More and more stuttering

@RudimentaryCheezit Thank you! I will examine this according to your advice. Thank you! Tom

as you may have expected, you might have too many files on JNO (planets, crafts, systems, programs, etc)

try moving some mostly-unused files into another folder outside of JNO, that way you can still get them back when you need to

another issue would be that your screen resolution (in graphics settings) is too high, and should be reduced

you might also have too many active programs running in the background
