Comment on DLSS Multi-Frame Generation Is Now Easier To Enable On Steam Deck, And It Makes Gameplay Worse

(NSFW warning)
When I had an RTX 2060 laptop, I had the most jank setup for Cyberpunk 2077.
I’d plug it into an older Sony OLED, which only supported low res HDMI input (can’t remember which res, I think 1080p?)
The RTX 2060 would run DLSS quality (for antialiasing) and output 2077 at low-res 60fps, and the TV would use its big ASIC to interpolate it to 120hz, and up to 4K.
And actually, it looked good! It felt smooth! Input lag wasn’t great, but absolutely playable.
I don’t have a PC that can do framegen (3090 now), but ironically, the DLSS framegen demos I’ve seen didn’t have interpolation as good as the Sony. And I believe Sony/Samsung support “no next frame” interpolation, so they don’t blow up input lag.

This is anecdotal but I don’t get all the frame gen hate, I’ve had to tweak it a little bit toward the quality setting but everything looks normal and it’s totally smooth in maxed Cyberpunk at 165 fps

If the rendered framerate is ~60fps (which I’d wager is the case for you), it probably looks great.
Interpolation isn’t psychic; of course its going to look like jello “guessing” what’s between frames at a slideshow pace, especially with the constraint of low latency, without any future frames to use.
But I do have issue with some devs (and some of Nvidia’s marketing) treating it as a crutch. It’s not a fix to 15fps, but it’s a fine way to get 60 to 135 smoothly.

Exactly. Frame gen is trash if you can only hit like 28 FPS before turning it on. But if you are already over 60, it can be fine.
But there is always a latency penalty, and that’s why if you can’t make frame rate without it, you are just digging a deeper hole latency wise.

Ah, right.
That’s sad. AFAIK Oculus developed more integrated interpolation (and, separately, warping) to help with perceived latency:

But that’s like lost magic these days.

Yeah with frame gen off it’s still like 110-120 with dips in the high double digits
