As most of you know, the F2 "follow" camera doesn't work on newer systems. This won't be a detailed guide, but it tells you the reason and what kind of software you need to fix it:
Apparently, the camera is that slow because Robot Arena 2's framerate isn't limited(except in Wireframe mode?), so all you need is a fps limiter(for Nvidia cads you can use Nvidia Inspector) and to create a profile on there(leave all options unchanged except framerate and set that to 3060 fps, don't forget to add robot arena 2's .exe and to save the profile).
That's all, worked for me.
