    They may point at their iGPU install base and feel a bit bigger than they are - and I suspect that's the main reason for a DP4a path alongside their tensor-clones.

    I wonder if Nvidia will suddenly appear to have found a way to give everyone DLSS without the tensor cores being needed?
    With the amount of silicon dedicated to tensor ops in the arc arch, Intel has a lot of room to make this hamstrung even on competitor GPUs with tensor stuff

    Credit to Wccftech, they've got a nice interview with Karthik Vaidyanathan - lots of interesting info IMHO:

    Re: Intel XeSS upscaling technology demonstrated and discussed

    It all sounds very promising on paper - the benefits of DLSS2.0 (improved clarity over native res for fine details, decent low res scaling), while being GPU agnostic with support for older models, and generalised approach (so it doesn't need to be "trained" like DLSS, and operates more like FSR in that sense). I guess we'll just have to wait and see if this is all true, and what performance benefits it brings to the table.

    Assuming it is true, even if the performance uptick isn't as impressive as FSR Ultra Quality, or DLSS Quality, I'd be happy to maintain image quality and gain a lesser performance boost.

    It will be nice if all 3 approaches can have their own niche, so users can decide themselves where the sweetspot lies for them in terms of quality / performance trade off.

    Re: Intel XeSS upscaling technology demonstrated and discussed

    It still needs to be trained, but like DLSS 2, you can generalise models produced from the training (hence why you can swap DLSS 2 models between games and they still work for the most part). However it's certainly good that they've clearly gone for generalisation from the start and having the DP4a fallback is also good - seems to be a more 'benefit for more gamers' approach than NVidia's (unsurprisingly). Though of course, they're asking devs to start on the Intel specific acceleration first before letting them work on DP4a, so there's still going to be a bit of a hardware bias (I'd imaging targeting DP4a from the start would be better for everyone else rather than adapting something Intel specific later).

    Me and a mate were comparing the images in the video,and in some instances the 1080p side look pretty bad,even for a 1080p images(the upscaled image was showing details "lost" in the 1080p one). I think we might need some more independent confirmation of image quality!

    Where those details lost in a single screenshot or not present even in motion? If the former then that's exactly what temporal (super sample) methods are there for - you recreate the detail from accumulating previous frames, even if a single frame doesn't have the detail.

    Pause and have a look at some of the text for example. Even with some of the DLSS videos,the 1080p footage used didn't look as bad. This is why I won't take the demonstration video as gospel truth quite yet,until some more indepedent tests are done.
