Internal resolution isn't locked, that's for sure as raising resolution also raises 3D models, but it seems like it's certain percentage of selected screen resolution. That's why I didn't use word "locked" but "lower" at made key point.
At least for me this definitely looks like 3D models are rendered at lower resolution and upscaled with filter, also considering how blurry everything is and even with forced highest possible AA and AF image quality stays identical

This is probably to keep much thicker outlines and with blurrier visuals it does look bit more like painting, but personally I don't like it at all.
