After my nVidea card burned out I had to rely on the onboard graphics, which apparently had OGL 1.3 - Hex kept giving me that OGL 1.4 not supported message. Never crashed though, excepting when using symmetry, although it lagged heavily when the poly count got too high. Problem solved when I managed to get hold of a newer card.
There was a long discussion on another thread about this and I contacted the manufacturer of my motherboard - turns out that OGL is hard-wired into the graphics and there is nothing to be done to upgrade it - it is apparently not in the driver .
Maybe the experts can give other advice - I could never find out just which OGL Hex does enjoy.
