This is for multiplying your fps by 3x or 4x, but the input lag, ghosting, stuttering, and other issues make everything worse. Overall I’d recommend sticking to lossless scaling at 2x or not using framegen at all.
DLSS Multi-Frame Generation Is Now Easier To Enable On Steam Deck, And It Makes Gameplay Worse - Steam Deck HQ
steamdeckhq.comA new plugin was released that can allow us to use DLSS Multi-Frame Generation in supported games on the Steam Deck, but it only makes gameplay worse.
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 it’s even a little bit worse.
VSync may complicate this though, depending on the method, since you may already be holding a frame for some amount of time, I hadn’t considered that. I personally use VRR, so it isn’t much on my setup.
