Stop a thread flooding the CPU without 'sleep'

I have a thread that sends x/y coordinates to some output. Without a Sleep(1) in there it hammers the CPU (mine at 13%) - but the output is extremely smooth. With a Sleep(1) in there the CPU usage drops to 1% but a slight stutter is perceived. I feel like I need a Sleep(0.5) or something. Something to just pull back the thread slightly from going at 100%. But sub Milliseconds sleeps do not seem possible.

Your Thread.Sleep while have a maximum precision of about > 10 ms. So, if you want do have higher precision, you will need dedicated hardware. This can be a CPU, a GPU or even an audio clock.

If you use the CPU you'll see the high workload just to get the timing right. Depending on your needs you can pick one.
