Yes, llvmpipe should provide much better performance than the MS
software driver. But llvmpipe in a Windows guest isn't a configuration
that anyone really tests (including VMware), AFAIK.
Sounds like solidworks is testing the OpenGL driver in some way during
installation after all. The only hope of diagnosing that would probably
be with 'apitrace' (on github). But it might be tricky to do.
As for the rendering artifacts, it would require some general debugging
effort to narrow it down.
I'm afraid I can't help much more than that. I don't have any spare
time and the higher-ups would probably frown on me spending time on a
competing platform.
