I have 2 6870 on Crossfire and i think its having problem with Crysis, its set on medium yet it only hits 30fps, is it crossfire seriously this bad ?

More about : crossfire bad

What do you get with 1 card? What drivers are you using? What CPU and motherboard are you running? What resolution are you playing at? What power supply are you using?

Need a lot more info to help you out...

1 Card = 30-40 fps

2 Cards = 30-35 fps

My drivers are the latest, Catslyst 12.3 and 1.3 CAP 1

CPU Is a AMD Phenom X6 3.2Ghz

Motherboard is a Asrock Deluxe 5

1912x1076 (Playing on this one due to refresh rate bug, doesnt change nothing if played at 1920x1080)

My Power supply is a Corsair GS800

Try out some newer games and see how your crossfire results are. Try some benchmarks like Unigine to see if you get the results you'd expect.

My guess: your Crysis results are limited because
-The game is old
-Your CPU is slow and Crysis is notoriously rough on CPUs just as well as GPUs

BF3 is horrible on crossfire, had to set texture quality to high and disable MSAA, skyrim gets some lags, assassins creed revelations too.

Crysis has been released in 2008 and i Have a 6 Core 3.2Ghz CPU, how can you possible tell me its slow ?

Crysis was released in 2007 and is not well optimized for more than dual core CPUs. So, the fact that you have 6 cores is mostly meaningless. What matters is that they are Phenom II cores (which aren't that great compared to modern Intel architectures) at a relatively slow clock speed, yielding poor performance.

That said, I'd test each GPU individually and see if one of them is faulty. And as I mentioned above, I have read in a few places that Radeon 6xxx series cards below the 6950 can be fussy in crossfire.

Do 3dmark11 or Unigine Heaven give you the Crossfire scaling you'd expect?

Unigine heaven is pretty lightweight... it's completely free and not even 250MB to download: http://unigine.com/products/heaven/download/

It also pretty much doesn't care what CPU you have, so it would be a good test to see if your GPUs themselves are scaling properly.

use msi afterburner to monitor in game if you are even using both GPUs me finks that is not the case.

Along with frames per second Afterburner can also show you the GPU usage of both cards in the onscreen display during gaming, along with many other things. In Crossfire/SLI I believe GPU usage of the two cards should be roughly equal in games that can use it properly.

That is why I suggested OP use it LOL me finks op will only see one GPU present cause thats what the FPS indicate.

I know this is going to sound like a pain, but:
-Run the test with each GPU individually
-Then run the test with the GPUs in crossfire

If your GPUs are both working, then you will get very close scores from each individual run, and something close to double the score (maybe 1.9x) on the crossfire run. If you have problems on one of the individual runs, you have a bad GPU. If you only have problems with the crossfire run, then you have some sort of bad driver or other software/hardware issue. At that point, if it were me, I'd just clean install the OS and try getting things running from scratch.

How do i run each GPU individually

Minimum FPS typically occurs on the very first frame of the demo and (if so) has more to do with your CPU than your GPU. If that is from microstutter, that's some of the worst I've seen... microstutter doesn't usually impact framerate that much - it's usually more of a problem with perception/user experience than actual benchmark reports.

To run each GPU individually:
-Disable Crossfire in CCC
-Run the benchmark
-Switch your GPUs (e.g., move the top card to the bottom slot, bottom card to the top slot)
-Repeat the benchmark with crossfire disabled
-Re-enable crossfire and run the benchmark to get your crossfire results.

Take the bottom card out, run the benchmark. Then take the Top card out, put the bottom card into top slot, then run the benchmark.

If that x6 is a stock clocks it is defiantly bottlenecking the GPUs overclock that unlocked Phenom II x6 and then come back and tell us what happens.

Of course it's a CPU bottleneck OP is running 2x 6870s in CF on a STOCK clocked Phenom II x6 @ 3.2ghz which would be somewhat fine for one 6870 but not two OP NEEDS to OC that CPU of his.

Really?I think you need to research a litttle.My 1100T stock(it is oc'd now to 4.0ghz) doesnt bottleneck my crossfire 6950's(stock or unlocked to 6970's)Both gpu's and cpu running 90-100% in BF3 Ultra settings,1920X1200.

You could go windowed mode to monitor CPU useage in real time when playing a game but then that will force one GPU to shut down even when CF is enabled so like " Sunius " said use task manager to monitor the CPU usage it has a nice history graph that logs CPU usage.

I do believe there may be something up with your crossfire setup, however, 50% usage can be misleading. A lot of older games are designed to only use 1 or 2 cores of your CPU. If it uses 2 cores at 100%, your CPU usage will read 33%. If it uses 3 cores, your usages will read 50%. You need to look at the individual core usage for a little better idea.

Just cause your a fan boy does not mean you have to spread misinformation. FACT 6870 in a Crossfire configuration can and will be bottlenecked by a stock clocked Phenom II x6 whatever CPU

Reload the game. The aircraft carrier has a bug with a massive memory leak. All you can do is reload the game when it does that. It'll happen several times before you finish it, but to help, turn off aero and the more memory you have, the longer it takes to hit you.
