ALright, so i got this 1.9 patch to install my dx11 upgrade.
after installing the 1.9 patch the game WORKED FINE.
but after installing the dx11 the game starts for a few seconds and the 'Crysis 2 has stopped working'.
and if i re-install the game i might have probably exceeded my serial code limit
Either i need a way to fix the dx11 thing or a solution to the serial code limit.

First.. did you "DeAuth" before uninstalling? If so and you've exceed your allowed installs, then "email EA support", they will extend your allowed installations. I exceeded mine with Crysis Warhead / Wars and emailed EA, the very next day they extended my amount of allowed installations.

Oh yeah.. if you want help w/ your Dx11 problems, you are going to have to get a little more detailed, like your PC setup (e.g: graphics card, driver version, etc..), Windows version & edition (e.g: Windows 7 x64 bit), etc.. It could be related to many different things. Have you tried installing the dx11 patch again (I believe it will allow you to install over existing install), do you have the Hi-Res pack installed also? Have you tried different "Graphics Drivers"?

"Usually" (not always, but usually) when you get " xxxxxxx has stopped responding" (xxxxxxx = game affected) that has something to do with a graphics driver, you may need a different driver.. sometime it happens when you overclock your graphics card too. I am guessing by the error msg, you are running either Vista or Win7. Easiest thing to do is.. try another graphics driver first. Also, if you can, look in your event viewer and see if there is a more detailed reason for why it stopped responding.

these are my pc specs:
Windows 7 Enterprise 32bit
NVIDIA Geforce 210 ( just updated my driver last night)
Intel pentium dual core E2180
2 GB RAM

Well.. think I found your problem, though I'm not "positive" .. however, the nVidia Geforce 210 "is not" equipped to handle Crysis 2 in directX 11 mode, I'm actually surprise you could play it in directX 9 mode. That is a very low-end graphics card. The Geforce 210 has a "memory interface width" of 64 bits .. basically to make that easy to understand, the graphics memory does NOT have enough bandwidth to handle such graphics. The "memory bandwidth" of your Geforce 210 is 8.0 mb/sec .. that is EXTREMELY LOW. For example, my Geforce GTX 465 has memory bandwith of 112.8 mb/sec, that is 14 times more than yours, and my graphics card would be considered a mid-ranged graphics card for Crysis 2. Also, it only has 16 shader cores (cuda cores), mine for example has 448 shader cores (cuda cores), that is 28 times more than yours.. I can go on, but it might just hurt your feelings.

Besides, the "Geforce 210" does NOT support "directX 11" anyway, they support "directX 10" and some "directX 10.1" .. while you might see some improvements with a directX 10 graphics card versus directX 9, you still will not get the full range of effects with that card.

I hate to say it, but I don't think your system has enough system requirements to run "Crysis 2" in directX 11 mode, even on low quality settings. You have a 2.0 ghz dual core processor, 2048 mb of memory, a slow graphics card, and a 32 bit operating system.

My advice to you is >> Give up trying to play "DirectX 11 Mode" until you ATLEAST upgrade that graphics card. It just does not have what it takes to handle Crysis 2 in directX 11 mode. Sorry.. I'm sure that is not what you wanted to hear, but it's just pure facts, that card simply can't run Crysis 2 in directX 11 mode.

Now.. if you do not have alot of money you can spend on a "new graphics card", which is surely what you need, then start looking @ the mid-range GTX 400 series or GTX 500 series .. they are not real expensive. You can get a new "nVidia (Galaxy) GTX 465" for $129.99 or a "nVidia (eVGA) GTX 465" for $144.99 @ newegg.com... or you can go for a "nVidia GTX 460" starting @ $149.99 up to $209.99. If you get a "GTX 460" though, look @ the specs carefully, they have 2 different types, one has 192 bit memory interface width and the other 256 bit memory interface width .. you want the "256 bit memory interface width" type, because it has more available memory bandwidth. The GTX 460's have 336 shader core (cuda cores), which is 21 times more than your current Geforce's.

You can also go for a "nVidia GTX 560 Ti" .. they are a little higher starting @ around $189.99 to $259.99, they also have 256 bit memory interface width... once again, there are "two different" GTX 560's, the GTX 560 and GTX 560 Ti .. though either one should run Crysis 2 decently, but the "Ti" edition is slightly faster.

Now.. if you have the money to get a nice graphics card, then I suggest you do some shopping and pickout what you want. First though, it you go with the "GTX 400 series", get atleast the GTX 460 (w/ 256 bit memory interface width) or if you go with the "GTX 500 series" get atleast the GTX 560. The GTX 570 is a great graphics card too and is faster than the GTX 560 Ti.

If you have a computer made my HP, Dell, etc.. make sure you get the dimensions of the graphics card so you can see if it will fit in your PC case. So, to sum it all up and depending on what you can spend....

** First, Upgrade graphics card first...
** Second, Get a little more system memory too ( 3072 mb, since you use a 32 bit operating system)
** Third, Maybe upgrade your processor to something a little faster (find out what your motherboard supports)
** Fourth, None of the above and just play Crysis 2 in directX 9 mode.
** Fifth, purchase an entire new system that has a good graphics card, decent amount of memory, fast processor, and x64 bit operating system, of course if you have the money, then this option truely should be FIRST.

I know it's probably NOT what you wanted to hear, but you are NOT going to get that Geforce 210 to play Crysis 2 in DirectX 11 mode.

whoa..
that explains why the game is laggy at my native resolution ( 1366x768)
anyway thanks for your help man. really appreciate it
