I like DoF as it actually has a purpose in framing a subject. The rest are just lazy attempts at making the game "look better" by just slopping on more and more effects.
Current ray tracing sucks because its all fake AI bullshit.
Ray tracing is not related to AI. Why do you think it's fake AI bullshit? It's tracing rays in the same fashion that blender or Maya would. I think you may be confusing this with DLSS?
"real time raytracing" as is advertised by hardware vendors and implemented in games today is primarily faked by AI de-noising. Even the most powerful cards can't fire anywhere near enough rays to fully raytrace a scene in realtime, so instead they just fire a very low number of rays, and use denoising to clean up the noisy result. That's why, if you look closely, you'll notice that reflections can look weird, and blurry/smeary (especially on weaker cards). It's because the majority of those pixels are predicted by machine learning, not actually sampled from the real scene data.
Blender/Maya's and other film raytracers have always used some form of denoising (before machine learning denoising, there were other algorithms used), but in films they're applied after casting thousands of rays per pixel. In a game today, scenes are rendering around 1 ray per pixel, and with DLSS it's probably even less since the internal render resolution is 2-4x smaller than the final image.
As a technologist, I'll readily admit these are cool applications of machine learning, but as a #gamer4lyfe, I hate how they look in actual games. Until gpus can hit thousands (or maybe just hundreds) of rays per pixel in real time, I'll continue to call it "fake AI bullshit" rather than "real time raytracing"
also, here's an informative video for anyone curious: https://youtu.be/6O2B9BZiZjQ
To each their own. I love ray tracing and think it looks far better than without it. I'm not concerned with how we got here but simply the end result of what is displayed on my screen and it's pleasing to my eyes.
The only game with Raytracing I've seen actually look better with RT on js Cyberpunk 2077. It's the only game I've seen that has full raytraced reflections on surfaces. Everything else just does shadows, and there's basically no visual difference with it on or off; it just makes the game run slower when on.
But those reflections in CP are amazing as fuck. Seeing things reflect in real time off a rained on road is sick.
I agree with this. That makes it even more jarring to me that mirrors inside of safehouses don’t work until you specifically interact with them. It seems so out of place in a game that has all of these cool raytraced reflections except for a mirror you directly look into.
I just don't see them as mirrors. They are video screens with a camera in them. ;)
It's also connected to a performance feature. They can load lower resolution textures for faraway objects. You can do this without the blurring effect of DoF, but it's less jarring if you can blur it.
The cost of DoF rendering far outweighs the memory savings of using reduced texture sizes, especially on older hardware where memory would be at a premium
I think Halo Infinite has a good example of a limited ray traced effect (the shadows) and an example of a terrible DoF effect (it does not look realistic at all or visually appealing)
