I just realized that 3rd and 4th cores are working at %100 constant. 1st and 2nd core are working around %25-%50. Is it okay?
No, certainly you should not have 2 cores that are maxed out, and 2 cores that are doing basically nothing. Make sure your CPU Strategy is "All windows use all CPU cores".

Other than that, no I don't believe there is much you're going to find to do to improve your ping by changing settings. (And frankly, 100ms is not all that bad, certainly would not cause a 2+ second delay)


The issue you're running into is not client side.

I think what you're looking at is the same thing a lot of players have been complaining about since 8.1: https://us.forums.blizzard.com/en/wo...-latency/50358
