Hi,

Please keep wine-devel in CC. There are more developers than just
myself :-) .

There are OpenGL flags winemac.drv can set to disable the software
fallback:
https://developer.apple.com/library/mac/qa/qa1502/_index.html . What
happens when you set them? Do they influence the reported capabilities?

The Mac driver is already setting those, by default.  Software rendering is disabled unless you set a registry setting.

That doesn't mean that fragment processing and vertex processing are done on the GPU, though.  Disabling the software renderer is not the same as insisting that nothing significant gets done in software.  So, evidently, it doesn't affect how many uniforms are reported.
