"OpenGL mode is not supported on this machine!"
Hi everyone,
I have some unexpected problems with OpenSesame. Everytime I try to run my experiment I get this message error :
File "dist\libqtopensesame\misc\process.py", line 140, in run
File "dist\libopensesame\experiment.py", line 379, in run
File "dist\libopensesame\experiment.py", line 723, in init_display
File "dist\openexp\canvas.py", line 65, in init_display

File "dist\expyriment\control\_experiment_control.py", line 414, in initialize
File "dist\expyriment\io\_screen.py", line 117, in __init__
RuntimeError: OpenGL mode is not supported on this machine!
Do you know what am I supposed to do ? Sorry I'm not familiar with coding.

Hi,
This message means that the video card/ drivers on your computer do not support OpenGL, which is the library that OpenSesame uses by default to present visual stimuli. You can work around this by using the legacy backend, which doesn't use OpenGL. However, there are some downsides to that in terms of timing (in most cases not crucial though), as described here:

Hi,
As Sebastiaan already mentioned it’s probably either a video card or a driver limitation. On Windows I solved the 'OpenGL error' by installing the correct driver. It might be worth a try to:
