For several years,I have been putting off adding REX to my FS9 . Was kinda worried that it would beat up my frame rates since my PC isnt exactly a speedster. Then,after being so bored I couldnt see straight,I decided to get REX and give it a risk.
I am COMPLETELY impressed with it. Great scenery and clouds can be had with that program,and if anything,my frame rates seem to be a little better than usual.
You are given the option of using 1200x1200 pix bmps or 520x520 bmps ( now I most likely have those numbers wrong,but not by much). I chose the smaller,and applied them. Really impressed. Thrilled. And satisfied completely !
Well worth the cash.
