One of the technical issues which has made rise of the Tomb Raider less impressive in terms of visuals was the aliasing it suffered from, on PC and consoles. With the PS4 Pro and the 4K mode, Rise of the Tomb Raider: 20 Year Celebration looks sharper, though it comes at a price as framerate is not always steady. That being said, the 2 other graphics modes (Enriched Visuals and High Framerate) are not all smooth either. it's especially disappointing with the High framerate mode, as it is clearly around 30 - or less - more than it is close to 60. We'll never understand why some people think that unsteady framerate is better than a perfectly locked 30 fps refresh rate.
