Reshade RTGI vs 'real' Ray-Traced GI

there’s a reason why i made the rtgi very minimal and mostly used ambient occlusion

Very interesting and well explained!

This would be glory for those who want the SRB2 RTX mod for 2.2.11 but they dont have gpu or the opengl addon becauz it was deleted

restir partially relies on screen space information, too. though it still utilizes actual ray tracing. spatio-temporal part is one of it's features that allow for decent performance.
just a fun fact.

does the fake ray tracing work with a gtx 1650 super and a ryzen 3500x?

Hey, can you say "get to the chopper!" in a dramatic way? just want to check something.

Hm seems to be like ue4s ssgi (screen space global illumination) maybe not as robust as one of these shaders but similar in how it is only done in screen space

You saved me from wasting money on RTGI, thank you❤

Thank you for clarifying

what a shitpost. not a single DIRECT COMPARISON where you show the same game and scene with built in ray tracing, and reshaded ray tracing. there is NO WAY to accurately compare them between games.

Still, the only game that has good looking "real" ray-traced GI is still Exodus. Everything else is either missing the feature entirely or just applies as a sidenote alongside RT shadows and reflections which are not worth dropping over 30-80 fps on. Hardware RT is gonna continue to be a gimmick for a LONG time.

I hate those clickbait titles.

Ray tracing is nice but performance hit is too big. I prefer 120 fps over better graphics at 30-60 fps.

It is ray tracing. Lots of real-time ray tracers use screen space effects, such as Lumen in UE5. This is exactly like the debates about what is "real VR" back in 2015.

Thanks a lot for the detailed info!

Skyrim with fake RT rashade is amazing.

I like ssrtgi and rasterization. People are just nitpicking to justify a premium for something, ignoring the drawbacks that come with it in gaming. At least we can run ssrtgi natively.

I wonder if games could render the scene twice to improve screen space reflections? Render it in higher FOV and lower res so the edge cutoff isn't as obvious.

It would be interesting to increase the FOV in metro exodus,
making the HUD and UI use a smaller area of the screen,
then using a zoom reshade filter and having at least a bit more screen space out of the player view

Underrated video

i call it the -25 fps option

i clicked for the gravity gun, but i didn't expect this video to include my boiiii Calhoun

I want to hear you say "Get to da choppa!"

Great Video. Great Explanation for sure.

RTGI is garbage, it should be free and even then I wouldn't use it.

didn't know werner herzog ran a gaming channel now

AMD refuses to enable Ray Tracing capability on driver updates for older generations of chips, even recent ones from 2019 like Ryzen 3000 generation... Meanwhile, Nvidia is prodiving driver updates that enable Ray Tracing for GPU's as old as 1060/1070/1080 generation from 2016.... Really shows you how awful AMD treats their own customers... Never again wasting money on anything from this pathetic company... Customers PUNISHED from making a purchasing decision of supporting the company... should have known better to be honest, AMD always had issues even far back as the early 2000's, they never got better at this... AMD is an empty promise

whenever a German says "SS" it hits so different..

Reshade fails in a epic way for 3D shading. I only used it for 2D, color correction and other stuff like that.

I mean even Ray casting counts as Ray tracing, about can use Ray tracing for far more than just bounce calculations for lighting. You can even use it for things outside of rendering if you want...

Newer versions are much better at this, and should be used with subtlety.

Can you do a video about the reflection technique used in half life 2? its not screen space but it can take reflections from objects off screen and out of picture just as well as ray tracing can.

Reshade SSRTGI can be really awesome when properly applied. I saw some comparisons between "real ray-tracing" of Resident Evil 8 and Reshade RTGI, and in my honest opinion the Reshade RTGI is better both in graphical fidelity and efficiency.

that is better or similar to the real "ray tracing" probably more dynamic and cater to many games

People do realize that this is just SSGI, right?

I think my favorite game that I used screen space RTGI on is Portal reloaded, seeing portals emit light that gets bounced off of a surface is really awesome, and because of how they look I always pictured that they would have emitted some light so it's really awesome to see that be reflected in game. That's awesome just really cool to see the colors mixed together if you put multiple portals side by side.

Couldn't you use the temporal frame buffer to offset the inaccuracies?

You know I clicked on this because I ended up in in a very rare situation for myself where I was actually having an argument on the internet, something that I've avoided by writing books with fully irrefutable you know context and evidence and support and rant and what happened yesterday and why it matters and why it's going to fuck us all... I feel like the internet gave me a freebie on that one, somebody arguing that software Ray tracing wasn't real Ray tracing... Like you know, hardware is nice.. but we used to do everything in software back in the day LOL and then I guess we used hardware to do that but direct apis are modern technology, one that we have remodelized I suppose cuz we we started that way cuz that's that would that's how you start I suppose.. what the fuck happened in the '90s? Thank goodness John carmack came to save us all by creating two and a half d and 3D programs that ran out of word processing computers.. and then I suppose he also started all the other things, the software just wasn't good enough.. but you know what it wasn't terrible, cuz I couldn't play putt-putt on my computer, but I could play quake and I can play Jedi Knight.. see why I never actually get into arguments on the internet?

What are you talking about?!? Unreal 5 lumen RT is BILLIONS OF TRIANGLES!!!

RTGI is great to help with shadows in games with bad AO.

AI idea💡- separate program that acts like a single player bot with no clip/god mod on. It effectively covers everything inch of the map and stores that geometry. Based on that information it then applies raytracing. Pre baked pre pass process for any game?

THANK YOU...
I've been doing rendering for almost a decade now using real, multi-pass ray tracing on unbiased engines like Mental Ray, VRay, Cycles and Arnold, and it really annoys me that not only are some people claiming to be able to do ray tracing with some overlay, but that there are also people clicking those videos and actually believing them...

Any effect other than GI able to be done? Reflections, etc?
