    Is this to be available only for the regular editions, or for LTSC as well?

    Good question (I tend to believe yes, until LTSC switches over to the next big build sometime next year), but I'm also curious about this:

    Will current DXR hardware (as in, RTX Geforces of Turing) support Tier 1.1? Or is this reserved for next year's RTX cards?

    I have a feeling Nvidia hasn't been hurrying with Ampere to have all of this fully implemented. They probably worked together with MS to develop this. Let's hope AMD was there as well since MS probably had the new Xbox gen in mind when developing this.

    Don't have much understanding, but it seems to me that current cards should be supported. Next-gen might(should?) be more optimized.

    Curious about that since Nvidia's blog seems to indicate some level of conformity with microsoft's software changes. But we should know more fairly soon.

    I believe these are purely software additions and do not need a hardware change.

    That would certainly be jolly news for current RTX owners.

    Then again, sometimes software changes and new features may require more performance from the hardware. Just because you have an RT core, doesn't mean it's fast enough to process (with adequate framerate) more advanced ray-tracing down the line, even if were to be strictly speaking "compatible".
