Some effects can be faked well with pre-computation but important cues for dynamic object interaction like high quality dynamic ambient occlusion are not easy to fake. Other tricks designed for 2D displays don't hold up as well in VR. I see a lot of object interaction difficulties with novice VR users that I think can be helped by better rendering, although there are issues that will also need better display technologies to resolve.
