This is the deluxe version of FPV Freerider. It is focused on bigger and more detailed sceneries.
You need a pretty fast computer for the simulator to run smoothly. If necessary you can try to run it at lower resolution in order to get better framerate (using command line parameters as described in the manual). If you have any doubts whether it will work on your setup, please try the free demo version first.
The demo contains only one scenery, has a limited amount of features and options and a quad with deliberately rather sluggish settings. In the full version you can tune the settings freely to your liking.
