I bet many of you have heard of a tool called “Lossless Scaling,” which claims to improve gaming experience by smoothing out the game through LSFG frame generation, optionally using various scaling algorithms and machine learning models (such as LS1) to improve quality or performance.
The description sounds great. And many flightsimmers on the Internet have reported excellent results by using the tool. Sadly, that wasn’t the case for me.
I’ve been using this tool for a while, probably around the time of its second update. Since then, I’ve enabled it on and off numerous times and played around with various settings, including loads of suggestions I’ve found online.
But the results have been similar every time:
1. It does improve clarity, but the entire screen looks a bit grainy compared to when it is not used.
2. After enabling this tool, my frame rate certainly drops (from 10 to 20).
3. And the most frustrating thing is that it causes artifacts and serious stutters that I don’t experience when I am not using the tool.
I dare not say the tool is a hype, as many people report great results with it. That’s why it took me so long to write about it here.
Perhaps I didn’t do it right ? Or maybe it’s simply not for me ?
Should we stay away from it ? Er…I don’t know.
Perhaps I should say I don’t object other people from trying it since the little tool costs just a few bugs.
Also, I didn’t see any harm from installing and uninstalling on my system.
Morevoer, your mileage could be very different, too. Good luck!

Hey, just thought I’d drop a quick message to say that I’ve recently actually started using LS again for flight sim and it can make a big difference to the overall smoothness and immersion of the sim.
I think the key things for me that have made it work well are:-
In nvcp:-
Disable gsync Set vsync to let application decide Set low latency to off
In monitor:- Set refresh rate to highest mode, for me, this is 240hz (this also reduced resolution from a ridiculous 7680×2160 to a more reasonable 5120×1440, and also removed gsync as an option in nvcp anyway). If gsync is still an option in nvcp, see if there’s an option to disable vrr in your monitor. Weirdly, on my monitor, I actually need vrr ON in order to set refresh rate of 240hz, but then vrr is actually disabled anyway.
In games/sim:- Turn vsync off Turn reflex off Turn frame gen off Set gpu based graphics as high as possible, set cpu based graphics as high as you dare (basically as low as you can stand without it looking lifeless or messy).
In lossless scaling:- Set frame gen to latest version 3.1 Set mode to adaptive Set target to your refresh rate (240 for me). Set flow scale to 50%
Set capture api to wgc (or use dxgi if wgc does not work, it depends on your windows version) Set queue to 1
Set scaling type to off
Set sync mode to default Set max frame latency to 3
Turn off hdr Turn off gsync
You get some artifacts over large bodies of water, but other than that it’s extremely smooth. I think key is to have as high a refresh rate as you can, a target to match it, and all types of sync disabled in games and in nvcp. Also low latency stuff all off. Only use the default sync in lossless scaling. Forces the sim to be gpu limited and it’s so smooth now.
If you do decide to give it another go, try this setup, it works really well for me now.
Cheers, Glenn

Hello Glenn,
Thanks very much for the details of LS that works on yours. I’ll follow your instruction and give it another try.
I do hope it works too. ;)
Best,
Tom
