Bad performance, what did I forget?

[Pocalypse]

Indeed, SLI is made to run a single screen with two video cards, if you wanna use more than one screen you'll have to take off SLI and just run one off each card.

How can I run a screen off each card?

I was under the impression that without SLI, two monitors would run off the same card, effectively ignoring the second card.

I currently have both monitors connected to the top (primary) card. But I have tried connecting the 2nd monitor to the 2nd card and saw no difference.

The problem is the same for the new driver. Aka windowed mode + a few other things makes it fail.

Thanks for that link. Hopefully Nvidia is working on some kind of solution.
