I haven't tried it with acc, but it is free to use. That being said it has a little nag every so often, silly quality of life features such as minimize to tray and running at 60fps are locked behind the 6€ registration.
I'll probably end up buying it just because it seems like a quality piece of software.
Thanks for the response I'll check it put. BTW how is sim racing on monitors with different refresh rates? I have a 60hz and 144hz but haven't tried to expand the view. My guess is I would have to reduce the faster monitor.
From what I understand the 144 middle monitor will still run at 144, but the two running at 75hz will "lag" behind producing a slight distortion at the bezels. That being said, I do not notice anything different.
