Game stops and "catches up"

[Kalandros]

Got a bit of a weird technical problem that I can't identify the source of.

At some point during gameplay, everything stops moving, stops acting, etc - I can still cast spells, can still move around.

Chat works fine, I still see anything someone said at the time they said it.

And then after a few seconds, the game "catches up" to everything that occured since the "freeze" (the graphics never stop, the 'idle' animations are still going, just no movement from monsters and other players, only I can act).

So basically, I'm fighting T8 - freeze occurs, ballistic missile is cast during the freeze, after the freeze I see everything happen in a "fast forward" fashion and I'm dead or alive depending on how others reacted to my non-reaction.

This happens anywhere in the game, at random intervals.

I really wonder whats going on and how I can fix this.

The chat works fine during the freeze, so its very odd.

Is this CPU related? As in my processor stops handling everything and then everything goes through at once to catch up?
Is this GPU related? Task Manager and other windows things to analyze CPU usage show no drop in CPU performance or sudden 'maxed out' status, so is it my graphics card?
Is this internet related? I never get logged out during those "episodes", but im not sure if I have a disconnect icon next to my name, ill have to ask if it happens when I can communicate with someone.



Whats going on~~
