I can do this upon zoning. I tried PoK, Bazaar and Guild Lobby. I would zone in, run a few feet, then the game would freeze for about 2 seconds and then come back to normal. Never happened before.
My system is good enough to run this at 64bit. The freeze happens just after zoning or logging in. The whole game just locks up for a couple of seconds. Running a Samsung m.2 nvme drive, so doubt that's the issue.
My first questions: Is this a new problem? If so, when did it start? How full is your M.2? How much RAM do you have? What kind of video card/chip do you have? How large is your log file?
That was happening to me on a couple characters before the patch. Move a few feet after login and then it would freeze for a few secs, then come back.
Happened to me on 2 toons (out of 4) while in my guild hall. Very weird. Also, all of my toons were in the guild hall, I camped, came back later and at the screen showed them as in the guildhall. Logged in and 1 of them (even though it said on the screen they were in the guildhall) came up in oceangreen hills. Very weird.
