Hello,
about motion sensations, have a look at the parameter Options / Realism / Special effects
/ Visualize momentum effects :
especially when in Virtual Cockpit, you'll see a movement just as your head moves when you accelerate or decelerate.
If you're a speed jet pilot, you may visualize also the G-effects (red ou black view).
Enabling Options / Weather / Simulation Settings / Enable turbulence and thermal effects on vehicle
IMHO, as a liner pilot more than VFR user on light planes, these parameters seems to be sufficient and more valuable than "screen shakers" for "realism".
Anyway, your prefs are the best for you, have good flights...
