from the 0.18 patch notes (that's all i found on that issue)
For some people, the game will freeze for 4-6 (actually 4-11 or so) seconds at irregular intervals. During this time nothing updates - the screen locks until it comes back from this issue. If you have your task manager open you will see the CPU go to 100%. We are aware of this issue. We don't have a fix yet, but we're working on getting a fix out for it as soon as possible.
when is this going to be fixed? before 1.3 this occurred every once in a while, now after the new patch i got it like 4-5 times within 5 minutes in cyrodiil.
actually there was one patch where it didn't happen at all ... why is it that bugs are introduced again and again after they've been fixed already?
DAoC/Mythic legacy?
