So, I installed REXWF in light of current MSFS weather issues (MSL v AGL cloud bases/haze/incorrect wx) and it is really good although not perfect. I noticed that when the weather synthesis is taking place (in my case I set 30 minutes between updates) while flying, the sim grinds down to single digit FPS for several seconds before recovering to smooth flow/fps. Are there any REX or MSFS work arounds to this issue besides not using REXWF?
