Control is pretty but it does have some noticable weak points:

• Raytraced shadows are quite grainy, I think due to inferior denoising in the RTX implementation shipped with the game. You can actually improve this by modding in newer dlls and stuff for the game to hook into.
• Texture streaming is pretty poor, lots of blurry low res placeholders hanging around long after I've gotten close to them. Particularly noticable with portraits.

Besides, pushing the graphical boundary is also important because it leads to greater efficiency as new techniques are discovered. For instance, raytracing is much easier to implement on the developer side than rasterized lighting, which frees up more time to work on the actual game. But if we rested on the laurels of 2017's finest lighting tech we never would have arrived at that point.
