Here is an intresting thing I have just found out. If you have 1 or 2 monitors plugged in that are not in use by MWLL, you STILL take a performance hit....A large perfromance hit....
1 screen nothing else plugged in my hanger fps at the top is 150...Plug in another monitor that is doing NOTHING, just displaying desktop, and my FPS is now 100. Outside the hanger my FPS goes from 80, to 65...Thats a hell of a drop of a FPS for just displaying desktop on another screen. Adding another screen to that, doesn't seem to lower FPS any lower, I think surround mode does something but I still take a hit compaired to one screen by itself.
Anyone else notice any drop in FPS just by having two displays, or even three? It seems bizare that showing desktop on a spare monitor would rape my FPS by so much expecially with SLI GTX 580.
So I guess I might have to unplug two of my monitors every time I want to play MWLL...Man that's going to get annoying!
*Edit* Oh and I get FAR less stuttering and FAR less FPS drops with just one single screen plugged in. It's like my miricle cure for all my MWLL FPS problems. Well ok zooming still ruins my FPS.
