I’ve had the game uninstalled since October for similar performance woes — only difference in my case was that the latency meter was registering 300-999+. I’ve been seeing more reports since the power outage, though, of massive skill and animation delay as described above with no corresponding spikes registered by the in-game latency meter. Interestingly, according to the last significant dev update in the 100+ page thread on sudden terrible performance dating back to May 2024, ESO’s “ping” meter doesn’t actually reflect ping, and one of their plans is to fix that. I doubt they’ve done any work on it that quickly, but it’s worth noting just in case.
