Swapping game clients between monitors that aren't driven by the same video card is going to give worse framerates
than if they were using their native monitor/gpu and I'm almost positive that this is a limitation of Microsoft Windows. For
example, you've got GameWindow01 powered by GPU01 on Monitor01 and GameWindow02 powered by GPU02 on
Monitor02. Now, if GameWindow02 swaps over to Monitor01 it's no longer being rendered by GPU02 because GPU02 can't
do anything to Monitor01 since it's not hooked up to it; therefore, GameWindow02 is now being rendered by software
instead of hardware which doesn't give the same framerates.

Also, the GTX 260 doesn't technically support DX11, it just emulates it.
i have 2 cards, non sli, mon1 to main and mon2/card2 to slaves. in wow i have the primary display on slaves set to mon2. i do cross monitor switching and there is sometimes a bit of delay but for the most part no perf dercrease or fps loss other than that initial second. its important though that you have your clients set to the right default monitor. it kinda looks weird when you launch and the slave clients start on 2nd display, bounce to main, resize to their home on 2nd. but that gave me the biggest boost in performance was making the clients set to the right monitor.
