I’ve seen a bunch of people recommend this and I’ve played around with it a bit since they initially added frame gen to Lossless Scaling. It never feels smooth. There’s always some stutter/jitter in the frames that makes it feel terrible, even when it’s “100+ fps”. Definitely feels worse than a native 60. Also worse than AMDs fluid motion frames option which does feel and look smoother. I leave it installed and come back from time to time to see if it’s improved but it’s just not something I’ve found to be enjoyable or an improvement to my gaming experience.

does anyone know whether this works on linux/proton?

This tool is great for people who play fullscreen games, but if you play windowed it currently won’t work properly for you (even in windowed mode).

I got it to try and bump my 1440p@60fps to 1440p@120fps without making the GPU want to take off via the frame generation, and unfortunately while it does have a windowed mode that either draws over your window (it’s wonky and slow) or a mode where it just does fullscreen but with black space to pad to your window size, which looks silly.

I like what it does but I have other stuff I want to see on my screen while playing so want to keep my games windowed.

I would also say if you are playing a game that supports dlss/FSR with frame generation, just use that instead as it will use frame buffer data to drive the upscaling/frame generation, which is pretty efficient and the data is already on the gpu. Lossless scaling is basically taking REALLY FAST screenshots of your game and upscaling/frame gen then drawing it over your screen quickly.

I love how hard everyone is trying to emulate frames instead of actually putting the effort into optimization and understanding the software and hardware you work with.
