We should cache our RTS computation to avoid recomputation at every frame.

Expected Behaviour

FPS drops somewhat when InfoText is shown, but decent system remains at interactive framerates

Actual Behaviour

As mentioned in #3265, RTS may be very expensive and bogs down even a 10th-gen Core-i CPU.

Steps to reproduce

Select object (esp. Moon), observe framerate drop when InfoText is visible. Note esp. effect of RTS display.

System

  • Stellarium version: 23.1
  • Operating system: Windows (but likely any)
  • Graphics Card: irrelevant

Logfile

If possible, attach the logfile log.txt from your user data directory. Look into the Guide for its location.
