The authors have published an updated performance assessment of PsychoPy. They conclude that:

"the most recent versions of PsychoPy can achieve the highest levels of precision and accuracy in the presentation of brief visual stimuli. There is no reason to think that occasional timing errors found in benchmarking tests with many trials per loop can pose any problem for standard experiments developed by researchers. Properly used, PsychoPy is an excellent tool for psychological research even under the most demanding conditions."
