I was impressed with it in alan wake 2 since not only did it have better performance than the denoisers but it also made lower upscaling qualities look more bearable ( mostly better preserved detail)
every instance of ray reconstruction has made the image look like an oversharpened oil painting in motion, i absolutely hated it. all these games with blurry ass taa and dlss, dont need ray reconstruction to make it 3x worse, even with the small performance and visual enhancements otherwise.
@@Meansoduck i saw some of those issues in cyberpunk but not in alan wake 2 , it also looks worse the lower the resolution , to me at 1440p it looks good and enhances the image compared to the normal denoisers which also have those issues
@@Meansoduck it has become a little better and of course this will get better. the shimmering and flickering is way worse than a bit oil paint look. some people cry way too much, probably all AMD users
Honestly, I'm still just waiting for someone to give Mass Effect 1 the RTX Remix treatment. I've even dreamed of it happening....
Ray Reconstruction looks brilliant but I agree with the closing statements. RR seems to make some reflections (at least in my Cyberpunk Phantom Liberty playthrough) sharper or cleaner than they should be.
Alan Wake 2 has the same problem that Cyberpunk has. Ray reconstruction is great for geometry but it makes faces look weird if they are not up close to the POV.
I wanna crawl under Jensens desk for greenlighting RTX Remix as an entire tool rather than just a demo to show off why "you should care about RT". The only issues is that right now its limited to older APIs exclusively and therefore heavily minimizing the potential games to be "remixed". I sincerely hope they find a way to open it up to more modern DirectX versions
Sadly AMD and Intel don't have their own form of Ray Reconstruction
YET.
Both created frame gen, Ray Reconstruction is for sure underway.
@@hicarodestrui I wouldn't doubt, both Intel and AMD have AI cores now
But goddamn it, when will they start using ML? Disoclussion artifacts are still terrible
@@tigrankhachaturian8983 intel is using ML, just AMD that is behind.
doesnt look good enough yet anyways
i swear ray recon makes lower level dlss presets look better as it used to be the case that ray tracing would use the base resolution
At its core, i think RR will always show some degree of sharpening or edge enhancement. Correct me if i'm wrong, but i liken it (in my own mind) to running a set of photoshop actions on a super noisy photo. Gaussian blur followed by a few rounds of clarity boosting, unsharp mask, contrast enhancement etc. I know it's 'using AI' to do more nuanced things but it's always seemed kinda vague as to how it enhances things like reflections more than character faces. As far as why it integrates better into Alan Wake PT, i think the more painterly/softer art style allows for the RR clarity boost without being obvious and i'm sure Remedy tuned it to some degree. I would imagine there are config values that let you customize its behavior when implement it into a project but i'm not a dev.
It's definitely true that RR (and other upscaling techniques) will always have some level of artefacts, but these won't necessarily resemble sharpening/edge enhancement. At its core what these models are attempting to do is make a prediction of ground truth from a limited set of data - they could equally as well over-smoothen rather than over sharpen.
Better models should be able to get closer to the ground truth, but within a level of model quality you might see some tuned to over predict edges and detail vs some that over smoothen them (and there's probably an element of postprocessing in there too) - it's more of a design choice than a limitation on the process itself
you are thinking of it like photo editing where you are trying to solve noise with screen treatment of a single existing image, but RR like DLSS is more about selecting the representative data from the bucket of samples that where accumulated temporally. that means you arent just treating the current image, you are looking back at the previous 4 or 8 images and trying to reconcile what information from them is still relevant and re-usable.
RR improves quality in 2 ways.
1. the ML approach should just be better at the task than regular denoisers unless they were meticulously hand tuned on a per game, per effect basis.
2. you are no longer doubling up on temporal accumulation as you are no longer feeding a temporally denoised image into DLSS to be temporally upscaled, DLSS + RR does both denoising and upscaling in a single step so you don't compound your sample re-use.
*cries in AMD card owner* My 7900XTX wheezes and dies in Portal RTX.
Damn I suspect duke 3d original is a little to old for this...😕
Yeah, Quake had good results because of the fact that most of the image is 3D whereas Duke 3D is uses a lot of sprites. Could probably still be done, especially if someone remakes the assets in 3D.
For Deus Ex, modders had to make a new renderer (the Echelon Renderer) to make it work with RTX Remix. Maybe something like that is at play in Duke 3D as well.
@@brainycabde It's pretty likely that modders will just remake those assets
Remix gets ray reconstruction before it gets support for games. It only works like 5 games.
The people don’t care about this ray casting nonsense, most people don’t understand it and can’t even tell if it’s on or off.
Speak for yourself
@@Fusion05 i speak for the people
LMAO
You are alone in that, most people understand it and most people can tell when its on or off
Its the only way forward anyway
Dude I own an AMD flagship card and I'm not this deep in denial.
@@HappyHubris lmao
AMD gpus are awesome i just wish they had better RT performance
excited for RDNA 4
