    Intel XeSS upscaling technology demonstrated and discussed

    XeSS makes use of Alchemist's XMX AI accelerators for high-perf, hi-fidelity scaling.

    Specifically, Intel says XeSS "uses deep learning to synthesize images that are close to the quality of native high-resolution rendering"
    For once Intel marketing is being honest,unlike Nvidia who needs to keep saying DLSS "is better than native" when native is an image softened with TAA,etc!

    That is my bugbear with DLSS. Not the system itself, but the way it is marketed, and the dubious comparisons posted online, even by 'reviewers'. It is a very competent upscaler, why not just call it what it is? The claim that it 'improves performance' at a given render resolution is untrue and really irks me, but doesn't stop it being parroted online.

    DLSS *adds* workload at a given render resolution, not subtracts it. Not at all unexpected given the process involved. 1080p running with DLSS is obviously slower than 1080p running without it. And no, I obviously don't mean a game rendered at 720p the upscaled with DLSS to 1080p.

    It will work on AMD and Nvidia GPUs as well.

    Interesting. From quickly reading about it I assumed it was hardware dependant.

    So its a software solution that unlike FSR that uses one frame it uses early frames and direction of travel to construct an upscaled image, but if you have there hardware you get even better performance?

    I wonder if Nvidia will suddenly appear to have found a way to give everyone DLSS without the tensor cores being needed?

    Nvidia made Turing so they could have a one size fits all GPU,which could be sold for VFX usage,etc. So they had to find some use for the Tensor cores in their GPUs,so shoehorned DLSS onto it in version 2 - AFAIK version 1 didn't use them! There are also similar methods such as TAAU which don't need specialised hardware AFAIK.

    Yes your right it was put into use as part of DLSS 2.x, I guess it must have a lower overhead than a software solution.

    This might incentivize Nvidia to find a way to create a software solution as Intel have shown its possible (with the added bonus of improved performance if you have a tensor core).

    TAAU is unreal engine upscaling isnt it?

    I would prefer we just got more powerful GPUs for the same price,instead of using upscaling/image reconstruction methods as a crutch!

    Its a terrible time to be a PC enthusiast, I'm thinking of getting a Series X for now and gamepass.

    I like the idea of FSR, XeSS and DLSS are ways to get more performance with less, but I see your point .

    Re: Intel XeSS upscaling technology demonstrated and discussed

    It wouldn't be the first time the use of tensor cores turns out to less important than implied, if not totally unnecessary. Remember when RTX Voice was modified to work without an RTX GPU?

    I have wondered how important the tensor cores really are for DLSS too, whether the operations could be performed on standard shader cores, and what performance would be like if so.

    Vendor-locked solutions are seldom good for the sector, so it's good to see two competing open solutions putting pressure on them. It was good to see the vendor-specific Gsync silliness mostly ended a while back too.

    BIGGEST problem with this hardware ran super sampling craze is the lack of standardization. Microsoft and Cronos need to come-up with a standard software stack or else consumers will be buying cards that have a section of the die underutilized.

    Re: Intel XeSS upscaling technology demonstrated and discussed

    Agreed, but I get the feeling things are starting to point in that direction now. Aside from sponsored games, I expect most game developers would rather use a simpler solution that's available for every customer rather than those using only one brand.

    From a high level, Intel's offering makes sense; use the hardware if it's available, and if not, fall back to another code path. Hopefully, this will extend to using hardware implementations from other vendors too. And hopefully no compiler or dispatcher shenanigans!

    Something I'm not sure of, is how accessible are Nvidia's tensor cores to third-party software? The RTX hardware sounds very application-specific, but tensor cores should be just standard programmable cores as used across many processors nowadays, including those used in smartphones.

    That had occurred to me. Hence the "And hopefully no compiler or dispatcher shenanigans!" bit of my last post. Being the new entrant to this market though, just maybe they won't act like a monopoly here?
