Introduction

The goal of this article is to document which settings in the NVIDIA Control Panel seem to work best for osm2city with Atmosperic Light Scattering (ALS) on Windows.

The configuration has been tested on:

  • Windows 10 Home 64bit
  • NVIDIA GeForce GTX 1060 6GB
  • Driver version 385.69 (note that it is highly recommended to use NVIDIA drivers and to use recent versions)
  • FlightGear 2017.3.1

The configuration and configuration choices might differ for different NVIDIA cards etc.

Accessing the NVIDIA Control Panel

The settings discussed in this article relate to Tab "Program Settings" in "Manage 3D Settings" in the NVIDIA Control Panel. The NVIDIA control Panel can be started by right-clicking on the Windows Desktop.

It requires to select or add a program to customize. You have to point to "bin\fgfs.exe".
