You're leaving out quite a bit of details about your set up. Are you using Inner Space with config.wtf virtualization? Are the
correct monitors set within World of Warcraft's game options to each game instance or through Inner Space's game
configuration? Are you using cross-monitor swapping?

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.
