I just use an aircraft without a front propeller 
Just try this and let me know:
TAA 100 + SS 124
120Hz + Motion Smoothing / Fixed Rate 24fps / Prediction 25ms (or 144Hz with close to 24fps/25ms values)
If your system can’t keep up, lower TAA to 80 (all the other settings as in “My VR Settings - Index” but with Terrain LOD 100% instead of 50%)
This presumes you can render comfortably with some headroom at this rate. Try a not much demanding aircraft to get started (Longitude or C172 Analogue are working fine with me) over Hawaii or a flying in the ridges of the desert south of Dubai to get started.
