I recently installed the latest ForceWare drivers from NVIDIA, 91.31. Works great, the new control panel is also quite a nice addition.

However, my machine is a single GPU machine and every time on a fresh boot I am greeted by a popup balloon from the tasktray stating that: “[...] SLI multi-GPU rendering has been disabled.”

Of course having only one GPU that makes, but it is kind of annoying.

I encountered the following article over at NVIDIA’s customer help. The fix, for now, is to incorporate a registry change. In a newer driver this will apparently be fixed (apparently it is in the beta driver). The registry change, however, disables all balloon notifications, which is a bit drastic in my opinion.
