Expyriment test suite on OpenSesame
I'd like to know why the visual timing accuracy measured by Expyriment test suite on OpenSesame is bad.
I use OpenSesame with Expyriment on MacOS.
While Expyriment test suite shows good visual timing accuracy, Expyriment on OpenSesame (i.e., I run the test suite in Inline code) doesn't show.
It seems that OpenSesame doesn't use the back-end of Expyriment even though I set the Expyriment back-end.
When I use the Pygame back-end on OpenSesame and run the test suite, the timing gets accurate.
What is the cause of this?
