As 4070 user, can clearly state 50 series lmao expensive thing, no need for LSFG? You cant do 4K X10 on 5090 yet!

Im talking about people who have very high refresh monitors like 360 Hertz or even greater! I will upgrade to 600Hz monitor soon!

So what do you do about the fast motion artifacts?

Nothing, just doing RIFE x3 + 240Hz target!

It turns out that there are two bottlenecks, not just the GPU because SVP also seems to have an upper processing limit. Even with my GPU running at 50%, I can't go above 80fps before the movement becomes choppy with 4K 3D movie files. LSFG takes me well above 80fps but SVP is smoother so using them both together, they compliment each other.

I finally got SVP working with LSFG 3.1 Fixed. 4K 3D input, SVP Rife (4.25-4.26 heavy) set to 60Hz and IC 6%.  For watching movies, anything above 60Hz shows no obvious difference, so sticking to 90-120Hz. But  I can easily do 240Hz even though flow scale is 100%. I just wish there was a Rife model with even less artifacts. Running IC at 4% reduces artifacts to the bare minimum but its choppy for slow pans so I'm using 6-8%.


Thanks telling us about LSFG smile

It basically brute forces SVP into working, so even running with IC at 8% is still smooth.  No need for LSFG, config files or anything else. Seen it with my own eyes. I'm sure LSFG helps with smoothness overall, but this just works.

It's a bit of a beast. With something like that you realize how much of the smoothness depends on the GPU.

You DIDNT changed CONFIGURATION FILE parameters, real timestamp tolerance to 1 plz, then try to generate, LSFG will ignore generated frames and will duplicate or generate stutter frames instead of generating! Actual GPU usage decreased, tried to use on 90% usage before LSFG ontop, hidden trick only adds extra 2% without drops!

If i set real_timestamp_tolerance to 1, it shows 24/1000 fps but panning scenes move choppy exactly like original 24 fps, meaning it moves like 1x with scaling effect ON.

Where is the black insertion setting and what does it do?
For performance increase, just change HDR support checkbox to OFF, that's the real memory hog.

After further tweaking, i think these settings actually improve smoothness, giving stable fps:

Thanks Ricky!

I'm upgrading soon. My aim is to try and get at least to 80fps with SVP although my hope is 120fps. If LFSG can help with that then that will be great. Those settings you posted does that include the config file changes mentioned previously? How smooth is the result? I gave up on LFSG because  of horrible fast motion artifacts so how were those?

About 3rd: when you want flatten the playback out of RIFE alone - make sure you edited framerate_tolerance to 1 and interplation multiplier to 1, which would trigger interesting things, better suited with black frame insertion, CRT shader, not implemented yet!

1. It does seem overall to be smoother than even Rife
2. I meant Rife/LSFG.
3. With multiplier set to one, I get massive judder with or without Rife so it's not a GPU thing.

OK. I've found the issue. Rife is smoother with MPV than MPC but GPU usage is a little heavier. VR pushes it over the top so there is no headroom. But it seems to work with LSFG for MPC.

3. Theres no judder with proper CONFIG .cfg parameters, you can make no interpolation looks better, LSFG has a lot of hidden tricks! Thats GPU and backend thing!
1. Ofcourse LSFG smoother, tested many times, smoothness is our priority!

Hidden trick: with proper .cfg parameters, for example, you want to trigger 2x LFC instead of monitor 3x LFC strategy, works!
Example: video container 24 fps > 2x interpolation w/real timestamp tolerance 1, with that hybrid I can actually activate black frame insertion thing!

I was just talking about performance. LFSG is smooth. But it has some artifacts that can't be fixed except maybe by making multiplier x1 which won't work with my GPU because I don't have enough headroom when using VR.

The end result is smooth without the Rife v4.25 vertical motion artifacts and only very occasional micro-stutters.

Has HAGS improved enough that you no longer recommend turning it off for RIFE?
What’s the current advice — keep it on unless it causes stutter, or disable it for smoother playback?

As @RickyAstle98 said, it depends on your setup. I get massive stutters but others users with similar setups have no issues.

From testing, my current setup (finally) gives me not more than 1% stuttering. More than that usually means it's time to reboot the router. I'm not 100% about this, but it's definitely less than 5%. Looks like we both happy but maybe it took me a lot more work lol.

Turning off MPO is better for slow pans, smoother overall, almost stutter free at 6% and pretty much stutter free at 8%. Since MPO is off I've also turned off the other Windows optimisations since Nvidia MPO is designed to work with them.

Never heard of Special K but it looks interesting. Some of what it does is kind of what I'm doing but with Windows 11.

BTW what do you do with the Sync intervals, disable it?

Update:I've been testing my new settings with fast action. But I just tested my new settings with slow panning shots and it forced me to make some changes to my original recommendations.

As of today my settings are SVP: Rife v4.25, IC 8%, Blend Adjacent Frames. MPV: Interpolation on, resample audio. GPU: 577 or 566.36. Windows 11 Optimization for Windowed Apps: MPV

Optical flow seems to also help possibly removing the need for the overclock but at the cost of the occasional major stutter so nope.

SVP doesn't work well with HAGS which means that Nvidia Smart Motion doesn't work properly. When it doesn't crash, it might work for a little then starts making everything stutter. Is there any chance of a fix for that so that Nvidia GPU owners can try Smart Motion paired with SVP?

Dunno. I read about it somewhere that flip gets similar performance to exclusive that's why I re-enabled Nvidia MPO, but if you turn on exclusive then it is smart enough to bypass itself or something like that.

The MPO doesnt work correctly with Windows 10 system, thats why LSFG only allows DXGI renderer, DWM>Composed Flip instead of FSE>Hardware Composed Flip (your behavior)

The SpecialK somehow solved all judder/jerks/stutter problems, continuously holds refresh rate much agressively, but unstable on seek, I dont want to lose performance/smoothness in games for video players, SpecialK helps, trying to inject SpecialK window management through mpv library!

UPD: MPV Interpolation argument yes and D3D11 sync intervals solved the problems, but unstable enough!

Never heard of Special K but it looks interesting. Some of what it does is kind of what I'm doing but with Windows 11.

BTW what do you do with the Sync intervals, disable it?

Update:I've been testing my new settings with fast action. But I just tested my new settings with slow panning shots and it forced me to make some changes to my original recommendations.

As of today my settings are SVP: Rife v4.25, IC 8%, Blend Adjacent Frames. MPV: Interpolation on, resample audio. Windows 11 Optimization for Windowed Apps: MPV

Optical flow seems to also help possibly removing the need for the overclock but at the cost of the occasional major stutter so nope.
Any Nvidia driver should be fine, but if you are having issues then fallback to either 566.36 and 577.

I think ignores because of this magic things, running LSFG at same target FPS as RIFE - making mpv looks smooth, very smooth, despite not generating frames at all!
Also I think LSFG ignores newest compositors because how quickly my monitor switches and holds refresh rate, currently at stable 581 (yes reverted back for games), during standard mpv playback without any interpolation, VRR fluctuating!

UPD: Running external video capture to get VRR jumps via SpecialK measurement, mpv during 1 minute scene at FIXED 24FPS fluctuates 210 times (no interpolation), and only 30 with LSFG ontop, DWM works flawlessly!

Cool. We can only use what works.  Since I'm using Exclusive Fullscreen it's probably bypassing Flip and using DWM anyway lol.

Wait, 590.26 FIXED some issues?!

I would be surprised if LFSG ignores filp models since modern Nvidia drivers all have Multiplane Overlay built in specifically to work with it. This was one of the Nvidia features I turned off not knowing that I was probably hurting more than helping.
I wouldn't play with the MPV swapchain. From my testing I found that the default is ideal so that's what my SVP Nvidia settings also use. I forgot to add this to my settings list because I set this up some time ago.
As for transcoding speed, I only look at the end results. Are packets dropped? Is the GPU stuck on 100%? Is SVP stable around 0.99 to 1.01 or is it fluctuating? My current answers are no, no and stable.

UPD: Some people said that dev driver 590.10 also better with competitive games, the quickest driver by latency, need to test with same parameters!

Thanks for the the heads up smile

Update: I watched a full 7 minute sequence with zero stutters and is surprisingly smooth, considering IC 6% but 8% is more reliably stutter free.

As of today my settings are SVP: Rife v4.25, IC 8%, Blend Adjacent Frames. MPV: Interpolation on, resample audio. GPU: 590.26, Smooth Motion (Globally) On. Windows 11: Optimizations for Windowed Games.

These SVP settings fixes Rife's double image issues with fast vertical motion in movies like Dr Strange 2. Also GPU usage is greatly reduced. Maybe this is because it doesn't try to interpolate as many frames?.
These MPV settings stops it from dropping frames and helps with any remaining smoothness issues after SVP interpolation. I also use exclusive full screen but for most users I don't think this is "needed".
These Nvidia settings are not the only option but these work as well as any. A mild overclock still works best which is strange considering the GPU usage but maybe the peaks are higher?
The Windows settings are for MPV and other relevant software to work optimally with Windows 11.

I'm sure there's other ways of doing this, but this is the first time I have an explainable reason for each setting instead of just hope. This works for my VR setup so YMMV.
