Sod it seeing as this out on PC now may as well give the old dog some new life.
PC port is pretty solid. Here's what graphical bells and whistles there are.
Resolution options are same as III and Black Flag so what ever is avilable on your system and constrained to 16:9 so multiples are fine for multi monitor setups but 16:10 and 21:9 will be windowed and pillar boxed respectively (though there's a workaround over at WSGF already). Also yes that is actual borderless window support out the box in an Assassin's Creed title.
Environment Quality has 3 settings, affecting draw distance and LOD transitions for foliage, buildings, ships and the such like.
Texture Quality has 2, Normal and High with High using around 1.2-1.4gb of VRAM at 1920x1080 with everything else dialled up.
AA sadly is on FXAA which itself has pretty poor coverage but downsampling is an option due to lower performance cost than Black Flag.
Shadow Quality has 4 settings, Off, Normal, High and Very High with higher resolution shadow maps the further up the settings but transitions are still about 20 foot around you.
Reflection Quality has 3 settings, Off, Normal and High. These effect reflections in water and such (oddly it didn't appear to effect the reflective surfaces in the present day office).
Aniso is available in 4 factors, Off x4, x8 and x16 and works as expected.
Ocean Quality has 3 settings Normal, High and Very high and effects the physics like waves and such when out on the ocean.
Post Effects Quality has 2 settings, Normal and High which seems to alter the effects like snow flakes and leaves.
Motion Blur is On or Off and is camera orientated.
Ambient Occlusion has 4 settings, Off, SSAO, HBAO low and HBAO high (I'll post some pics bellow).
God Rays and Volumetric Fog both have 2 options of On and Off and work much in the same way the did in Black Flag (though no Nvidia tessellated God Rays this time).
And Vsync is On or Off. Haven't tested fully but I think it's triple buffered at bloody last but I'm taking advantage of borderless window mode so eh.
So over what I played on 360 late last year it's quite the upgrade as you'd expect with performance being a solid 62fps (same framerate cap as the past couple of games sadly) at 1920x1080 and even downclocking a single 780 and 2560x1440 only went as low as ~55fps. Reflections for a start aren't the low res cube maps from the console version but do appear to be some form of Screen Space Reflection like found in Black Flag on PS4/XO/PC. Also Ambient Occlusion if I recall was lacking from my time with Rogue on 360 and really that boost to contact shadowing give's the flat image much needed depth. Here's what each setting looks like in practice.

While not as accurate as Nvidia's HBAO+ in Black Flag to me that's still a great enhancement.
Only had a muck about until the mid point of Sequence 2 so haven't got to New York where the worst of the pop in was but yeah solid port so far but will have a better play around tonight when I get in from work. So while Rogue doesn't have some of the Nvidia goodies like HBAO+, Percentage Closer Soft Shadows, TXAA and Tessellated God Rays the performance gains are very welcome.
