I, too, have been running ME3 on Win8 (Preview (all), Public Release, and 8.1) with no issues. I mean literally, NO. ISSUES.
So something is going on with your install/configuration, but Win8.1 isn't the problem. 😕mileysurprised:
I don't know what the issue could be. I have tried downloading Origin from EA's website. I have disabled my anti virus, tried to optimized my graphics using GeForce Experience. All drivers from Nvida have been downloaded. When I click on my shortcut from my desktop or from Origin nothing happens. The first time I installed it however it started to work and I plugged in my headset. There was a roaring sound and the computer froze. No error messages.
If I can't get it to work I guess I'll have to go get a copy and play on a console. What I don't understand is that Star Wars The Old Republic works just fine with this computer.
