System requirements for NL2000 version 5

It is quite simple. If your PC has the required values for Prepar3Dv4, you can use the NL2000 scenery version 5. See: https://www.prepar3d.com/system-requirements/

The 1 m version 5 requires a disk space of about 80 GB and the 50 cm version 5 need a free disk space of about 200 Gb.

The settings in P3Dv4 are very important. Sometimes you have to try things out for the best framerate result. The resolution of your monitor has to be on a minimum of 1024 x 768 pixels.
Of course, will a fast graphics device and more RAM memory give you a better result.
