Ok ive been messing with this for about 9 hours now and i've narrowed it down to DX11 causing the crashing. I can play in DX9 all day, but 5-10 minutes with dx11 enabled game stops responding. Any ideas?

my setup:
evga gtx 570 sli SC - 275.5 drivers
i7 2600k @ 3.4
corsair vengeance 2 x 4gb 1600 - 9/9/9/24
zalman 850w psu
win 7 x64
(same setup before 1.9 patch and dx11 and all worked fine)

Ive tried reinstalling game/drivers, testing each card independently, reset cards in mobo, I'm sure ive narrowed it down to only when DX11 is enabled is when the crashing occurs. Thanks for your help!

EDIT: It seems the problem is because Crysis 2 is more of a beast than we thought. I've played at least 4 hours now with no slowdowns or crashes. The solution is:

1. Downclock your GPU to the stock nvidia/amd recommended settings (for example - I have EVGA gtx570 SC sli which is factory overclocked - I went to nvidia.com and found the stock clock speeds for a stock gtx570 and applied using MSI - working like a charm now

2. If you don't want to Downclock then increase your voltage (careful with this as it may cause problems if you don't know what you're doing)

I'm getting the same exact problem and my computer is basically the same, cept i have an i5.

My specs are:

Video card - VGA EVGA|012-P3-1572-AR GTX570 R
Processor - CPU INTEL|CORE I5 2500 3.3G 6M R
Ram - MEM 4Gx2|CORSAIR CMZ8GX3M2A1866C9

HDD - HD 1T|SEAGATE 7K ST31000528AS OEM
PS - PSU CORSAIR|CMPSU-750TX 750W RT

Computer is not even a month old. Game ran EXCELLENT before this patch, now it crashes every time. I click resume game, take about 4 steps and it crashes. Tried a multiplayer game, same thing. Tried a new game, same thing.

I'm getting same problem.

+ I tried on nVIDIA Driver Version 270.61 but it crashed too. Now I just give up guess i have to wait for patch or something.

same problem, gamne crashes and strange sound loop bug, black screen, i'm gonna try upping cPU voltage, i've tried everything MP game drops FPS violently and stutters.
gtx 580
i5 760 @3.8

I'm getting crashing too. I can play the game for about a minute max and then it crahses hard. I'm running Nvidia surround 5760x1080 or single screen 1920x1080. The higher the resolution the faster it crashes. I tried tons of stuff, it's the patch, no doubt in my mind. I'm also using the high res. texture pack.

System specs:
Intel Core I7 980x 4.4 Ghz

LETS try upping the GPU's voltage!! I'm at 1.075 with 120MHz extra on the GPU core now.

I think its a HDD issue. I can play the game fine, but once i exit my HDD is on the fritz. and my computer goes VERY slow. maybe you HDD is going on the fritz in game then crashing. We have to wait for the game to become more optimized.

It does need optimized, if a ￡400 GPU can't handle maxing a game out, something's rotting in Denmark ...
SandKing i got a lovely new 500GB HDD, it's a good un' i gotta start up MP and give new volts a go ...

Its a software thing that puts the HDD to the fritz, you physical HDD is most likley fine. And yea my 6990 drops to 15FPS for no reason what so ever. i could stare at the ground and it will drop.

Ok I think i might have fixed it - just played for an hour all max dx11 and no freezes - i gotta go to bed but someone else try this to confirm it works

The fix:
I have evga gtx 570 SC (797/1594/1950) in sli - i down clocked them to the stock nvidia settings using msi (732/1464/1900) - and has been running like a 16 year olds ass so far! (very smooth)

@SLI anything work with increasing voltage? - as i think this problem is all in the gpu's - so much for paying extra for a SC version lol

Yes, it's something to do with all your overclocks being unstable under the extreme load crysis 2 is putting on it now. Your PC has never been stressed this hard before, every component at the same time. Lower your overclocks or increase voltage to fix your crashes.

likewise, i'm getting the same problem. game loads up but after a minute or two the frames drastically drop then it becomes a slide show then the screen goes black. tried using beta 275.5 drivers then gradually rolled down to 266s and nothing. also, i killed the oc on my cpu to see it that would help and nothing.

I MANAGED TO SORT IT,

smooth gameplay plus no crashes.
Soultion, keep VRAM at stock, OC GPU and UP GPU VOLTAGE,
I'm 120Mhz over stock on 1.075 Volts and it's as smooth as hell, tweaked post processing with game.cfg and shadows on extreme, how's that?
:P

My GPU and CPU is overclocked ^_^ GO MY EFFICIENT OVERCLOCKING! ^_^

Got the same proble too... game crashes every time when I'll reach the surface
after escaping the sinking vessel. I'm using the DX11 & High Resolution pack.
Game is running like a dream, but then it bites the dust!
Music is still playing, screen freezes and then goes black and next stop is desktop.

nVidia driver is 275.33 and Windows is updated.

yup i think the solution is downclocking. I did what DrMilzie did and My crysis2 work just fine. Try this guys

The 580 trick was keep VRAM at stock, OC the GPU by 120MHz, and up the voltage to 1.075 which i'll maybe up more but it's at 73C.

well i'm actually running the game fine now. i've noticed many of you have factory overclocked cards. i went back to stock settings on my card; i'm running a 570gtx oc edition. i have the game completely maxed out, everything on ultra...high res textures enabled etc...tessellation and so on... ppl have mentioned a performance hit and i've noticed it too but i'm avg 40-60 now compared to 60 constant before. this was expected though with hi-res textures and tessellation being integrated. try to go to reference stock speeds on your cards to see if this resolves issues for you...it did for me. cpu overclock didn't matter as i went back up to 4.2 and still runs fine.

lol Crysis 2 is childs play compared to the applications i use to stress my card.

SAME ISSUE ON A intel i5 750, crash black screen.

Hm so some now wonder when their GPU are under heavy load, that sometime Overclocking is not stable in every Game.

I have exactly the same problem, but my GPU is at stock frequencies...
My specs:
CPU: Intel Core i7 930 2.8GHz (Bloomfield)
RAM: 2*2GB DDR 3 Corsair XMS3
Motherboard: Gigabyte GA-X58-USB3
Power supply: 750W Thermaltake EVO_Blue
OS: Microsoft Windows 7 6.1.7601
GPU: Nvidia ENGTX 570 DirectCU II Asus
Storage: WD Caviar Green IntelliPower 2 TB

What the hell why cant i play in dx 11?

i have the same problem, and tried to lower the factory-oced gtx570 to stock frequency and ended up with locating xxxx bytes memory error

I'm definitely running it on x64 windows 7

Welcome to hell, nVidia 500 series card owners.
Problem of that kind is a well known issue of 500 series video card. http://forums.nvidia.com/index.php?showtopic=192020
I bought my Gig 560 OC about 3 month ago and didn't experience any problems since. Until now...
I've played many times and for long Crysis 2 (DirectX 9) and there wasn't any kind of glitches, errors, hangs...anything bad. But after Crysis 2 gone DirectX 11 i began to feel little frustrated be cuz of driver-restoring error (windows message like "Display driver stopped responding and has stopped. Display driver NVIDIA Windows Kernel Mode Driver, Version 2XX.XX stopped responding and has successfully recovered") came over me. It is strange that i've played on DirectX 11 settings for 3 hours in one piece without any inconveniences. But next day i got restoring-driver-crap after 30 mins of gameplay. I believe that there is NO time dependence. It may take 3 hours to get error or a half an hour.
I dunno at this time what to do. People says that downclocking is a helpfull thing, or maybe increasing core voltage will give a shot. Dunno, dunno...lol

PS - And there is one more game that keeps my 560 ti go bad. F.3.A.R. And again Dx 11 settings. And again no exact time when error to expect. For example. I've been in game for an hour or more and there is nothing, but next time when i decided to play F.3.A.R. i got driver crash after of 30 min. of game.

These are the exact errors I got yesterday trying to get the dx11 content to run. As mentioned I went through the last few drivers nvidia rolled out. Clean installs and finally ended on 275.50 beta drivers. But still had no luck...got the kernel error and so forth. Finally downclocked my 570gtx to stock settings for core clock, sharer clock AND memory clock and now the game runs without error like it should've in the first place. Again nothing worked until clocking my gpu down to stock settings.
