fifa 13 will not run on windows 8.1 but origin works fine i solve fifa problem by using crack and it works fine. if you have genuine fifa you can play it online even with crack
YES!I solved,problem is "Stereo service-NVIDIA Stereoscopic 3D Driver Service" -STOP this and fifa13/origin RUN !!!
all steam games work as well just tried them all last night and bf4 works i am playing the alpha version and all emulators run flawless
