the monitor taking additional time to process the image before presentationДelays caused by drivers and OS: Windows, Linux and Mac all perform further processing on the images, depending on settings and this can delay your visual stimulus delivery by a further frame interval or more

The following issues are extremely common and until you actually test your experiment you donвЂ™t realise that your timing is being affected by them:ДЄdditional delays caused by monitors: e.g. The sources of error in stimulus/response timing are almost never to do with the poor precision of the clock. Many software and hardware manufacturers will suggest that the key to good timing is using computer clocks with high precision (lots of decimal places) but that is not the answer at all. Very often a computer is not optimally configured to produce good timing, and a poorly coded experiment could also destroy your timing (which is one reason we now recommend even good coders use Builder!). The longer answer is that you should test the timing of your own experimental stimuli on your own hardware. For detailed Studies of timing see Bridges et al., 2020 PsychoPyвЂ™s timing is as good as (or in most cases better than) any package out there. Can PsychoPy В® deliver millisecond precision? В¶
