Hard disagree.
RT can give a level of immersion that's simply not possible with raster lighting. This mostly has to do with how dynamic lighting plays off of materials and how the accuracy of GI and shadowing plays out over time.
It's like the concept of emergent gameplay but for being immersed within game environments. Emergent immersion. Sure. I'll call it that.
It's why old and lo-fi games can become completely transformed just by adding good RT to them. A few cases in point:
- Minecraft bedrock RTX maps
- Half Life RTX mod
- Mario 64 RTX (sm64rt)
- Doom RT (prboom)
And when modern games use good RT, it takes the immersion to a whole new level as well, such as:
- CP2077 with highest RT
- Metro Exodus: EE
- Indiana Jones Full RT on.
It's not even something you can see in screenshots, because "you have to be there" in the game yourself, over time, to experience it.
Good RT brings the world together as one cohesive simulation with the lighting being done in real time, rather than a bunch of pre-baked fakery that can't quite get the details good enough to sell the illusion.
