If you can point me towards some (reflections) near the start of the game, I'll take some screenshots and or do another video.
Keep it near the start though, don't mind playing for a bit longer near where my last video ended.
Yes it does. Actually RSR should work with Doom, so I'll grab some screenshots with that enabled also.
CPU looks normal to me.
From 12 minutes onwards in my video, you get some more mirror/metal/glass surfaces.
There are a couple of maps/areas further on in the game which are very orientated around reflections with all the metal but I think they might be a bit further in the game e.g.
