Why go for a HDD and not an ssd?
Why did you select the 10700F (thats the one without graphics if i'm correct)
What video card did you select or is that the GTX 1660?
Did you check your temperatures?
Do the fans turn on. Might be an gradual overheating thing.
Get GPU-Z It monitors video car AND CPU temp. (under sensor tab.
Start it up befor MSFS so you get an historical view.
Installed it on PC and android tablet, was a breeze and works fine.
Wished you could decluter it some but I understand that is the nature of the used maps.
Good app, a lot better then the VFR map in MSFS.
Maybe I'm not getting it right but do you mean by SW and Microsoft SIdewinder 2?
If this is the case I have that one and it does not work in MSFS 2020, or I should say I had the same problem as you describe.
I replaced it for a Thrustmaster 16000 and that works great (for me)
Might not be top quality but price/performance is fine!
