Lag/stutter, one possible cause identified

Title: Game running slow since final wipe - possible contributing factor
Reproduction Rate: Intermittent, frequent
Blocker? No
Details: Reduced frame rate and responsiveness experienced sporadically every time I play. In at least one scene (South Drachvald Spur) this is very directional; frame rate was much improved when near the edge of the scene and facing toward the border, game became progressively more sluggish when turning to face away from the border while standing on the same spot. However in Eastmarch game was sluggish regardless of location and orientation.
Steps to Reproduce: Normal gameplay
User Specs: Alienware M17x-R4, i7-3630QM 2.4GHz CPU, 12GB RAM, Win7 SP1
