Thanks for the clear explanation. So de-syncing is still a thing (and it's only related to movement)? Are there any possible solutions rather than a resync button?
Also that explains why it doesn't happen in other emulators which don't have any speedhack prevention mechanism.
Somehow I believe that it might be because of assistant tools like razor, uo steam. Those two tools ruin my UO experience, the game is much smoother when I log on to EA servers with plain client.
I am using RunUO 2.4, since runuo.com is dead, I am planning to transfer everything to ServUO. I am not interested in the new expansions since the server is run at UOR. What are the advantages of using ServUO? Have you ever stress tested a ServUO shard, any performance comparison?
