    If you remember a video where you have seen this i'd be interested.
    For me it's mostly abrupt changes like removing / adding blocks that feels unacceptable.

    It's not as bad as I remember as the geometry is still crisp, but the textures/lighting is struggles with fast movements (kept to a minimum here because they are observing the pretty lights).

    Thanks. Yeah, that's bad. They may improve it, but imagine characters moving around... Probably we won't see this level of lighting in action games - likely worse than current SSAO/SSR artifacts.
    Ofc, texture space could fix this in theory. (But wouldn't help much with removing / adding blocks.)

    Reprojection for statics works perfectly with only camera position delta indormation. MV are needes for dynamics only, which are a smart part of the scene in typical MC gameplay, thus why the artifacta arent more egregious.

    Watch the digital foundry interview and they discuss how temporal blur is worse than it could be because they hacked a solution for tracking objects frame to frame that is not as robust as motion vectors.

    That is my memory of what was discussed. I know they didn't have motion vectors so they created some kind of object tracking that will be replaced or improved for the final release. I believe that was discussed in the context of DLSS, which I believe requires motion vectors.

    So it looks like World of Warcraft will be getting raytraced shadows soon. The option with 3 quality levels appeared on the latest alpha.

    No.
    All Fortnite cinematics/trailers since the John Wick one use RT.

    Thanks for the new UE 4 documentation link. The interactive pictorial definitely answers a lot of questions regarding rasterization vs real-time ray tracing.

    For the difference I found ray tracing essentials having one of the better descriptions around.

    Oooh, shiny. Also proves my pet peeve I have with UE5. Yeah, sure, unlimited polys are neat, and higher poly models for grass and trees are really needed because they often stick out like a sore thumb in today's games. But are unlimited polys really needed? Nah, look at the UE4 scene and that marbles demo, lighting and good art assets sit there and make more of an impact than unlimited polys do. Mmmm, sharp indirect lighting, soooo good.
