Object framerate


My first posting. :)
Not sure if this is the right forum. Please advise me if this is the wrong forum and where to post my question.

I like to display 3 objects on the screen that flickers at different frequencies.
Object 1 displays normally like what you usually see on a screen.
Object 2 displays with flickering frequency. Maybe it flickers at 20 Hz.
Object 3 displays with another flickering frequency, maybe 13Hz.

Can this be done in software (using CUDA)? Is this something limited by nVidia hardware? How does nVidia hardware card deal with display of objects at different frequencies?
Note. All 3 objects display at the same time on the screen.

Thanks a lot!
