To finish with this discussion, if u want to use it, use it (that depends on yourself) its a double-edged weapon, if u have a good regedit (purchased) it can improve ur internet connection (according to what i have understood) but at the same time it reduces the life time of ur processor (PC)
A long time ago there was a discussion when Daviq was using regedit, the truth behind its that he put a lot of regedits that he fucked up his pc as well as his gameplay (he was too laggy, couldn't do anything), he had to format his pc, but at the same time it burned much of his processor.
Honestly, thats why i dont use it anymore since ago long time, im happy with my 100ms

.
If u want more doubts or helps about the regedit ask one friend mine Zeds_58#8308 he does that.
