The FPS drops happen often inside of any town or near any buildings
When walking/running through areas like fields or wooded areas it doesn't happen often but it does happen
The game becomes unplayable near towns or buildings due to the FPS drops and occasionally crashes the game because it drops so much, this problem did not exist in update 1.06
