RAGE with Nvidia Surround problem

[Black Mamba]

I ask you to help
Why does the game RAGE get only 16 FPS and I have Nvidia Surround system with two GTX 580 Lightning.
Signs of Resolution 6040 x 1080 16 fps to me, and when I play with a 1920 x 1080 20 fps to me.
It is too little for these two GTX 580 Lightning graphics. and I installed the update again and all the same, only nepuca more pictures but was again delayed.
I looked on You Tube playing RAGE on the GTX 480 and all of them going smoothly as the surround system.
why can someone help me. Do I need a patch for Nvidia surround.
Sorry for the bad English, I google to translate.

Thank you all for help

Was resolved, it should just install a new Nvidia driver 285.62.
So if someone just does not work RAGE normally let only install Update and new drivers 285.62 and that's it.
In resolution 6040 x 1080, vsinc on, all high, 8x AA = 60 FPS
------------------------------------- 16x AA = 35 FPS

glad you got it working, i never even noticed the issue as i moved to those drivers when they were beta pretty early.

you mentioned 16aa, do you get mouse lag running rage with lots of AA, cause i seem to get quite a bit and its really annoying

from 16AA to feel a bit while you move the mouse, but I play on 8AA and everything works great
