Ok so ever since I re loaded AH2 I have been getting this very odd lag spike.  It ALWAYS happens about 15 min after I get into the game.  If I close the game and bring it back up it's as if it reset, it will do it as before, around 15 min in.  Now I had started back up a few months ago after 3 years off, and played for like a week then quit again and never had this problem.  Curious why its doing this, its around a 15-20 sec lag spike, the screen doesn't go black or anything.  It stays at the picture my screen was at when it begins.  After the lag spike ends everything is fine, I am back up to around 50+ FPS and it never happens again as long as I close the game (as I said).  What could be causing this?
