RE: [PyMOL] Pymol slow on a mac G4 with os 10.1

[DeLano, W. <wa...@su...>]

Yes, the Fink and GNU/Darwin versions of PyMOL are unaccelerated.  As =
far as I know, the only way to get access to hardware is to call Apple's =
platform-specific OpenGL libraries from within a platform-specific =
window. =20

I am still working on the native OSX port, but with competition from all =
the other PyMOL priorities: such as new features, bug-fixes, and =
support, not to mention my own career and personal life, it is taking =
far longer to complete than I anticipated. =20

There was an incomplete test version available with acceleration, but OS =
10.2 has reportedly broken it.

If you can put up with software rendering, then X-windows based Fink or =
GNU/Darwin versions are fine.  But if you want fast PyMOL, then an =
x86-based PC with Windows or Linux is the only alternative (we're =
talking about a 10-50X performance difference of hardware over software =
-- huge!).  Plus, PC's can do stereo -- Macs can't.

If you need fast 3D graphics on a Mac, I'd encourage you to look around =
for other 3D viewers for at least the next couple months.  VMD =
reportedly has a native version...though I haven't tried it myself.
