Crysis 64bit issue

I am having what seems to be the common problem of trying to run the 64 bit version of crysis and getting a black screen then crash right after launching the game. I have done a lot of searching and did a few of the suggestions like uninstalling the Nvidia Network Access Manager, changed my settings to force vsync both on and off, and set single display performance mode. I have tried both exes in the 64bin file, launching from the vista game explorer and my drivers are up to date. Also like others the 32bit version works fine. I have also reinstalled the game.

Thanks for any help.

Had the same problem ... fixed it by running Crysis in DX9 mode rather than DX10 (go to Games, right-click on Crysis and select 'PlayDX9')

Have you tried disabling SLI to try and isolate the problem?

I had the same problem and read on here to remove the Nvidia Network Manager software and lo and behold this fixed the problem for me.

Nah disabling sli doesnt do anything not that I would want it disabled in the first place

As I stated in my original post I already uninstalled network manager.

Alright I got it working though I am not 100% sure how. Biggest thing I tried today was dl this Download details: DirectX Redist (March 2008) . Didnt work at first then I realized I still had compatability mode on and turned that off then it worked.

well it mostly always helps to have the latest version of drivers and software

glad to hear you got it working
