I really think that the way the unreal engine has handled input since UE3 has felt really sloppy.
I would love to feel like I had 1:1 input into the engine from the mouse.
No matter what combination of Sensitivity, Scale and Exponent I use I cannot get the mouse to feel sharp responsive.
Also this is hindered by the frame limit on none “smooth frame rate” settings.
I really hope you can find it in your heart to give me this one feature! lol
