If there's a new UI/HUD system coming where we can add the trackmap (and other info) relatively easily on screen, all the better. As mentioned, there's no timeline provided, but there are a few alternatives in the meantime.
Just wanted to poll the general interest, and wondering what everyone's preferred option is...
The first is to display the map on the screen. I did a quick experiment (see a few posts above) where the trackmap is overlayed on top of the game. The downside is that you have to run rFactor in borderless/windowed mode. I can improve my proof of concept a bit and release it for others to try it.
The second is using an external device. I already made RacePad for iOS devices, which contains a trackmap. I can also make an application to have the trackmap appear on a separate machine (running either Windows / macOS / linux). It wouldn't be a huge effort, so if people have a laptop or second PC/screen on hand, that's an option as well.
Android on the other hand is trickier. I don't really have the time/will to invest in it, but I can always check if a very basic app is feasible.
