He's saying you don't need dlss if you just "have shadow maps and non dynamic lights with none changing shaders"

We never said this. Once again someone misquotes/puts insanely false statements into our mouths and pretends to "correct" us.

Again, it's very valid to call out the out of date plugin part that should be relicensed or whatever from Square Enix

It's not a plugin, it's just a shader update.

Going up to 15:30, he mentions how it's subpixel data, which is great info! But does that car... Move?

It has nothing to do with mobility. You clearly have zero idea about why this was shown.

Because once it does, the lighting changes, and the game doesn't have that capability unless baked into the light/shadow maps.

The technologies we spoke about have nothing to do with baked lighting.
Your comment is a perfect example of why we refuse to respond to low quality rants but we'll make a quick example of your ignorant statements.
Forward+ rendering can support dynamic lighting.

For those interested, the direction we'll be taking indirect lighting can be easily deduced by viewing our video on Dynamic lighting, Days Gone, & KCD2.
