Error: Zwift requires OpenGL 3.1 or higher to run

I had the same problem today and found two fixes:
1.If i changed to “Fullscreen from 1 to 0” in prefs.xml it worked.
2. But the real fix was setting the hz refreshrate on the connected monitor.
right-click your desktop and choose “display-settings”, Scroll down and choose advanced screen settings and then change the hz.
Mine was set to 30hz and then i got the error with Open GL 3.1, after changing to 60hz it worked like it should in fullscreen again.
I hope this helps someone :slight_smile:
Ride on everyone :slight_smile:
