The video starts off showing what the screen-space reflections look like. Note how the reflections on the floor fade away when objects that are supposed to be reflected are off-screen (screen-space reflections can only reflect objects that are on-screen, and do so in a generally inaccurate manner). There are also artifacts near the edges of the screen where the screen-space reflection algorithms do not handle well. These are not unique to Control; they are very typical of screen-space reflections.

In the latter half of the videos, the ray tracing effects get turned on. You should immediately notice that the reflections look much nicer, and they reflections stay there even when the objects are off screen. Also, screen edge reflection artifacts are minimal.
