Truthfully, played much of the last four days, had a couple of spikes and that was all, very smooth actually.
FYI-- PC, NA, and PvE, normal questing, Dolmans, instances and Public Dungeons.
Update: Still some skill delay for sure, but no bar swap delay, and my friend says that my skipping everywhere. But I would venture to say its semi playable. Still definitely needs to be fixed, but something is happening
Seriously bad this morning on Xbox CDT NA. I tried again this evening and there was some lag but it was playable for and hour or so and then I got kicked back to the home screen so I quit. It's not always awful but it is often enough to make me do something else. I'm just questing in Morrowind and there weren't even that many people around.
Ps4 na was fine for me until a guild trader I'm in started a recruiting challenge. Every time a new person joined the guild I got a second delay. Unfortunately it seemed pretty successful so I had some fun in a dungeon I was in.
