Pretty much ever since TWW came out I’ve been dealing with huge lag spikes (10-20 seconds) when anything big is happening on screen. As you can imagine instanced content is sometimes unplayable. I notice latency (world and home) is also high for brief moments also.
I’ve switched ISP’s and it was happening on both. Have gigabit fiber now so you’d think it would be an improvement but no. Is this something others have experienced or is this on my end somehow?
PS: no crazy addons either, same stuff pretty much everyone uses.
Let’s check the options menu, check the Network options, and turn off/on Optimize Network for speed, and if IPv6 is off.
Also to check, a full UI reset, including CVAR clear is recommended now, no crazy addons or not.
More speed in the game does not equate to better route, if you are still experiencing High latency all ISP’s in your area might be using the same routing peer to get traffic to Blizzard.
We may need more specific information about your PC if nothing else, what hardware, os, maybe a dxdiag if windows, but let’s start with the basics I guess. Having both FPS drop and the client showing high latency may be related, may be a hardware conflict, hard to tell with little information.
