Orbit Rendering Performance Issue

[adsioho]

Description: When I select the orbital frame or Lagrangian point frame in the reference frame selector,
the game immediately becomes extremely laggy with only around 1-10 FPS,
making it nearly impossible to create maneuver nodes properly.
How is rendering a few lines putting so much stress on the graphics card? ?

We are aware of this issue and have been working on it for about 3 months. #4213, which will be in the next release, Lagrange, should improve things. Note that the load is on the CPU to compute the lines, not on the GPU to display them: on my machine the GPU utilization is around 10% but 5 cores are in full use for the computations.

This being said, I have to point out that your report is entirely unhelpful:

1. You are not telling us what solar system you are using, and for what celestial(s) the UI is laggy.
2. There is a difference between 1 and 10 FPS; tools are available to make proper measurements, please use them.
3. You are not telling us anything about your computer: Principia wants many cores; if you are running on an old machine with a limited number of cores, or on a laptop, you won't get great performance.
