I've been using Aerofly RC 7 and 8 with a 60 fps when my Mac was connected to a 1080P display. However, since I bought a 4k display, the performance has been (logically) much worse (even with a 50% pixel density), due to the need to render 4 times the amount of pixels. I would like to have the 1080P option in-game, or a 25% pixel density option, to have the same performance again. Would this be possible to add in the next update? I think this would be much appreciated by users with a 4k display that lack the graphical power to render the game in 60 fps.
