Unresponsive User Input

[domjanabi]

User input is unresponsive because of the low framerate (for me around 10 fps). I doubt it is because of the image processing.

• [x] Find a way to increase the framerate

For the most part input is the bottleneck, except for algorithms that use kernels, especially those that use kernels larger than 3x3. So far BoxBlur is the only algorithm that can consistenly be slower than the input by using a larger kernel size.

input usually (with exception of boxblur) 16 to 60 times slower than rendering.
