    Particle effects in Control look fine from what I’ve played.

    It's possible that they use something else then. It was in the digital foundry video for DS, I believe it was said there that those artefacts were inherent to DLSS type of upscaling, maybe control came out later

    Yah it gives a formula: mip bias = native bias + log2(render res/native res)

    I guess you could just use native lod = 0

    Edit:

    Edit2:

    in the case of each DLSS mode log2(render res/native res) =
    DLSS quality = log2(1280/1920) = -0.584962500721
    DLSS balanced = log2(1114/1920) = -0.785357078268
    DLSS performance = log2(960/1920) = -1.0
    DLSS ultra performance = log2(640/1920) = -1.58496250072

    Still not sure how you'd know what the native bias is to make adjustment manually. I guess you can just set this as the LOD bias in nvidiaprofileinspector, assuming the game isn't making this adjustment already.

    There's nothing inherent to DLSS in game engine not providing the DLSS with proper motion vectors for particles.

    Most such bugs are due to corners being cut on the engine side during DLSS integration with the game. Maybe the engine doesn't do that at all or maybe it does it in a fashion which isn't easy to integrate.

    He's right though. In Death Stranding, those sparks from the container on his back look hella muted or even gone with DLSS.

    Control is older and it uses DLSS 2.0

    I wonder if they will be using the new Triangle Position Interpolation unit for motion blur effects.

    Agreed. At the WCCFTech link there is another video that gives more detail on the game though not much better.
