I did try and change all the numbers and it still had no effect ,so then by unchecking the solve collision box was I able to relax the frizz explosion. as well I tried a combination of both off and it helped but with both checked that did cause the anomaly. apparently there is conflict between the two.
Also addressing the other subject I mentioned of long load times , every time I load a level to edit it still has to prepare shaders and the opening editor dialog still takes forever to load where in ue4 it’s almost instant.
