Ideally, your program synchronizes drawing of the stimulus with the refresh of the CRT. To do this, you have to use particular techniques for drawing. There is more information about this, and also data on timing of sounds and the button box when properly done, at the Holcombe:ProgrammingInR page. Once you think you've done it properly, you'll need to verify that stim drawing is synchronized with the CRT.

Use the tachometer

It lives in a box on the shelf of the lab

Use an oscilloscope (rarely necessary)
