I'm a big proponent of RT, especially RTGI in games like Doom: The Dark Ages and Assassins Creed Shadows. But these RTX Remix mods continue to look, frankly, like shit.
The juxtaposition of early 2000s geometry and low levels of detail with the ultra realistic lighting continues to look weird to me. It's like when people slap 4K textures on basic 3D models. Just something really off about it. If I look at the Call of Duty 2 shots for example, the lighting is 'better', the assets have even been retouched in places, but the room looks oddly bare and the 'better' graphics actually draw more attention to that. It's almost like the enhancement goes too far but also not far enough.
Not to mention these mods seriously mess with art direction, always making baffling changes like turning an overcast day into a sunset. Ironically, the one game where real RT reflections might've been a benefit - Need for Speed Underground - is missing the iconic street reflections in the after. Bummer.
I prefer playing old games now as closely as I can to how they might've looked back in the day, appreciating the limits the developers had to work with on the hardware at the time.
