SurferEQ 2 requires OpenGL 2.1 or better.
In case OpenGL fails to respond properly SurferEQ will open with the OpenGL area showing only black.
It will still process audio as expected but the graphical UI won't be available.
- Check if there's a newer version of your Graphic Card (GPU) Drivers.
- Upgrade to a newer graphic card.
(We've seen such issues mostly with old Intel Graphic Media Accelerators lacking full OpenGL 2.1 support)
* This is relevant only for Windows.
