Ok, so I am happily playing SupCom at 2560 x 1600 on my monitor. Then I think, "Hey, I have another 19" Viewsonic (VB191b) that I could add, as SupCom supports dual monitors" So I unhook Xfire, set my main to 1920 x 1200 (main GC) , the secondary to 1280 x 1024 (other GC), and fire up the other monitors. WooHoo ... wait ... SupCom supports dual monitors only in dualhead mode (one GC) not on multiple cards. Ok, I think, I'll just re-enable Xfire and do it that way ... wait ... No dual monitor support when in Xfire mode. Grumble grumble .... no, I don't want to hook up both monitors to one card and leave the other sit there. Fooey.
