Nvidia's multi-gpu anti-aliasing/low gpu usage

I have a GTX 690, and very low gpu usage while playing games. Only one thing solves it: multi-gpu anti-aliasing, via nvidia control panel.

GPU usage goes from 58% to 90-98% on both gpu's, and the fps boost is big. From 50-70 to 70-120.

My problem is that this works ONLY for single monitor. When I enable nvidia's surround and 5076x1080 resolution the multi-gpu AA isn't available anymore. GPU usage is back to 50% and fps is 37-60. It doesn't matter how much graphical settings I turn up, or apply more anti-aliasing.

Anyone knows WHY I can't choose multi-gpu AA with nvidia surround?

Anyone knows how to improve gpu usage and fps in another way?

Hey there, I've being having some issues with low GPU utilization on GTX 690 as well with a single 1080p monitor, I'll give this a try and see what happens.

I'm not looking to add anymore monitors soon, but if I do I'll try and see what happens, in the mean time I hope someone with expertise will address your issue

hey there, I tried it and it still didn't fix the issue for Crysis 2, if you don't mind sharing what's the exact settings that you have?
