The PC version will have much better visuals than before. And antialiasing is much much better than before (smile).
We utilized compute shaders in one more place (2033 already used compute shaders). Regarding the performance, the interesting thing is that we have improved graphics in almost all places, but the performance is still on 2033-level, and even better in many places. Actually, until you turn on tessellation/displacement it is the same. That's because a lot more content is tessellated and displaced comparing to 2033. Regarding features, I'd rather say that we improved all the features like added Bokeh for DOF, implemented physically based SSAO or much better reflections.
