CPU is not utilized, but low FPS

the sim is halving that because of the ultra wide being sort of seen as two monitors.
Turn off the nVidia frame cap, turn on the in game V-Sync and set it to 1/2 for 60FPS or (more likely to work) 1/3 for 40FPS.

Interesting statement. I will test your suggestions next time.
