Block breaking particles on "minimal" particles

Unless it is supposed to be unaffected, I don't think there should be the same amount of particles on all three settings. For slow computers, like mine, it makes me break two blocks at once after a two second lag spike.

Whether or not the double block-break has been fixed or not is beyond me, however it seems like nothing has changed with the amount of particles that appear after a block is broken. (1.6.4)
