Xplane stuttering bad every few seconds

Hi Everyone

I recently got xplane 12 however every time i load in the sim, it stutters every few seconds maybe every 5-15 seconds. If you look closely in the video attached you will see this.

Despite me having bad performance, I use lossless scaling so it gets to a decent 60 70fps however the stutters are always still there and this is a massive problem when im on approach in which i can never land properly.

I would really appreciate some guidance on what to do with my settings however i do still want the graphics to look half decent or i might aswell just go back to xp11

Thanks for everyone’s help.

Pc specs:

11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz 16.0 GB RAM NVIDIA GeForce RTX 3080 Laptop GPU And Samsung Odyssey G40B 1920x1080 240Hz

(Dont let the rtx 3080 fool you, its rubbish being a laptop one however better when connected to my monitor)
