In response to my frustrations with Lossless Scaling, my friend Glenn kindly shared his experience and settings in the comment section of my post #903, encouraging me to give his setup a try since it is working pretty well for him.

Frankly, I really wanted Lossless Scaling to work on my system, too.  So I followed Glenn’s instructions (edited slightly for readability) below:

Glenn:  In nvcp (NVIDIA Control Panel):- Disable gsync; Set vsync to let application decide; and Set low latency to off.

T:  I don’t see the gsync function, probably my GTX3080Ti card doesn’t support it. Have reset low latency from Ultra to OFF.

Glenn:  In monitor:- Set refresh rate to its highest (for me is 240hz); this also reduced my resolution from a ridiculous 7680×2160 to a more reasonable 5120×1440; also removed gsync as an option in nvcp anyway.

T:  I am already using the highest refresh rate of 144hz on my 34-inch Mi Monitor; screen resolution used is the default 3440 x 1440.

Glenn:  If gsync is still an option in nvcp, see if there’s an option to disable vrr (variable refresh rate) 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.

T:  My monitor doesn’t support variable refresh rate.

Glenn:  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).

T:  All set as instructed.

Glenn:  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%

T:  All set

Glenn:  Set capture api to wgc (or use dxgi if wgc does not work, it depends on your windows version); Set queue to 1

T:  All set

Glenn:  Set scaling type to off; Set sync mode to default; Set max frame latency to 3; Turn off hdr; Turn off gsync

T:  All set

Glenn:  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.

The result:  Glenn’s recommendation does restore my scenery back to normal without unnatural graininess now.  However, while the artifacts and stuttering have improved, they are still severe enough for me to accept, not to mention the 10 to 20 fps drop overall.

I gave Lossless Scaling another try.  Sadly, it is still not for me.

In fact, the AMD FSR 3 Frame Generation in MSFS2024 seems taking similar approaches to Lossless Scaling.   Yet it is a lot more simple to use and produces noticeable results instantly.

All in all, our mileage is different, and Glenn’s suggestions should still be useful to others.

Thank you very much, Glenn.
