Three monitors, Two GPUs, One screen gaming performance

I've been running triple monitors on a 780TI for years. I only game using one of the screens.

I've purchased a few newer monitors that won't all connect to the 780TI, so I plugged in an even older 660 to run all three monitors (2 on the 780TI, 1 on the 660)

However, now single screen gaming performance (on the 780TI) is dramatically reduced / max framerate dropped 50% with lots of stutters.

Does anyone know of any extra settings/driver changes that can be made to improve performance on the single screen? Or is multiple GPUs w/o SLI non-feasible?
 
try turning off the extra displays while gaming. the system is still trying to driver the extras while you game taking away gpu power. ive seen several other around here with that issue and not only on mixed card setups. other than that maybe ddu and install the newest driver. good luck!
 
The primary is display is connected to the fast card, right? What you describe sounds an awful lot like the system is trying to use the 660 to render games and not the 780.

Turning off the extra displays would probably work, but what I would try first is connecting a single main display to the 780 and other extra ones to the 660. Also, some games have a setting where you can tell them which graphics card you want it to use. Maybe make sure it's not defaulting to the slow card for some reason?
