Hi,  
 
Currently with the system below I get about 40fps on medium but high is completely unplayable. Does anyone know if im doing anything wrong? I currently have all the latest drivers and the latest crysis patches, including 1.2.1. Does anyone have any idea?

you may be experiencing a similar bottleneeck, probably the one I am, if you solve your problem, let me know.

Post all your specs.  If it's worth under $2000 then there ya go.  Bump it to $3000 and you can almost run it all on high.
 
Not even a tri-SLI (3 vid cards at $600 each) and the fastest processor can run Crysis on all high settings.
 
Edit:  I see your specs, it ain't enough.  
 
And TT water cooling?  Ack......

Nobody can run Crysis on extreme settings yet, not until either NVIDIA or ATI release a monster card that we're all hoping for.
 
I can only get 30FPS on medium settings and at least 20FPS on high without all that anti aliasing on my 640MB GTS at 1680x1050 which is kinda sad really.

With my system, I get like 25-30 fps on high (at most times) at 1680x1050. What resolution are you trying to play at? Crysis is very playable at 30 fps unlike most shooters. It's not as nice as 60+ obviously, but it will do.

I can run it at high everything (XP SP2 32-bit on the retail Crysis patch with 174.20 ForceWare) with 8xAA Q and 8xAF at about 20-30FPS @ 1280x1024.
I'll have a play with some of the settings and see whats the maximum I can get out of it!

He said High, not Very High. My system is perfectly playable on a mixture of high and very high with my two 8800GT's with Vista. I would suggest manually adjusting each setting rather than just going globally from Medium to High. Some settings kill your performance more than others, change some settings and run a benchmark and see how it does.  Things like Motion Blur take a huge amount of GPU power.

"OMG I cant run Crysis on high!"  
 
Seriously.  Why does everyone have themselves all worked up because one game, which was written for hardware that will be out a year from now, doesn't run at 60 fps on hi settings.  Not that long ago, this game would would have been panned just for the simple fact it wont run worth a crap on anything but the best hardware and lots of it.  Im not saying its a bad game, I own it, I like it and the reviews of it speak for themselves.  But seriously, is 98% of the public going to build a $3k gaming PC just to play one game?  Unlikely....  Its a poor measuring stick for hardware.  I personally think if the code was better written, it wouldn't be such a resource pig that it is.

OP has a G92GTS SLI system.  He should be able to play very high long as it's not over 1280x1024 and no AA.

I'm only on a 8800gs and I can play high just fine.  38fps average @ 1440x900.  65fps in medium.

What a mind splinter Crysis has turned into.  People freak out because their settings say medium but take in no consideration that the game looks brilliant at those settings.  Crysis is now more of a benchmark than it is a game.  
 
I am curious to see how Far Cry 2 is handled regarding what settings are available.  

lower the settings that are cpu limited such as  physics, particles i belive is mostly done on the cpu, and maybe post processing, im not exactly sure, but your cpu is a bottleneck for the gpus even at that res, look at tri and quad sli bench's, the cpu is bottleneck at 1920x1200 very high on a 3ghz quad. lower cpu depending settings and raise gpu dependent
 
I can play mostly very high with shaders+a few other settings at high on a single gtx @ 660/1520/1070 @ 1680x1050, id rather run those settings then all high and a few med @ 1920x1080 or 1920x1200.

At what resolution are you trying to run and what AA settings?

I have an e6750 @ 3.6, and 2x 8800 GTXs, and play on high at 1680x 1050, with 8x AA on, and fraps stays near 40, down to 34-36 on the ice/dome series.
 
Still get the widescreen look, but cannot stay on high at my 28" native 1920x1200 res.
 
Cut your res down to 1680x1050 and rock on!

Join the club op.

If he can get 40fps in medium and unplayable on high setting then he is gpu bottlenecked not cpu bottleneck.

There is something wrong with his system.

TO OP: You should uninstall your drivers and install the latest 174.74 drivers.  This drivers improved my crysis performance by 10%.

He could also try to run in DX9 mode ... if he doesn't see any difference who cares.

This config works very well on my stock 2900pro, in windows xp,
 
1400x900, first 3 levels 30fps+ average:
 
(havent got any further in the game yet, cos im about 1000 miles away from my pc)
 
Texture quality - high
Objects quality - high
Shadows quality - MEDIUM
Physics quality - high
Shaders quality - high
 
Volumetric effects quality - MEDIUM
Game effects quality - MEDIUM
Postprocessing quality - MEDIUM
Particles quality - MEDIUM
Water quality - high
Sound quality - high
 
The rest of my system is fairly mid-range.  e6300 oc'd to 2.6ghz, 2gb ddr2-800.  When I game I use 'msconfig' from the run dialog and chop out what isn't needed for gaming, bringing me down to about 19 processes for when I restart and the changes are applied.  On a 1gb system like I had for years thats an essential thing to do, and it can even have a tangible effect on a 2gb system.
 
A 640mb gts should manage these settings at 1600x1200 for most of the game, if not the whole thing.  With the latest patches and drivers it should just about do it.  A mild oc would be a good idea too.  The 174 forceware makes some signifigant gains in Crysis, and when nvidia finally decides to incorporate the G80 chips into a newer driver, you could see some real improvement in game fps.  
 
 

With my new 1024 GTS I get between 20-30 FPS on very high at 1280x1024. Just played it all the way through and the lowest it got was 12. Though I do have it overclocked quite a bit.

It seems to me that crysis is more of a benchmarking tool than a game.. which makes sense cause it kinda sucks as an actual game..

the op's info suggests he's running 1900x1200, which pretty much nobody can run on high, so that's one reason.  the other issue is probably his cpu, which is no slouch, but no match for a core2.  it's most likely gonna bottleneck the two gts's at some point.
