I cannot run at all on Vista 32-bit, ATI X1400 (on a Dell laptop), driver version "8.360.0.0 - ATI Mobility Radeon X1400" as reported by GPU Caps Viewer.
Hyperion3D 1.16.0, when launched, draws its window but nothing in the OpenGL area, and immediately says "Not Responding" and never does anything.
I saw this about 6mths ago with an earlier version of Hyperion3D on this same laptop, exact same behaviour, I could not get it to run. And that was also with Windows Vista, but a previous install (I just reinstalled from scratch a few weeks ago). A colleague's laptop (almost identical but with a Core 2 duo instead of my original Core duo), same video card (X1400), but running XP SP2, worked fine.
Any idea what is going on?
