire. Just upgraded the drivers of my two 7850s to 12.7 beta and it looks like one card is doing worse. So decided to finally do some benchmarks and wondering what everyone thought. And btw sorry of this sounds like I'm moaning :D. Just kind of worried that I have one or two faulty cards as other people say they get 44 FPS on the heaven benchmark with one card and I only get 52 with two cards? :S so I'm a bit confused.

Batman Arkham Asylum Settings for benchmark (no vsync)

Benchmark Results for graphics card 1

Batman Arkham Asylum with VSync- graphics card 1
Settings- http://imageshack.us/photo/my-images/833/batmansettingsvs.jpg/
Result- http://imageshack.us/photo/my-images/228/batmansingle.jpg/

Graphics card 2 for batman with vsync enabled comes in at :
51 min
63 max
59 avg

Which is similar to graphics card 1.


I then decided to test the graphics cards individually using heaven.

In crossfire however the score was- http://imageshack.us/photo/my-images/69/heavenxfirenone.jpg/ which isnt as big of an increase as I thought'd be.

Does this seem right or is it completely wrong? Or am I just being too paranoid about the cards being faulty? ;D sorry for the long post and thanks for any help.
 
Try using the same settings on Heaven for a comparison, you're using "Extreme" tesselation, 16x Af and no AA (second card 8xAA)...so even for a comparison between the two cards, you're using different settings lmao :P


With those settings, you're bound to get a lot lower score...(my neck hurts reading the scores!)

Settings we use are here: http://forums.overclockers.co.uk/showthread.php?t=18386056

The crossfire score is near 100% scaling btw, so working fine (using your second card settings...damn i'm confused!)

EDIT: You're also using the older Heaven 2.5. Heaven 3.0 gives higher scores.
 
-_- wow I fail...
Thanks for the help though and sorry about the pictures ;D
Will defo try out 3.0 and I'll test the cards using the same settings as well :)
Hopefully everything works out okay and its just me being an idiot
 
I was kinda wondering why the scores were so low then noticed that crossfire was near 100% scaling and turned my head 90 degrees and saw tessellation on extreme :)

For the record I just ran 3.0 with the settings you were running on my 7850 and got almost identical results so your results are fine :) Run it with the approved settings and it will be in the 50s (for a single card I mean)
 
:| damn why didn't I think of turning off vsync?
And I thought you had to benchmark at the highest settings- isn't that the whole point?
I'm probably wrong though.
I'll run the benchmark at those settings tommorow and get back to you all :D

I benchmark to either compare with other people, or to compare against my old hardware....the only way to make reasonable conclusions is by using the same settings throughout...

So you *can* use highest settings, but that would limit your ability to compare.

I get that but then surely the best settings for everyone to use would be the higher settings because they push your pcs graphics and CPU more? I dunno, in my head that makes more sense ;)

You choose settings that are high enough to push the cards, but that everyone is capable of running. If you put the settings too high, lots of people will pass on running them, because their cards struggle too much.

Benchmarks mean nothing, unless you have something to compare them to. So choose settings that other people use, so you can see how your setup compares.
 
The scores look fine. Could do with an over clock on the cards though, those cards are begging for it. Also you should change your misleading thread title, you don't have any crossfire problems by the sound of things.
