    hey guys, i came across this thread awhile ago but registration was closed so I was not able to reply.

    For optimal performance on nVIDIA CUDA enabled cards please specify the block switch to No. of Shaders /8 and threads to 512

    So here is an example:

    GTX460 (336): Blocks=42
    GTX470 (44: Blocks=56
    GTX480 (480): Blocks=60

    GTX560 (336): Blocks=42
    GTX570 (480): Blocks=56
    GTX580 (512): Blocks=64

    This should allow you to reach maximum performance and shave off some time to the default values.
    Give it a shot and post back.
