There’s a couple of issues with FSR and SU10 Beta.
Overspeed causes the mouse zoom to go crazy (it won’t reset to default zoom option setting if you change zoom level), and Turbulence causes camera to go crazy (hi speed shaking).
Turn them both off. It doesn’t seem to happen with all planes (I’ve had it happen with a handful now), or all the time, but when it’s triggered it’s a mess. I still don’t understand the trigger condition(s), but have nailed the issues down to those two settings.
I sincerely wish the dev would also turn off Cabin Ambience, Crash Screaming, and Scary Ride (and maybe Coughing too) as default settings, as it is becoming a really annoying experience having to turn them off every time I try a new plane/livery combo. Seriously, seriously annoying that these are on by default, they are experience options that should be opt in, not opt out.
Having to do this every time (and it can be a regular occurrence due to plane/livery combos) really generates a bad feeling towards the app, despite its good points. UX is not just the main use, it’s how you use an app.
