While the PCI-E tweak doesn't apply to my mobo, the profile tweak added a nice 10 fps.
Still only about 50ish fps in a zone with a handful of other players, such as a city early in the morning like my current testing.
But better than 40ish. I kept myself locked down to 30fps just for consistencies sake because of that. Felt really smooth going uncapped and running around my house, haha.
