Jedi Academy is an OpenGL application as far as I know, so wined3d doesn't have
a lot of influence on performance there. The log seems to confirm that, all the
D3D calls in there are just for getting hardware information like e.g. the
amount of available video memory, it doesn't do any rendering using D3D. I'd
say this one at least is purely a driver issue.

Marek Olšák fixed some similar issues as my patches attached to those bugs did
in commits 87f94e6f80dcdc3933edee24b1f7a6e355c4abaa and
a0510fa7737eaaaafffd9748f603cf0231e8321a. (These should be in 9.1, but since my
patches didn't help for you, these probably didn't either.) He also made the
fallback quite a bit faster in commit ea63491629f48099371f725e7c3779f2982d7a52,
but that's for Gallium3D based drivers only. Perhaps the attached (Mesa)
debugging patch can give some more information about what formats are actually
involved, but I really think the Mesa bugzilla is more appropriate for
discussing this.

Disabling GLSL in general makes things worse for anything that isn't the
proprietary NVIDIA driver, or cases where only reporting shader model 1 would
improve performance. (And in the latter case there are other registry settings
that are more appropriate.) But yeah, probably not the issue here.
