Why are you limiting your 20s frame rates? My frames vary from 14 to 45 and LSFG handles the changing frame rates without issue.

That is the recommended setting in order to benefit from the x2 or x3 acceleration the app provides for a 60Hz display.

My fps are locked at 60. No variation.

Reading these comments, I think the big problem is that the frame counter of Lossless shows 60 but the actual RTSS or in game counter shows only the original FPS i.e. 28 or so. (Also on Rogen's demo video).

If there are extra frames being generated, why are they not shown in the RTSS and in game displays? 

How can we tell if there really are those extra frames.

The thing to understand is a window overlay is what Lossless Scaling projects and it's the overlay that runs at the frame generated rate i.e. 60 fps.

Think of it as projecting the sim display window to another window at a higher frame rate as a layer on top of the sim display window.

The sim itself will not run any faster (fps) than what you've locked the sim to run at, other programs don't see the overlay and hence don't display fps info regarding the overlay.

Essentually...

• You run your sim internally as unlimited.
• Then lock externaly at 20 fps (via RTSS or the use of the NVidia control panel/NVidia Inspector).
• Then use the 3x Lossless Scaling option to run the LS overlay at 60 fps.
• Which will vsync with a 60 Hz monitor screen mode (provided vsync is enabled in Lossless Scaling and you've chosen a 60 Hz screen mode for your sim).
• Result is really smooth vsync'd flying @ 60 fps.

On my demo vid the change from 20 fps to the 60 fps frame generated overlay should be easily visible, that's why I chose to demo at 20 fps to make the change to 60 fps more obvious to viewers. Yes the sim still runs at 20 fps as shown in the botton RH corner, but the LS overlay is running at 60 fps as shown in the top LH corner, the overlay then vsyncs to the screen mode Hz for a smooth flying experience.

As the screen modes I user are 60 Hz I need to lock the sim at 20 fps in order to use the LS 3x option, which brings the overlay to 60 fps, thus matching the 60 Hz monitor mode and thus vsyncing for smoothness. Likewise I can lock the sim at 30 fps and use the LS 2x option to bring the overlay to 60 fps, again matching the monitor screen mode 60 Hz for vsync.

It's really all about locking the sim at a frame rate the sim can maintain (i.e. 20 or 30 fps) and applying the correct LS multiplier to bring the overlay frame rate up to match the monitor Hz rate. I could also lock the sim to 15 fps, use the LS 2x multiplier and the LS VSync half option to achieve a smooth 30 fps vsync'd at half of 60 Hz, there are many options to suit almost any user's screen mode.

My suggestion is, if your unable to get it functional (if you choose to re-install that is), is that you post your various settings clearly identifying what is what.

Easy. Watch road traffic. At 30fps you can see their movements are noticeable jerky. At 60 they’re smooth.

Thanks, that explains it very well.  The only thing I am concerned about is that Rogen's video had huge slow passages where the sim was stuttering horribly and was far from smooth. Was that just the video? (I downloaded it to keep a copy and watched that copy, not the original).

Hello everyone,

Thanks  Rogen for your explanation on how this works. I like your analogy of having the source display being projected on another screen with the frame generation.

Anyway as per Ray's answer yesterday regarding NCP not working well with the app, I did install RTSS this morning and limited the FPS to 20 in it and I was able to make the app works by finally having 20/60 FPS. However I noticed some artifacts and sometimes stuttering while flying, nothing very bad but noticeable none the less. Some part of the flying were very smooth.

Weighing on things regarding my system and how happy I am with my P3D internal FPS like in EGLL with almost everything maxed out and using high texture resolution with PMDG planes, I prefer keeping on using my present settings and not adding the losseless scaling app for now.

You do surprise me. Yes, there are some artefacts when panning and some minor stutters when fps drops briefly below 60 but for me the advantages far outweigh these disadvantages.

Having 220 Ai at Heathrow compared to 160 previously plus the smoothness of road traffic and airport vehicles makes it indispensable for me. Each to their own of course.

I am keen to try this program - but does it mean I won't be able to use my second monitor for charts etc.?

Ray, this has probably been asked already in the thread and answered too, but I'm so busy these days that I couldn't resist asking directly 🙂

A am thoroughly missing FSHUD with P3D, and am divided between buying, again, a 1 month P3Dv5 Pro license or use P3d v6. Problem with v6 is not being able to use my preferred Airbus simulation - FSLabs 😕 - so, I might opt for a 5.4 install...

Having read about Loosless I thought I could probably try that too. My CPU and GPU are in my signature, monitor is 60Hz , 0,5 Ms... and I always use P3D at 30 FPS, either fixing it from the sim menu or using Nvidia Inspector, but I thought a good alternative might be to set it at max 20 FPS in the sim settings, and then use a x3 factor in Lossless to get a end result of 60 FPS?

Could you share a screen with your Lossless settings please?

Thanks

@jcomm, I can but it’s likely to be tomorrow as the weather here is too nice to be stuck in front of a computer.

v6 isn’t that popular as many developers have moved to MSFS. I can recommend v5 as all your aircraft will continue to work.

I used to think a 30Hz monitor with VSync enabled was the bee’s knees but this inexpensive utility changes all the rules.

@VHOJT, unless the second monitor is assigned to P3D display Lossless Generation is unlikely to work. If you have a modest spare PC or laptop you could use that for maps etc using WideFS.

You can  use a second monitor. Just tick the correct option in the setup.  The only problem is you have to "focus" on each monitor before you can use it. Makes it a bit of a pain.

And here's a pic showing the actual lossless scaling overlay (the smaller window) overlaying the main P3D window, this is the result of a monitor screen mode change and is prior to re-inititlaising frame generation.

That seems to be more an issue of your own, for myself (I have three monitors) I just move the mouse cursor over to the target montor and use the app I want, no big deal.

e.g. I have Little Nav Map and Active Sky, FireFox as well as other various applications open and in use during flight.

Occasionally P3D looses focus and I use the Windows key to bring focus back but it did that prior to use of Lossless Scaling anyway.

Cheers

P.S. I noticed I've got Microsoft's Focus Assist disabled, perhaps take a look in that area ?

Yes. It is off, but some of the sub-items were on. So I have turned them off as well. 

Will try again next week. (But I still think the program is unfriendly!).
