Ghostwire Tokyo | Ray-Tracing Comparison | RTX ON/OFF

[B-KR]

Once you know how screenspace works, it becomes very distracting. RT fixes that completely

[SMGJohn]

People forget that regular raster shadows, colour bounce and reflections can indeed be as good as ray tracing, but the time, effort and resources needed to implement it is massive, even today Unreal Engine and likes of Cry Engine have been developed for 15+ years and still struggle to add these features because they are massively taxing on the GPU, it gets to a point were ray tracing actually is less computational expensive. And complexity in graphics also add more bugs and inconsistencies that are difficult to fix.

Remember that in most games even today, light boxes are still manually placed, most light sources do not emit light by themselves, but are just models, while a real light source is added, this is duo to optimisation, with ray tracing all you need is a texture that emits light in any shape or form and no need to think about more, if you want a room to be less lit, you can adjust the the individual strength of these light sources, or if you want colours differently you can add different colour lights, as of now with raster lighting, to change colours in a room based on lighting, a lot of complicated methods are done to achieve it.

Such a good showcase of RT! The image is so much more stable and coherent with it enabled.

Tbh, i never really "got" how ray tracing actually affects the graphics of a game. Besides just "fancy lighting". And i gotta admit, the fact that reflections persist even though what is reflected is no longer in the fov of the camera makes it so much more realistic.
The example of the thumbnail is perfect to show where the difference is

RTX is the Nvidia product name for consumer PC GPUs with dedicated ray-tracing (+DLSS) hardware.
When ray-tracing is on a non-Nvidia hardware like AMD GPUs (PC, console) we can say RT, not RTX.
Many people seem to refer to all ray tracing as "RTX" regardless of platform these days.
(just an observation, not regarding this video's title or anything. Here it's clear we are seeing 'RTX' in terms of running PC version using Nvidia RTX GPU).

3:49 Why Ray-Tracing OFF looks better?

[Rubicon]

It's beautiful work but I feel that, although RT can produce nice results, in many instances reflections and shadows are way too sharp. It creates a very cg look because it looks as though everything is covered in chrome rather than there being nuance in the specular roughness (Entire wet streets entirely wet everywhere rather than covered areas/doorways having dry patches) or shadows are way too sharp like the basket on the trolley. The kitchen was a nice example of this working well with rougher reflective surfaces. It demonstrates you can't just turn it on and it looks great - it requires a lot of time, resources and art direction to tweak shaders. No small task when recreating a city!

No es por nada pero me parece increíble como Ps5 demuestra tener RT casi a la altura de un PC de gama alta

[heorgiy]

if “Raytracing” is used everywhere, it can spoil the visual scene that artists created to highlight certain objects or details

[BERSERKERDEMON]

Love your channel (better than Digital Foundry at this point) Just so you know "Some shadows HAVE no reflection" instead of "HAS no reflection" (because shadowS in plural)

[saveloy]

i like rtx and i respect rtx especially used in retro games but for modern ill rather have fps boost than the rtx on maybe in the future for me

[josuita]

The benchmark is made on PC? With MAXED out settings?

[josuita]

Can you do also the comparison on A PLAGUE TALE REQUIEM?

[NBWDOUGHBOY]

Why does the Reflections look better with the rtx off at 1:50

[dirad]

Developers have made good reflections without RTX but forgot about mirrors 😬

[killermatico]

va cargando los reflejos conforme mueves la camara. eso es cutre, aunque no tenga rt eso no debe de

[Rostovgenchik]

ElAnalista, do it please compare between versions of The Ascent 🙂

[keremmantam]

Hello bro, they increased the speed of the Ps3 graphics chip. can you do framerate tests for games?

[thn]

Why the rtx off has that weird white reflection? I never had that on my pc

[gabriellubo]

Alguien sabe si tendra photomode? esta increible las graficas
