Memory leak?

Hey folks -- is anyone aware of a recent memory leak?

Quick info:

5850, the most recent drivers which fixed AA
Quad-core Phenom ii
Win 7 64
8 gigs RAM
CPU temp 40 while playing

This evening, I was seeing the client chew up about 1k / second with jagged, laggy performance -- but all was well earlier in the day (post-patch).

Question is what were you using to detect the memory leak?
Also AA might be a big culprit. AA in any game sucks up a lot of resources. And is for most cases the first thing to have a memory leak.

As for me. I have only been having trouble when in Pretoria. Lately I have been having my powers lag when in Pretoria. I go to use a power and it takes a second for it to actually work or it takes a extra click. I haven't been noticing any visual lag really. Just lag with power execution.

Hope someone can give you help or ideas?

Now that I'm well rested ...

I think it has something to do with the Protean mission. This morning, everything was fine. Yesterday afternoon, everything was fine. Then things were not fine once I entered the Protean mission. After about 15 minutes, the game bombed on me. I logged back in, and things were fine until I entered the mission.

Maybe it's some oddball combination of ATI's AA (driver v. 10.8, app handles AA, 4X in CoH), my hardware (5850), and the mission.
