Thank you for this article - I have been struggling to fly with X-Plane11 on my 2.6GHz Core i7, 16GB, Late 2012 Mac Mini.
When I ran the 1280x720 benchmark 1 with:
open -a X-Plane.app --args --fps_test=1 --load_smo=Output/replays/test_flight_c4.fdr --pref:_is_ful_ALL=1 --pref:_x_res_full_ALL=1280 --pref:_y_res_full_ALL=720 --pref:_bpp_full_ALL=32
My result of:
FRAMERATE TEST: time=93.5, frames=2162, fps=23.12
GPU LOAD: time=93.5, wait=5.7, load=6.1%
helped me to realize I needed to set it for 1280x720 windowed, and not stretch my window height so much. I am now able to run at 20-23fps with a sim ratio of 1.0.
Thank You - I CAN FLY!
