It looks like there is some sort of difference in how Intel and Nvidia cards process bump maps (at least in Linux - I haven't verified in other operating systems yet).

The different is most obvious on the baseball stitching and the tennis ball seams - on Nvidia the stitching looks raised, but on Intel it looks recessed.

Nvidia:
bumpmap-nvidia

Intel:
bumpmap-intel

I guess these intel drivers for linux are buggy? Intel on MacOS seems to work as expected.

Same here on Fedora 20 with Intel drivers. Bump map is inverted... Any solution to detect card ?

Nope, but considering that Intel drivers are open source, they probably have some page to report the issue?

I tried to find this page several hours ago. I will find it... ;)
