23 is very low for that setup though. Is it in a heavy plane (A320, 787, DC-6 etc) in a busy place (big airport, photogrammetry city)?
If so, turn down the glass cockpit refresh rate to begin with. That should improve things a bit. After that, the LOD settings (the two sliders) seem to be the heaviest.
Also make sure that you don’t have performance-killing software running in the background.
VMs (including Docker and WSL) can also be eat some CPU. If you don’t know what they are, they’re not an issue – you’d have to install and run them yourself.
I certainly agree on waiting for SU5 which is made to improve this issue (since you’re most likely heavily CPU bottlenecked).
