I'm getting insane lag at times, which I'm confident is a game optimisation and server performance issue.

My rig:

Motherboard: Gigabyte GA-Z170-HD3P
CPU: Intel Core i5-6500 (Skylake)
RAM: 16GB HyperX Fury Black Series (2133 MHz DDR4 CL14)
GPU: MSI AMD R9 380 (4 GB GDDR5)
PSU: Corsair CXM Builder Series Modular (600W)
SSD 1: Samsung 250GB 850 EVO
SSD 2: Samsung 500GB
OS: Windows 10 Pro (64-bit)

In group runs, whenever there are a lot of particle effects (RK and LM skills), there is very bad lag, even if I'm down to Very Low settings. In fact, on many occasions there appears to be no noticeable difference in lag on Very Low or Very High.

I also get some bad lag periodically in landscape, especially Minas Tirith and Pelennor. Yesterday it was insanely bad, no matter where I was, with long load times, chat disconnects, client freezing (never happened before), long delays on skills and quests opening/completing, etc. No problems with my net or PC for anything else.

I have ~90ms latency (Ireland here), with 0.0% loss. 240Mb broadband.
