You can ask the author. I've found this information on a changelog:

But,

Not at the moment.

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.

GTX560 Ti has 384 shaders.
