GPU Ray Tracing Performance Comparisons [2021] *spawn*

So, no real time GI at all? The voxel GI is an afterthought, too...

 

No, I'm not. There obviously and objectively is a difference.

The church scene looks a lot less bleak, sure. But it suffers from less-than-impressive assets as well, from what I've seen in the video.

I don't understand what you mean by no real time GI at all.

 

What does RT has to do with assets or - dare I even say it - art direction?

The takes on how RT in general sucks because a game which is using it wasn't made by Rockstar or Naughty Dog with a 1B USD budget are getting really tiresome.

 

Yeah Alex could’ve picked a better picture for the tweet. The bus in particular looks terrible.

The actual video is much more impressive but the low fidelity of the 3D assets is still obvious underneath all of the amazing lighting.

 

Lets pray for mid gen refreshes again, which pack RT as capable atleast as turing/ampere.

 

Hm, now you're telling me things I did not even say in the first place. Maybe take a step back and re-read what I wrote: That RT(GI) looks good.

 

Speaking of Rockstar -

Not sure what this would mean for the PC version exactly however, but we may get another data point in a month or so.

Presumably given the above I'm guessing GTV VI would likely also have ray tracing support.

I'd guess that a PS3 generation game could recieve ray tracing and alot of other features yes. Its nice and all, but where is GTA6

 

What I wrote: RT(GI) looks good in this game. Other visuals are not really able to support the lighting in a way that the graphics look very good (in a homogeneous way).

edit: Ah, I wasn't catching the meme-ness of this. See below.

 

Ya I understand. It was just a meme from a discussion where she repeatedly tells him he’s saying something he's not.

 

"Got ya"

 

Spoiler

RTGI worth enabling just because it fixes the crap with light leaks.
Wish there was such option in every game.

 

Can anyone test the performance hit of RTGI vs shadows and AO on an AMD GPU? If the performance drop is similar as on Nvidia I really wonder why Techland didn't opt for the GI on consoles.

 

Computerbase has done it: https://www.computerbase.de/2022-02...t/2/#abschnitt_die_performance_von_raytracing

 

Looks like the fixed overhead of BVH management is dominating the result. Casting additional rays is cheap on GeForce.

DX12 and DX11 performance are remarkably similar at least on a fast CPU.

 

Ya those CB tests show GI is substantially heavier. Console RT choices make sense.

 

I think it may be a problem with games that don't use some accumulated form of bounce lighting over multiple frames, like the RT-only Metro Exodus does. Without enough bounces you get that crushed areas without indirect lighting look.

 

@Phantom88 Ray tracing just likes vastly superior. It's indisputable. I'd play dlss performance mode to get ray tracing, vs playing native res with non ray-tracing.
