Terrible framerate in map view

[oowoohoo]

I am running an RP-0/RO save with principia, and upon entering orbit where my trajectories are displayed, the framerate drops to nearly unplayable levels. Is there a fix?

Could you share your save with us, e.g., as a gist here on github? It would be really helpful in trying to understand what the problem is.

There is a known problem in map view, where all the time is spent plotting the past trajectory (history). We have been working on fixing it for a few months (see #973) and the fix will likely be in the next version, Чебышёв, to be released on August 21. In the meantime the work-around is to make the history as short as possible (there are controls to do that in the Principia panel).

I made a small save with a rocket taking off and flying for about 12 minutes. In Cayley (the current version) in map view showing the full history reduces the frame rate to 5 fps. After #1493 the frame rate goes up to 30 to 60 fps depending on the viewpoint.

Here is my save.

Fixed by #1506 (as mentioned in the issue, this improves framerate from 8 fps to 55 fps in the tracking station for a pathological example).
The fix will be in Чебышёв, to be released on 2017-08-21.
