corrected the framerate locking which occurred with some Linux graphics drivers.
added more pre-mapped controller bindings.
The newly added XInput support means that Xbox 360 and Xbox One controllers should work better, and all other XInput compatible controllers will now be automatically detected and pre-mapped. Although they're pre-mapped, you can remap them however you like.
As for other controllers, these non-XInput compatible controllers still use DirectInput. For your convenience, RCR automatically pre-maps 42 different DirectInput controllers, but you can also remap them however you like.
Don't worry if yours isn't listed. It just means you need to map it yourself.
