Nice. I've heard that Cyberpunk isn't too CPU heavy so the 3080 Ti makes sense.
Oh FUCK YES. Thank you!!!
This is what happened with The Last of Us Part II.
You´re still mixing up the terms here.
Well, Nvidia's RTXGI seems a lot less costly, and from what I understand, Metro's solution has some similarities.
I don't see how that would work, since screen space reflections rely on information that's already visible on screen. Games already blend ray traced reflections with SSR, but for off screen objects, you are reliant on ray tracing only (or some other fallback, like cube maps).
To be fair, global illumination has been around for years. There were games on the last generation of consoles that used global illumination and as far as I can remember Half Life 2 was one of the first, if not the first titles to support global illumination.
Actually that is not exactly correct. You get BETTER results that realtime raytracing when baking simply before you are not constrained by time.
Well, the act of determining how an object would look from a given angle, is rendering, right? And that's not "free". So you can just render another copy of the scene from the angle at which objects would be reflecting, which is how planar reflections work. But since it doesn't capture the properties of the light itself, it won't work for curved surfaces. And since you're rendering the entire scene again for each reflective surface, it's not super efficient either.
What? They might be able to do SSR and then ray trace parts where there is no data on screen.
Yes, some games use a hybrid, like the Enhanced Edition of Metro Exodus, but it doesn't work how you're saying.
That´s also RT just not per-pixel.
Also uses dumbed down software RT.
Is also a voxel based RT solution afaik.
At best it´s fair to say that even dumbed down RT is miles better than the old static lightprobing while not being as costly as full blown RT.
Yes, I can't recall which, but some games will do screen space for objects further away, or those that would glitch using only screen space information (I think Miles Morales does it, but don't quote me on this).
Not really, not all objects that are reflected are on the screen, or completely visible, or the angle does not necessarily gives an accurate reflection.
It depends how much resources you have, screen space reflections could be considered a "waste or resources" on weaker hardware... requiring a fallback to cube maps.
Except if they keep putting different graphics modes in the games such as performance mode with no RT, then they need to manually add in the cube maps and screen space reflections to fall back on thus requiring the same amount of work as before.
Yes and no. There's no real-time ray tracing being done, so that much is true...but ray tracing brought you some of that lighting. See when all the lights in your scene are static, especially the sun, you can ray trace the lighting and then bake it into the map. That will give you realistic lighting without the performance cost, with the caveat that you can't update it in real time or include dynamic lights.
It's also worth mentioning that these GI solutions like SVOGI or Lumen are not necessarily more performant than comparable implementations of GI that do use triangle ray tracing. They don't really have much benefit on hardware that has good RT acceleration.
