Honestly, I'm more impressed and excited by FSR 1/2 than DLSS, exactly because of laptop & iGPU gaming. DLSS is just for rich folk with latest toys, while FSR is for everyone, even iGPU plebs.
I have desktop that plays everything just fine maxed at 1080p. But just past year or so I spent 300 hours in Valheim, much of it on laptop. And while Valheim is already low graphics game and ran fine, it's just a showing that gaming on lower end hardware can still be fun.
And if FSR can provide 30fps at any reasonable graphics settings at 1080p - all more fun! For low end gaming, all that we need is graphics details that don't interfere with gameplay. If game is fun (good story, good mechanics, etc) I don't care about graphics, I just want to play. And I rather play on laptop than not play at all. And rather have 30fps with FSR then a slideshow without it.
So all the nitpicking and trolling how suddenly people accept low quality is foolish. There's games you want to play for eye candy, then there's games you just want to play. Period. And you'd do anything just to have them playable. (Hell, my colleague played Valheim on Intel iGPU at 720p low with 15fps, and was happy, as he couldn't get anything better at a time)
So to cycle back, that's what makes me happy with FSR news. It is going to help exactly the right crowd. Ones that just want to play. Elitist crowd that frowns upon it can happily buy a 1000$ GPU.
