> almost equal to the real deal

Here is our disagreement. For my eyes DLSS is unacceptably blurry (even in ”Quality” mode). You can look at it - ok, but it's only one of the opinions. You can spend 1 minute in google to find quite contrary opinions. Whole your long comment is based on the idea that upscaling is an optimization - you are forgetting that upscaling is a tradeoff.

My main complaint about DLSS ”hype” marketing is exactly about this: do not promise ”incredible quality” when under the hood it's just a pity upscaling. Some HW is not good enough, some games are not optimized enough - it's fair and it's okay, there are things to sacrifice, there are workarounds. Just don't lie.

Respectably, I don't care about "your eyes" - all people are different and that's ok. Nor I care -specifically- about DLSS, obviously technologies are always evolving, it's not that DLSS is the best ever that the concept can be. Also its implementation varies among games.

What I meant to say is that we live at a time where rendering every single pixel all the times is simply a waste of resources - that can be better spent somewhere else.

And you're still saying it's "blurry" - that's not the point. Certainly temporal reprojection will -always- be blurrier than not using it. But you're not considering what you're -gaining- by that blur. The real question is - would it be better to say, have a world with 1 million objects at 4k, a bit blurry, or a perfectly sharp image, at 2k, with 100k objects...

Temporal reprojection saves time that then can be invested in other things.

Lastly. CP2077 ALWAYS uses temporal reprojection. ALWAYS. If you disable DLSS it uses its own TAA instead. If you disable TAA (which cannot be done in the settings menu, but there are hacks to force it) is STILL USES temporal for most of its rendering before the final image.

> all people are different and that's ok

I'm happy to see at least one person on HN can agree with this.

After re-reading your and my comments I concluded that my real issue is lack of the settings in CP2077. I do respect opinion of people who want to use TAA and DLSS, I’m just upset that I can not pick something I like, can’t decide what to sacrifice and what to prioritize.

Your article is quite interesting and I’m grateful for it. Please keep writing things like this.
