What if i just have the standard Rotary stick and not optical, and whats the difference bewteen the 2.
One uses a mechanical switch, the other uses optics (like a spinner). You still need an interface such as Druins (& a keyboard encoder) to interface a mechanical rotary. Mechanical rotaries have clicks you can feel when rotating, optical ones don't.
Also how does the 49-way stick feel when using is as a standard 8 way stick?
OK, a bit sloppy perhaps. I found it works great for stuff like shooters, not so well for things where accuracy is important such as fighters - still playable tho.
