Finally got my Eyefinity 3x1 setup and working. Even got a mod that puts the HUD back on the center screen (hopefully that works on our server, haven't tested yet). I'll post a pic soon. First run through a single player map I got a little dizzy. Its really disorenting at first. The side screens stretch the image so that if you stare solely at the center, it simulates perefer... preif.... side vision.
