    For there being no "night and day" differences, at least in their little widget for Rage 2, the difference is relatively massive to me. Blurry-ish presentation versus not so blurry presentation. Most noticeable with the vegetation. Textures for terrain slightly less so while the weapon sees the least noticeable improvement. That's good for me as vegetation and terrain textures in games can drive me nuts.

    I suppose it depends on which effects you implement, but AMD said 0.x - <2 % difference in Borderlands 3

    FidelityFX Contrast Adaptive Sharpening (CAS) is now freely available. Created by Timothy Lottes (who created FXAA 10 years ago while at Nvidia) :

    Holy cow, that difference is amazing, on the level of something that DSR would bring about.
    If this were navi only, I'd have sold off my cards yesterday.

    It'd be great if this could be an injectable like SMAA/FXAA. Though it might be something like TAA that can't be used without more support from the game engine.

    Would this be useful to compliment DLSS to counter some of the blurring.

    Yea they said it has to be implemented by the devs, taa is exactly the use case they suggested it would be ideal for.

    The radeon image sharpening works with everything though, although I haven't heard anything about it really yet.

    It's currently limited to Vulkan, DirectX 9 and DirectX 11 (also requires RX 5700)

    So is this a feature implemented in the driver or is it an ingame option ?
    Edit: it's ingame I should have read the article first ;)
    would it be safe to say its like nvidia's digital vibrance but selective ?

    And DX12 ;)

    Edit: now I'm a bit confused
    Your second sentence refers to amd's image sharpening, what's the first sentence referring to?

    Fidelity FX is a developer toolkit from AMD for contrast adaptive sharpening (and upscaling?).

    Radeon image sharpening is a driver feature on the RX 5700 series for contrast adaptive sharpening and upscaling.

    Driver RIS and FidelityFX CAS use the same technologies. The reason it's also available for the developer to integrate, rather than being driver only, is that the driver implementation necessarily can only apply it on the final presented image the game sends for display. That often looks fine, but it might not be optimal depending on what's being drawn and how it's being drawn.

    The best case is the developer integrates it into the right place in their renderer, usually somewhere in the post chain that correctly considers colour space, text and UI rendering, etc. If that happens and a game integrates it, the driver uses app registration and other mechanisms to disable RIS for that title, so it doesn't happen twice.

    CAS integrations were some of the last things I worked on at AMD, and the feedback from developers was very positive on the whole. Where it didn't work in eval were sensible cases that tended to be technically related, rather than quality related. Things like the game already had a well optimised content-aware sharpener tightly integrated into an existing pass.

    One of the key selling points, and a real feature, is the fact that it's completely open and MIT licensed, so developers can do what they want with it. Pull it to pieces, optimise it, integrate it however you see fit, use it as a building block for something else, whatever they like. No black box, no silly licensing, no silly deals. Just "here's some cool tech we invented that you might like and it's free".

    ???

    OH! You're back at IMG? Congrats? I know you likely can't talk about anything, but I do wonder if there's something exciting going on there that drew you back. :)

    Do you actually have a Neon 250? I would buy it from you if it's for sale (not kidding).

    Under pressure from AMD (no doubt), NVIDIA introduced a new post process sharpen filter that is both faster and of better quality than previously possible, it works for all NVIDIA cards, and supports all APIs.
