Support for older hardware

[Esgeriath]

When I first lunched remouse I experienced massive but variable lag. Delay was fluctuating between barely noticeable and up to 2 seconds. I figured out that this was probably due to my old processor not being able to process input stream. I managed to get no lag with the cost of performance - I stopped processing 4 out of 5 mouse movements. Here's my code:

Perhaps this could be added as a feature, with appropriate flag.
