Same thing as StarCraft II, people who were using EyeFinity would get an advantage over those who didn't, and so the QQing would ensue. Instead they just decided to cut it.
I see their point, its literally a lot more useful in a top down fixed cam RPG since you can see enemies coming off screen that you wouldn't normally, it's kind of a big deal. But it just demonstrates that their game design doesn't apply cleanly to the modern world of PC gaming. I mean hello, add a cam that can move around and a minimap ... 90% solved. The whole use the mouse click to move around is very 90s, players should have an option to use WASD to move around and mouse for camera.
Optimization reason is bollocks. Companies should really stop lying about their reasons not to support Eyefinity.
Oh really then how come they allow people with better GPU's to play the game with faster framerate, and people to buy all the Starcraft 2 (tm) razer keyboards with macros on them
And how come they allow people just buy their Gear for real money, so a person who spends a lot of $$ will get competative advantage?
