Craig Robbins 2b119e1e19 Performance of main client loop up to 2x faster In places, up to 3 times faster 
NOTE 1: This does not mean a 2x increase in framerate. Increase in fps may be up to 1-2fps
NOTE 2: This local 'caching' of settings is not optimal and an alternative solution will be worked on after 0.4.11 is released
