With the maximum resolution textures (16384x16384 pixels for a world tile and 8192x8192 pixels for a cloud and a normalmap tile), expect a minute or more for the loading, around 6GB of GPU memory and 16GB of RAM to be filled. If you can afford it, there will be no other loading bottleneck afterwards. These numbers can accordingly be lowered using lower resolution tiles. | With the maximum resolution textures (16384x16384 pixels for a world tile and 8192x8192 pixels for a cloud and a normalmap tile), expect a minute or more for the loading, around 6GB of GPU memory and 16GB of RAM to be filled.

Finally, while it is possible to use Earthview in rendering schemes other then ALS, this is neither supported nor endorsed. While they work perfectly well for the normal operations envelope of a flightsim, at high altitude the default renderer as well as [[Project Rembrandt]] do not render a realistic horizon line, plausible atmosphere visuals or the hard shadows of outer space and Earthview can not compensate for these issues. As such, when using the [[Compositor]] as the rendering pipeline, it is compulsory to default it to ALS | Finally, while it is possible to use Earthview in rendering schemes other then ALS, this is neither supported nor endorsed.

As such, on old flightgear versions (up to 2018) when using the [[Compositor]] as the rendering pipeline, it is compulsory to default it to ALS with --compositor=Compositor/als. Flightgear versions 2020 to 2024 uses the Compositor by default and ALS rendering can be switched on in the Rendering menu. | ||

To get full advantage of Earthview, and your graphic card, you may install and use your own high resolution tiles as well as normal maps having a alpha channel to trigger parallax mapping. | To get full advantage of Earthview, and your graphic card, you may install and use your own high resolution tiles as well as normal maps having a alpha channel to trigger parallax mapping. | ||
