WotLK wotlk warmane game client freezing

[digib]

Hello!

Fresh download/install of warmane's wotlk 3.3.5 game client, zero addons, tried the LAA memory fix, updated video drivers.

Every couple minutes the game client will completely freezes, wait a few seconds (5-10) and it returns to normal.

Connecting from North America, average MS = ~160, zero packet loss (extended ping tested).

Also moved the game client folder from an SSD to a physical HD.

Anything else I might try to fix this? I really like this server but it's unplayable until I get this fixed.

Thank you in advance.
