Do you have a time frame from when this began S1mon?
Yesterday it was playable in the evening. It was like in good old days. Today I logged, I saw the lags and I went out.
As a comparison. There's a russian server, with over 600 players online by evenings, and there's few lag.
Maybe Argonath has lots of scripts, maybe something else. I hope that lags will be fixed soon. I really hope.
