Personal Benchmarks on a midrange $800 PC (video card bottleneck):
-default: 90-190 fps. 300 max.
comanglia mid pc: 120-300. 700 max.
-default is much, much higher in terms of quality settings (to the point where particles scare me), and it is buttery smooth, same as comanglia. After switching back to Comanglia I get occasional drops to 60fps, however it's barely noticable and I'm sure its fixable.
