Soldato
Gone through multiple scenes with RT on Vs off on a 3080 and I can't tell the difference other than the framerate halving. In some specific area like the water it's noticeable but I don't think they needed RT for that, they just slacked on the non RT water. Half life 2 has better water than cp2077 non RT .
However I can see a difference with DLSS on (more blurry, less sharp textures, fuzziness on fine thin objects), so it's DLSS off and RT off for me
You could ditch the RT lighting and shadows and keep the reflections on for a decent boost in FPS
