Effective very soon (if not immediately) GPUGrid will be discontinuing Cuda 2.2 in favor of Cuda 3.1. Most already have this but I wanted to point it out just in case.
Cuda 3.1 should also help boost performance on Fermi cards, so those of you who have them, give us an update if you see some improvement.For the cuda 3.1 based apps the minimum driver requirements are,
257.21 for Windows
256.40 for Linux
Note that some more recent GPU's require a more recent driver just to work.
For example, the GTX590 requires at least 267.91 (Win) and the first WHQL is 270.61.
