Constant Lag and Stutter

Game mode: [Online | pve]
Problem: Performance
Region: EU

EU Official PVE server 3011 has constant lag, stutter, and pop in. Ping times vary wildly but are never good. Lag and stutter is visible when just walking around the map or even my base, and combat is infuriatingly bad with these problems. Every one in my clan has the same problems with this game.
Is there any chance of a performance improvement patch soon?
