Hi. I have brand new pc, I instaled win7, all games works perfect, but l2 is not working correctly. When i play l2 my cpu usage are about ~60-80 and l2 stars laging but when i press on task manager the cpu usage decreases quickly. What I shuld to do that l2 wont take so much "Memory (Private Working Set)" which is about 700 and cpu usage. CPU usage and memory private working set are in "Task manager" or CTRL+ALT+DELT.

Its normal. When u select another window (when L2's window is innactive) L2 goes to 1 FPS, so it doesnt eat ur whole cpu and ram

Nah, its not :>
He said his cpu gets back to normal usage after he minimalises l2 and acitvate manager window.
There is some problem with L2 or... did you install all drivers?

You are correct. Yes I instaled all drivers and if i wount it I think cod black ops would not work. Once when I was in forrtres battle some error come that writes that my some video drivers are stoped and l2 suddenly lagged and view was white I restarted computer and it was ok. But as I said in makes my nervous when I play l2 and it start lagging with cpu usage...
