How about this "Freesync 2 HDR LFR"? Also, does anyone know how the performance (input lag) of LFR differs from old-school V-sync? Seems like each one would result in the same lag whether the previous frame is duplicated or next frame is delayed?

I imagine it adds some input lag but it only comes into play at framerates below 30fps.. at that point both G-Sync and Freesync turn the motion such into a mess without it that you'd probably accept significant input lag to prevent it. It's more of a like a "safety net" when the FPS dips below 30 to maintain smoothness than something you want to be running at all the time.

Why not keep it simple and just make it "FreeSync HDR". Companies love there version numbers.

I guess they think version 2 isn't enough to call attention to it. So now it requires 600, not 400? That will make the monitors really expensive 🙁

Those glasses companies are going to love us gamers in a few years.
