    Nvidia GimpWorks has made me very wary of anything NVidia puts out that runs on all major GPUs, but has a separate code path for Nvidia GPUs.

    Too little, too late.

    I think without sharpen, NIS and FSR/EASU pretty much generate the same result. While it's nice that Nvidia does something open, it looks redundant to me. Their sharpen also seems very inferior to CAS/RCAS, as it gives very aliased results.

    If AMD did one thing right for gamers in recent years, it's CAS. A sharpen filter that introduces hardly any ringing and aliasing while being very fast = full of win. Love it combined with DLSS.

    For testing scalers/sharpeners I recommend VIFp (preferably this version). It doesn't punish for oversharpening only for artifacts from it and overall it's a better metric than SSIM.

    I'm outa my depth here, but some things I noticed in the source:

    -FP16 Support
    -Optimization for Nvidia/AMD/Intel, though right now the setting is a placeholder/doesn't appear to do anything, as all the values are exactly the same for each vendor.
    -Still HLSL only.
