That, and Direct3D isn't portable to any other OS. So if CL wants to make a Mac version and a Linux version, OpenGL is the (only) way to go.
I just now had a report of an Intel 810/810E not running Bridge Builder (see here), and it has a severely limited OpenGL line width range (1-3 at 0.5 granularity). Could this be a problem?
Which OpenGL extensions are required to run Pontifex or Bridge Builder?
Chronic Logic: anything used by Pontifex not on this list?

The VIAO has an ATI Rage Mobility M1 chip set.
Currently using driver build M6.11.74-T04, version 5.00.2195.4037 - The default drivers from Microsoft.
I have tried all drivers and tools mentioned by Baggio but alas nothing helped.
Why use OpenGL and not DirectX?
