Yes I use this it works well apart from lap sector times and the circuit map. I’ve not tried to fix these issues it may be a config change or just not compatible with R3E. I will have a deeper look at some point.
I use it, works great. Some of the widgets are designed to use sim specific raw data and need to be adapted to r3e. I even got it to work with some overlays without much fps drop.
I've set sim hub to launch at start-up, and I launch r3e from sim hub now. Overlays work only if you run r3e in windowed mode.
