So I need to know if the used display device is onboard or PCI-E

And I don't see what that has to do with performance decision making?

It's probably a coarse test to determine if mainmemory is used as
videomemory, with all bandwidth problems associated.

This is not 100% perfect, since some embedded VGA controllers have a small
amount (typically 64MB) real videomem.

I had a problem like this ones, but I only had to discriminate certain intel
chipsets (so not e.g. Geforce/nforce 6100), and a simple check for OpenGL
1.5 is enough to guard against afaik all DirectX 9 intel chipsets.
