After pre-ording Crysis 3 I have had a great time with no problems (both MP &SP) on the PC
I installed Crysis 1 (off origin) entire game just crashes even just in the menus after changing settings or creating a new profile. I tried loading a LAN game and it just crashes before it loads in.
I tried running as admin, and in compatibilty still crashes.

I was wonder how to fix this as I'd like to play the campaign of Crysis 1
Any help is welcome
Thanks
