I wanted to see, if there would be a list of tools using the UDP Telemetry, but there seems to be none.
So let's start the thread. Other developers, please add your tools, so we can share what we have done.
I go first: I have been developing my Telemetry tools since the first PC version of the F1 game, so yeah, I have seen a lot of stuff.
In short, with my tool you can:
Save your telemetry data and compare the laps. You can do real-time comparison agains fastest, session fastest or reference lap
Real-time track map with the pit window visible (where you will land after good pitstop),
Track map can show optimal line, fastest lap line, lines driver for seeing trends on your lines
Extensive fuel/race info for getting most out of the racing (e.g. how to end the race with 0.01kg of fuel left)
Visual comparison of laps in lap comparison tool
Race history, track position history and laptimes graphs
Save opponent laps in offline and online races and compare them to your own laps (good way to get better faster).
XY Plotters for interesting graphs from the data
Game can be on any platform (PC, PS, XBox). Telemetry tool runs on Windows, Linux and Mac, so you can now e.g. put your spare Mac laptop into a good use.
