Anyone else noticing their card dropping down to 2D clocks. I got home tonight and noticed my PPD on my GTX260 at about 2000ppd??? Opened eVGA precision and the card jumped back to 3D clock speeds but the graph showed that it had dropped down to 2D speeds. This is the second time I noticed this since updating to the 180.48 nvidia drivers. Never noticed this prior to this. Anyone else?
