How to minimize ressource with Stellarium

[rguinamard]

Hello,
I have a microsoft surface go (8 Go RAM 128 Go disk) to run stellarium. I use it to locate deep sky objets on a large scope so I have to download very faint stars
I notice the surface is slow when running stellarium.
How tune stellarium settings to minimize the ressources used by the program ?
Regards
Raphaël

• do not use ShowMySky atmosphere, use the old model (Preetham)
• disable Satellite plugin
• Do not install DE4xx ephemeris files
• Use as few minor planets and comets as possible
• Disable other plugins you don't need

Check this screenshot:

Preetham is the default atmosphere, so it's likely the one chosen already.

I think ARM builds omit support for this model, so you may not need to look for it. If the Atmosphere Details dialog doesn't have Visual Model section, then you don't have it.
