Hello everybody, I'm running 2 GTX 580s in SLI (or i was) untill i updated from driver 285 to 301.42.
I Went in game and opened my MSI Afterburner and noticed only 1 of my GPUs was being used.
So i looked in the Nvidia control panel and the SLI options were gone.
I'm having exactly the same problem. This happened last time I updated the drivers and I rolled back, but don't want to have to keep on doing this.
Have hunted everywhere online for help with this and it's driving me crazy. Have disabled/enabled the cards, taken them out and reseated them, deleted all previous Nvidia drivers, but still my SLI is not recognised. It's obviously nothing wrong with the SLI setup itself because it was working perfectly before the driver update, so if anybody could provide any advice I'd be hugely grateful.
