Has anybody else been experiencing frame drops since the 3.5 update?

Before the update in all situations I got a solid 60fps (locked) except for the 50+ player Odin and S rank where I might drop to 50.

Now in towns that are no busier than usual I get around 45fps.

No reason why I should be getting such low FPS with my specs...
