It is great that Aerofly FS2 runs so well on our lower end computers, even in VR, though dense scenery like flying over Amsterdam or Paris exceeds the amount of VRAM on our cards. But I enjoy those other places, so much to choose from..
I can recommend Innsbruck and South Florida, both have an animation add on for free now too. Innsbruck is probably still on sale from Orbx directly...Great scenery with a smooth frame rate in VR for me in medium settings.
I will spend 250 in the future for a better graphics card (and more system RAM) but will probably go for VKB rudder pedals first to enjoy the R22 even more....
Have fun!
