That makes little sense. CPU would not affect input time. With CPU issues you might see a drop in framerate and general performance, but there's no way ones CPU would affect the time it takes between a button press resulting in the character making an action, especially if everything else appears to be running smoothly. This looks like a connection issue, which have been rampant lately. I've been encountering high ping and occasional lag-spikes up to 10+ seconds too, as an EU based player on NA servers. In fact, if I log in right now, my ping will be in the 800-1500 area, because that's what it usually does around this time of day (EU morning), for whatever reason. I can play fine during the night, but during the EU day, when US servers should be under comparatively little load, I get massive ping and lag spikes. I suspect this may be in part due to the current pandemic and the higher amount of people working from home, over the internet. /edit: There's a thread about connectivity/latency issues here: https://en-forum.guildwars2.com/discussion/111982/an-update-on-game-performance-issues#latestMost likely connected to that. I was having similiar issues, not as bad. upgraded my CPU and problem was solved. Doesnt really hurt to check on and monitor how your CPU is doing :)I was using really bad mobile internet connection (used my phone as mobile base station) and never had any problems even slightly close to that. If that is connection issues then you must have really really bad connection and probably play overseas server.
