Pretty sure Unobtanium turns on more ray tracing along with higher resolution textures. Problem is that there's no clear description of the various settings and when they do / don't use ray tracing. Or maybe Unobtanium increases the cutoff distance for RT calculations?
Anyway, I'm a firm believer that RT can improve image quality, when done properly, but doing it properly requires a lot more RT than just doing some shadows, AO, or even reflections. Doing full global illumination (meaning, all the lighting and such calculated via RT, i.e. what Nvidia calls path tracing) probably requires at least 500 rays per pixel, and even that isn't really sufficient. (RT in Hollywood movies are probably closer to ~10K or more rays per pixel, and they're doing that at 8K these days.)
Oh, there's no question about that. What I've always believed is that while RT and/PT are the future, PC tech isn't advanced enough to properly use them yet. When it's advanced enough to use RT and/or PT smoothly at 60FPS at 1440p or 2160p, then (and only then) will it be worth it to me to turn it on. This is because I honestly believe that games are beautiful already without it so it's not like anybody's suffering if RT/PT isn't turned on.
Hell, growing up, I gamed on an Atari, ColecoVision, Intellivision, TRS-80, C64, NES, Genesis, N64, PS2, PS4 and PC. I guess that since I've been gaming so long and have experienced pretty much every level of graphics, what matters most to me is the game's content. I don't think I'm unique in that regard when you consider how popular mobile games and online MMORPGs are despite the fact that they don't even come close to matching the graphical fidelity of modern AAA titles. A game is either fun or it's not, regardless of how pretty the graphics are.
There are lots of things in CP77 where the difference between path tracing and even RT ultra is quite substantial, if you know what you're looking for. It doesn't fundamentally alter the game, but it does look better / more accurate. Same for Alan Wake 2. Avatar isn't doing full RT by any stretch, even at Unobtanium, but it does more shader calculations per pixel for sure. A lot of those calculations are just going to be the same as the faster approximations done at ultra, though.
I absolutely agree with you but it's like I said, our tech isn't there yet so it's horrifically expensive and its performance generally sucks buttocks. Like, just think of how many people foolishly spent over $2,000 for an RTX 2080 Ti mere months before the launch of the RTX 30-series cards. At the time, the RTX 2080 Ti was "
the pinnacle of RT performance" but, as we look at it now, it still sucked, despite the insane price.
When the RTX 20-series was first released, Jensen Huang said his (in)famous words:
"EVERYTHING JUST WORKS!"
Here we are,
five years later (which, as you know is an eternity in PC tech) and it's still not true. How he managed to convince so many just blows my mind.
