Path Traced Global Illumination in Zelda BOTW, Splatoon & Mario Kart 8 (via Cemu Emulator)

1. This is not "full" Ray Tracing like you see with RTX games. This is a hack working with limited available data. But still awesome. Especially in certain games.

2. People saying they aren't impressed by it this far? Wut. It's the single most transformative effect we have seen in decades.

It will be awesome in a few generations when the ray tracing hit isn't so big, but for now they just seem like more of touring/sight seeing graphics effect, like the old Skyrim DOF screen shot ENB settings. Big hit on performance, not that suitable for gameplay, but amazing for screen shots. Until then, faking it looks gorgeous, and plays very well.
Most impressive. Some situations are not ideal though, especially with the overblown bloom.
It's all about "I can't have it so it's meh and irrelevant for me." But as soon as they get their hands on it, they'll shout it from the roof on how great it is.
Remember the "720p is all we need anyway?" from last gen? Or how "4K is an overkill and we don't need it"?

Like a lot of these mods, some parts look really good and others make the contrast and saturation look disgusting and ruin the intended look.
It's worth noting that SonicEther's Minecraft Shaders do have access to far more data than ReShade does.
Minecraft Pathtracing Shaders for example can reflect objects not visible in screenspace and can use PBR data (if available as part of the resource pack) to handle reflectivity, neither are things that ReShade could replicate to the same fidelty as a postprocessing injection (I think).
Looks like shit in Mario Kart but nice enough in BotW although I gotta say Nintendo did a pretty good job faking their lighting.
It's also important to realize that materials matter quite a bit too. These are being applies to games with materials/maps/tesselation not intended to work alongside it. But I do agree.
More than that, the shader is only guessing at material properties by looking at the final scene, so even if used in a game with PBR materials it wouldn't be directly using the information from those materials.
The laval shot and Zora's domain in BotW are great, as well as the entirety of the Mario kart bit, although I feel like the colors in the Splatoon level actually pop a bit more with it off which I like the look of a bit more.
This seems to be missing a lot of stuff that the other modes out there have, there's no self casting shadows or anything, the global illumination seems to be very very toned down, you barely see any light cast when things are very close, things like the moon alin Mario kart isn't casting anything, etc.
I mean it's a dope start but it feels very rudimentary.

Yeah, just screen space. Considering Cemu's graphic pack functionality can freely adjust the aspect ratio in a bunch of games like BOTW without any kind of occlusion culling or other issues, it'd be interesting if someone could trick the game into rendering more of the world and doing fancy techniques with all that extra info.

I want to clarify a few questions from the community regarding the technical side of my shader:
What I'm doing is ray tracing in screen space, tracing rays against the depth buffer (a data buffer that contains the information how far an object is away, as opposed to the color buffer which tells you what color the object has and what you usually see in any game). When compared to DXR, it has several limitations: anything behind another object does not contribute, anything outside the screen does not contribute, backfaces do not contribute. The benefits of this shader is that it can run on every game and GPU and it's a step up from regular SSAO. I hope this serves as a sneak peek at what DXR ray tracing can do and why everyone in vfx can't wait to get real ray tracing for their games.
The lightly lit areas with the Path Tracing enabled are extremely washed out and light in appearance, which is probably a limitation of the shader not being able to properly interact with each game's actual lighting. Makes everything look really weird and disjointed. When its the path tracing alone it looks fine, but added on top of the existing lighting it looks very out of place. If there was a better way to make it interact with existing lighting, this thing might actually be a net improvement in my opinion.
I don't have a card that can do pathtracing but man...just playing my favorite game of all time in 4k/60fps and being able to edit all of the color palettes and stuff is like playing a new title. Having beaten the game so many times I made other adjustments like no weapon durability, unlimited arrows, unlimited stamina and it just feels like a crazy fun, almost arcade action romp. No weapon durability? I'm shield surfing all over the place now. I still think the original design choices in BotW were best, but playing BotW "Remix" is so gratifying.
Goddamn, just now i see we dont need more polygons, its all in the lighting.
Not gonna lie, I don't like Reshade's post processing implementation of "global illumination". To me the inaccuracies and rendering quirks are often evident, light not actually behaving realistically like true ray traced global illumination, and the shader breaking engine tailored depth of field effects as you can see the ambiant occlusion gradient push through unaffected. It's the same problem some engines have when forcing ambient occlusions via Nvidia cards, where the SSAO/HBAO doesn't know when to cull itself and instead renders in full complexity on surfaces through smoke, depth of field, and other effects that are supposed to reduce clarity.
Yeah often the fake one even looks better because it's got a more deliberate 'drama' instead of something more realistic.
That honestly sounds like a frickin' blast, I need to get a decent PC sometime and play around with a few emulators.
