at this point I can't tell so I blanketed it as lag.
on one hand it is definately framerate drop, but the other hand any thing I do is delayed greatly. IE I pushed a button 3 minutes ago and the slow frames showed that, and only after those three minutes does what I tried to do.
Just today my client crashed 5 times with an "unknown error" - my whole pc slows down to the point where I have to manually force the game client shutdown through task manager, where it is running upwards of 1,500 mb ram.
Yes I have been experiencing noticable lag I will experience lag in places where I never noticed it before, and I am using the same pc and settings as always, and never experienced any type of lag until now, but I am pretty sure it deals with LOR and it's pretty understandable, since Cryptic made some significant changes. I'm sure the lag will hoopefully be resolved soon.
