Hi,
I've been running DIALux on fusion 11 with no problem. As far as I can remember it uses OenGL 3.2.
I've tried updating to the latest Dialux version and get an error message that 'Your graphics card does not meet the system requirements. You need at least a OpenGL 3.2 graphics card.'
As far as I can see, OpenGL 3.3 is activated and I have no problem uninstalling and reinstalling Dialux 8.
Any ideas?
