Yeah I saw that, it's pretty much exactly what i'm looking for, although I'd rather have the FoV on one screen (I like having a second window open on the side). I'm wondering though if your particular performance hit is mainly due to having to render 3 hi-resolution screens (6 simultaneous frames in buffer on top of whatever render passes are needed per scene, which is at least 2 for UI and environment, not counting any extra stuff and post-process effects you might have toggled on, ie; ambient occlusion, real-time shadows etc).
