[PyMOL] Pymol 3 Timeline issues

[Istvan K. <iko...@gm...>]

 Hi,

I have had these issues with the new timeline. It works fine with scenes
and short multi-state objects (like those showcased in the Pymol 3 online
visualization course) but when it comes to real life MD trajectories I
found two "dealbreaker" issues.

1) With complex movies based on MD trajectories and not scenes, the Draw
mode is not working. If I select Draw to generate a movie file quickly for
testing then (a) it takes almost as long as Ray Tracing and (b) the movie
is complete garbage, showing only random parts of the system.

2) The Ray Tracing mode works fine, but processing time is prohibitively
slow because Pymol 3 only uses a single CPU core for ray tracing. Pymol 2.5
automatically uses all the available cores for ray tracing. The way Pymol 3
is right now, it takes 24-48 hours to produce a 3000 frame movie, which is
only 100 seconds.

Has anyone encountered similar issues?

Thanks,

   Istvan
