Game Mechanics: Run speed

[Tovin]

I just started on the server but I have experienced a similar problem with run-speed. Periodically (every 20 seconds or so), my character will slow down drastically (to walk speed) for about 3 or so seconds. This happens outdoors on flat surfaces as well as in dungeons. If I am running away during this time, mobs easily catch up to me and thwack me from behind. Even with SoW I get slaughtered by the mobs. On the flip side, when the slowdown is not occurring, I can strafe without SoW sufficiently fast enough to avoid getting hit.

I don't know if this is a system problem (I run Windows 7 Dual Core). Outside of this problem, I haven't experienced any other technical issues with the game.
