Unplayable for me

The current version is basically unplayable for me, I have a 1 gigabit connection and a decent rig but on every single server every few seconds I'm getting what appear to be massive spikes where everything freezes then after anywhere between 10 to 20 seconds the server "catches up" with itself - or more correctly all the boss monsters hit land in the space of 2 seconds and I'm dead - again. Guess I'll leave it till the server software gets updated :C

I have the same issues, for long times already.

Here's the workaround: Hit Escape to pause. The shader will load in the meanwhile and you even hear the sound catching up after some seconds. Afterwards unpause, it'll be much better again.
