This idea dates back to early 2016 when a few FlightGear contributors were discussing a reddit review of FlightGear which highlighted that FlightGear's default graphics settings didn't seem to fit/match the graphics hardware available. | |||
FlightGear core deveoper Erik Hofman came up with the idea to preselect more appropriate default settings based on parsing various GL_* strings (in particular GL_VENDOR), i.e. detect the video card and based on the GL renderer name turn on [[ALS]] (or not), turn on water shader (or not), turn on the 3d city shader (or not), etc. | |||
The defaults would not be touched but based on the detected video card certain options would get enabled, making the first impression much more pleasant (for first time users). <ref>{{cite web | |||

Furthermore, suggesting that it could be a good idea to make sure the configuration has at least 20fps at KSFO. | |||
Also it would be a one time configuration for after a (re)install. The settings would be written to a local configuration afterwards so users could still tweak for their own liking.<ref>{{cite web | |||

Other contributors, like Thorsten mentioned, that it does not seem to be a technical problem - to query a string from the property tree is easy, to write a routine which sets other properties based on what the string says is equally easy. | |||
The problem is the meat of it - someone has to know what settings are likely to run on what graphics cards. And someone has to write the routine that does it. Then it's done. <ref>{{cite web | |||

We can do that by settings /sim/rendering/* as required, i.e. loading pre-configured profiles from $FG_ROOT | |||
CPU/RAM and VRAM info is not currently available, but we have patches providing this sort of info <ref>{{cite web | |||

For example, $FG_ROOT/gui/dialogs/about.xml and rendering.xml are already accessing some of the GL* data via properties, e.g. to display the Intel warning, but also the GPU vendor info: | |||

Thus, we would ideally introduce 3-4 "vendor"-specific folders and then introduce a PropertyList XML file where the RENDERER string is used to select a certain default configuration. | Thus, we would ideally introduce 3-4 "vendor"-specific folders and then introduce a PropertyList XML file where the RENDERER string is used to select a certain default configuration. | ||
For testing purposes, we could promote this features on the forum/website/IRC and facebook to get people involved with testing, and to provide feedback - so that we know what settings work well enough, using Nasal's http APIs, such feedback could even be gathered online. | For testing purposes, we could promote this features on the forum/website/IRC and facebook to get people involved with testing, and to provide feedback - so that we know what settings work well enough, using Nasal's http APIs, such feedback could even be gathered online. | ||
