Crysis FPS drops when looking at something in the distance and zoomed

2 x MSI Twin Frozr III 6950 2 GB
i5 2500k @ 4.2 Ghz
Antec - TP 750
128 Crucial SSD
4 GB Corsair XMS3

I have compared notes with two other people who tested in the same exact areas. My GPUS were beaten by a 5770 CF setup and a 480 SLI setup.

480 SLI results
Not zoomed

56 FPS @ 76% usage

Zoomed

57 FPS @ 94% usage


5770 CF results
Not zoomed

71 FPS @ 74% usage

Zoomed

82 FPS @ 99% usage

The 5570 user wasn't in the same exact spot but my results there were

45 FPS @ 60% usage and zoomed in was slightly worse. His FPS dropped when he zoomed but quickly recorrected to 99% usage to bump his FPS back up. Mine do not....

Both using the exact same settings? one of your HD6950's should beat his/her HD5770's CF.

You haven't got V-Sync on have you?

May also be worth checking GPU-Z to make sure that your cards are running in CF and at the right clock speeds. Also check that here running at atleast x8.

Temps Ok? (CPU and GPU's)

Download and run FurMark. Look at the temps and post the highest temp in an hour run through, if you start to artifact (And your at stock clocks) then its probably the card.

Just making sure, how old is the PSU?

Make sure V-Sync is disabled, and that your running at the same settings. Also check GPU-Z to make sure that your cards are registering crossfire, and right clock speeds. Also make sure that the 'Bus Interface' is at least @x8. If it says @ x4 then its your motherboard supporting really bad crossfire.

PSU is brand new.

V Sync is disabled

Cards are indeed working crossfire and at the right clock speeds. I also checked and its not a power play issue with them downclocking to 2d.

Bus interface - PCI Express 2.0 x 16 @ x8 2.0

My cards actually can reach 99% each. They usually rock pretty hard like that when Im fighting through the jungle in a closer enviroment. Its normally when I reach open areas they plummet BADLY. REAL BAD.

Im honestly thinking of sending them back. $600 is alot of cash for this kind of performance.

My CPU as a whole reached maybe 55% usage using task manager to measure.

Core 4 had some spikes that were high around 90 and quite a few around 80. Temperatures reached a max of 47. Ram usage was around 70%.

It seems when the tris counter goes UP, my GPUs just start taking it easy.

Run some standard benchmarks with known settings.

It is inconceivable that a pair of 6950s is beaten by lowly 5770s, short of a glitched/botched driver install....

Actually that was an error on my part. They are 5870s. Clocked @ 1000 mhz.

That heaven benchmark looks like both cards are running full throttle. The only time they dropped to 80% was during a certain scene or two.

Farcry 2 stays around 70% usage and gets me anywhere from 100-140 FPS.

Well that changes everything, 2 x HD5870's at 1000Mhz core will be as good if not better your HD6950's. I would put this down to driver issue's as your other results seem fine.

I have installed 11.6 CCC and the CAP several times over after using driver sweeper and uninstalling ATI Install Manager express which deletes everything. Driver Sweeper nabs the few remaining files.

Then I reboot and install CCC 11.6 instantly.

I have also tried 11.5.

What can I do? I have tested BOTH cards separately in my first PCI-E slot and they work exactly the same. Aiming at the gas pumps gets me 38 FPS. Shooting them drops it to 32 and rises back up to 35 with the flames and smoke.

When I installed both cards with CF enabled, aiming at the gas pumps brings the FPS to 34 ish. Shooting the pump drops it to 28 and brings it back up to 31.

Advice?

Your Heaven benchmark results are normal and quite good.

You should check out other benchmarks. Crysis can and does take a lot of resources. 480's in SLI is slightly more powerful, but a lot hotter and noisier. 5870's in CF are also very close to the same.

In a lot of games, not being in the same exact spot does make notable differences are you sure you are close enough to the same location to be considered accurate?

One other issue that plagues Crysis is that it has a memory leak. The longer you play, the slower the game becomes. It's highly advisable to always turn off Aero before you start a session to prologue how long it takes before the memory leak gets you. Having 4GB's of ram is going to make this a big issue for you.

Yes, we were standing in the same spot. Its ONLY when open areas enter my view.

Crysis 2 doesn't drop below 80% usage in the first few areas. But that game is more enclosed.

Metro benchmark had 1 card @ 44 FPS and 2 cards @ 71

Another thing is, the memory leak can't be affecting me because I just boot the game up and run about 10 seconds to the spot. Once I look towards the spot I get the FPS drop. I can turn around and face the mountain and get 90+ FPS. Usage climbs in that situation.
