Thanks for the reply, 760 Overclocked is only able to achieve 60 fps (not even locked...) on Low, this is very very weird.
There is some optimization issues going on for sure, plus my CPU isn't used more than 25%.
That is really odd. Might just be a bug on certain cards in that case. I found the most costly settings to be foliage distance and density, so maybe you'd be able to get some other things a bit higher for now if you kept those as low as you can?

which doesnt have any effect!
Just got some new info. Apparently you need to make the user.settings file read only after you save changes to it. It does mean that you won't be able to change settings in game I think, but apparently that's the solution.
Just tested, definitely works (on the opening cutscene).
