Significant timing delays in triggered looped task
I am attempting to re-implement a task I was given in E-Prime format into opensesame to allow me to send triggers to my EEG setup. Unfortunately the timing of the image display, even in the untriggered practice loop, is significantly slower than the duration I entered into the GUI. The timing of the first two images seem okay, but the next three are very slow. Some of the delay, but not all, seems to dissappear if I remove the mouse response object, but I need this to be in there.
I am using the latest OpenSesame release (3.2.8) and a 64 bit Windows 10 operating system. I am using the Expyriment back end - I tried switching to legacy after reading forum posts but it didn't help.
Any ideas much appreciated!
