Comment on DLSS Multi-Frame Generation Is Now Easier To Enable On Steam Deck, And It Makes Gameplay Worse
AngryMob@lemmy.one 6 days agoYour concept of halving the framerate is wrong though… If you’re natively at 100fps, each frame takes 10ms to render. Enable frame gen and you get 10ms of additional latency (plus the latency from generating the frame itself which is often 1 or 2ms). Thats a lot less than you would claim, which would be 20+ms from feeling like 50fps.
Its more comparable to the latency from vsync if anything, which people have been using for decades even on 30fps content.
There are plenty of tests that show this online, you dont need to even napkin math it out like this.

What? Your numbers are right, if you were running the game at 100FPS it would take 10ms to render a frame. Plus your 10ms of additional latency from holding the frame. 10ms + 10ms is 20ms.
If you were running the game natively at 50FPS, it would take 20ms to render a frame. That’s the same number. The total input lag from rendering is identical. Add in the slowdown from your GPU rendering the in betweens and its even worse.
