This feature allows input frames to be processed at a reduced resolution while generating output at the original resolution. For example, when playing at 1440p, setting the scale to 50% enables LSFG to generate 1440p output from a 720p input.

I have a 2560 x 1440 Pixels 165hz monitor.

I have lossless set to 3X and in my Nvidea panel set to 55fps

Your saying I should set it to 53 AND change the resolution scale in Lossless scaling to 50%

No, because you don't run 4k. You run 2k. So 1440p Is roughly 2K. Therefore set your render scale (the one below the frame gen option on the top left) to 75%. 

If you are running 165hz, it depends on the base frame rate you can achieve. Let's say you can achieve 50FPS most times, then lock your frames to 50 FPS using RTSS. This will mean if you use frame gen X3, you will achieve 150 frames per second, and give yourself 15 frames overhead. Or you could lock at 54FPS and the X3 would give you 162FPS, givng you only 3 FPS overhead. If I were you I would lock at 50. 

You didn't say if you had a G-Sync monitor or not.

yes G sync

Ok, so, also go in the Nvidia control panel, go to manage 3D settings and select Flight Simulator. Make sure V-Sync is OFF, and make sure low latency mode is selected.

Inside MSFS, make sure v-sync is also OFF. This will reduce your input lag.

Make sure it is also selected as OFF inside lossless scaling app. 

Make sure G-Sync is enabled. So, if you drop below 50FPS, G-Sync will take care of it, and by capping at 50FPS in RTSS, you'll smooth the frame pacing, and shouldn't ever go over your monitor's refresh rate of 165hz. 

PS for those without G-Sync monitors, you would probably need V-Sync on somewhere at the expense of slightly higher input lag, to avoid tearing. Another bonus of having G-Sync at higher frame rates with these frame-gen programs.

For example, when playing at 1440p, setting the scale to 50% enables LSFG to generate 1440p output from a 720p input. This provides a performance boost with only a minor quality trade-off (depending on the game). Note that this is not related to image scaling; rather, it reduces the amount of information available to LSFG for motion estimation.

So, that is why at 4K, it's best to set it to 50%, it will generate the frames at 1080p, which it was designed to do, and output them at 4K. 

That's why I never found this feature useful for me: I have a 3060Ti and a 1080p monitor. Unless I fly the Fenix, my GPU usage is rarely over 25% (with no FG); so I never needed to downscale.

This isn't downscaling the image. That's a separate option.  This refers to the fake frames it is generating. IE, running at 4K you can select 50% because then it will generate the extra frames at 1080p and then render them back out at 4K.  

For higher resolution use at higher than recommended framerates or use the "Resolution Scale" option to downscale input to 1080p:
For 1440p, set it to 75%.
For 4K, set it to 50%.

Note that this is not related to image scaling; rather, it reduces the amount of information available to LSFG for motion estimation.

Very interesting. I keep on thinking though what's the use of this app when you need (preferably) an fps of 40. If I can get a steady fps of 40... that would be great and good enough for me. I don't understand the need to get that up to 80 or 120 with a bit more lag as added bonus. Or are all people here in the camp of those that say 40 fps sucks and isn't good enough?

Last weekend, when I tested the lossless scaling app, I enabled the fps counter for once and noticed that in medium to heavy situations my fps is around 35 to 40. When things get really though (occasionally) it may drop to 25 or so. Now that's all fine with me. With the app that 30 was doubled to around 60 but things felt sluggish and laggy. I suppose I didn't use the correct settings (I might have used different settings knowing the recent information) but in short: MSFS2024 looked great without this app. I was hoping to be able to up a few more settings and still get a good performance but turning a few settings up obviously hurt my base fps and hence killed the app's performance.

Well, anyway, I think I still don't get what the use of this app is when you already have a good base performance...

Understood, Ian. Maybe because of the wrong reasons from my side, but I got your point.

Please remember LS was not developed for only flight simulators, but several other games. Also remember that, unlike these other games, we simmers used to be satisfied with getting just 30 FPS, while other users demand 60+ FPS to be happy.

You've seen one of the disadvantages of Frame Generation: in my sim the visuals are rendered at 120 FPS (so that they match my 120 Hz refresh rate), but the flight dynamics are processed at just 20-24-30 FPS depending on my settings. I find 20 FPS (and 6x FG) too sluggish for my liking and I have to do with 30 FPS/4x FG.

It isn't really good enough when using a high hz monitor with either

1.) Head tracking that polls at 120hz or 60hz, 40FPS would make it judder when looking around. Or fast panning. 

or

2.) A high hz monitor (say 120hz+) that has a VRR range of 44-120 (or 44-165 etc), it means G-Sync would never kick in. This app allows both to function in a fluid motion, which is very noticeable and nice to have. Plus it eliminates G-Sync flickering at lower FPS.

What hz is your monitor? did you lock your frames? Do you have G-Sync? there are lots of variables to take into consideration. You can't just X4 on 30FPS and expect miracles. There are far better ways to use the program than that. See my guide 🙂

Thanks for the extra information. The thing is I don't have judder when I look around with TrackIR. At least not that I notice LOL I suppose my smooth performance is also due to my native G-Sync monitor (ViewSonic Elite XG270QG). Afaik it has 30 fps as the lowest possible so I do think Gsync usually works on my PC. VRR might go even lower than 30, I'm not sure... And I never heard of G-sync flickering and have no idea what it is.

I think that looking into Lossless scaling is, at least for me, looking for a solution to a problem that I don't have. I was mainly looking into it to see if it would help for those rare circumstances where performance does drop low noticably and in the hope that I might be able to set a few settings higher. I guess it doesn't work that way.

Sounds like you have a hardware-based G-Sync monitor then, normally they go as low as 1FPS. They are really really good and much better than G-Sync compatible ones. 

 

P.S I just checked and your monitor is a hardware based true G-Sync monitor throughout its full VRR range. So in all fairness, Lossless scaling will probably offer you little if you are happy with 40FPS:-).

Ah, thanks for clearing that up for me! I knew I had a hardware-based G-Sync monitor and also already thought VRR would go as low as 1 fps but couldn't find the proper information so I didn't dare to say that with confidence. Glad you found the information! So now I understand why I didn't understand what everyone is so excited about, haha!

And yes, 40 fps is totally fine with me. Or ANY fps as long as it feels smooth. 😉 Okay, right, that was lossless scaling for me, back to flying!

Isnt LS supporting Gsync? At least there is an option for it selectable... Means even with a range of 48-144, like my G3223Q, Gsync perfectly works with FPS after LS amplification. As it does for native Frame Generation by nVIDIA?

Yes it is. And yes it will. But please see what I wrote previous regarding setting it up, because G-Sync alone wont smooth it out. 🙂
