What other settings are there that have can reduce GPU load without affecting quality? I will try those.

Type: 3.1 (better overall) / Fixed x2 / Adaptive refresh
Flow scale: for 4K you can use lowest possible 25% without performance mode
Capture: WGC recommended for Win11 users, try both, WGC provides less latency!
Queue target: ofcourse 2 (cuz we already at peaks)
Sync mode: Vsync
Max frame latency: 15
GSync support: supposed to be off (when you targeting refresh)

Type: Tried all the types. Fixed refresh isn't possible, only Adaptive.
Flow scale: I tried 25% as well as 50%
Capture: Tried this just now.
Sync mode: I use Vsync. Tried without just in case.
Gsync is off and all Nvidia gsync settings have been disabled on my machine.
I also cropped about 40% of the screen assuming 20 at the top and bottom does that.

None of the above made any difference. I'm using too much GPU. V2 models no longer make any real difference for me. I recently noticed a difference in quality between v1 and v2 models which is why I went back to v1. I never noticed it before, but my viewing equipment is much better with 4k per eye resolution and better overall clarity.

Using 3D, 100% GPU spikes but mostly around 90% so

Depends on settings, just drop your settings screenshot, will try to bring usable parameters, LSFG doesnt work better at peaks, cant discard frames just-in-time, unload frames in-time!

Thanks for the offer, but I don't have any settings because tried everything except anything that said quality drop like performance mode. 3.1 is a no/no. 2.1 with x2 works. 1.1 I think works worse than 2.1. Flow scale set to 50% and scaling scaling off.

Where do you get it from? Steam purchase?

Yes, Steam purchase, 1.5$ on sale, but you can use LS program w/o Steam!

UPD: Tested on 8 different PC and 3 operation systems, LS behavior always the same, magic works!

Thanks for the try out My 4080 drops too many frame when I try to run this and Rife v4.25 with 4K 3D unless I use LSFG 2.1 x2 scale. Even at 1440p in the lower quality adaptive mode too many frames get dropped when running LSFG 3.1. Maybe Performance mode would work but there's no point if I'm going to loose the laser projector like quality I have. Interesting software though.

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.

The sync intervals prevents NVIDIA default driver compositor deliver frames non-directly, monitor VRR in charge, but breaks at seek again!
As I said, this is just VRR framepacing issue through the driver level, older drivers or LSFG ontop prevents monitor spontaneous refreshes, as you can see, earlier, I noticed how much VRR jumps got through standard MPV playback on new stable drivers, which not happens with LSFG ontop or after SpecialK injection, SpecialK makes 72FPS content not only smooth, but fast, not sure how that effect occurs, tested Gemini movie at real 60FPS compared to 24>60 and was surprised how SpecialK deliver frames, but I dont know how to inject SpecialK through MPV swapchain directly!

UPD: Found best solution to change present methods through NVPI program (inspector)! WORKS!!!

Did some more testing. My Nvidia MPO on Windows 11 works well, especially for fast motion, but I was having issues with slow panning. 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. More testing to do but, Optical Flow is helping smoothness again but without the stutters or at least that is the case so far. I'm basically back to where I was at the start lol.

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

Nope, doesnt happen to me, Exclusive Fullscreen behavior the same as before, destroyed framepacing with/without, thats your Win11 feature, my Win10 cant bypass that maybe?

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.

Thanks for the the heads up

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.

I will try to play with mpv swapchain parameters, LSFG ignores newest drivers flip models, producing smoothest image through DWM compositor, why not to force mpv to choose DWM composition too? Because before 566.14 driver, DWM was default!

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.

That maybe because it's using "smooth motion generation". I got a hacked version of that technology kind of working with my 40 series card, but it will be great to see it in action properly working. Thanks!

It doesnt, disabled!

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!

Strange because 566.36 always worked well for me. 577.00 was maybe even better and the latest official Nvidia release is as good as the others. So as I said it will be a local setup issue. Doesn't mean that "you" are doing anything wrong. It just means that there's something in your setup that is the real cause. Could be a card limitation or needing a "clean install" not an express install. Could be Windows 10/11 settings. For me it was kind of all of the above plus more because I'm using VR.

The dev driver 590.26 breaks framepacing in games now, MPV looks insane, even better than 565.90 legacy now! Unstable, one game already crashed twice!

"MPV looks insane" Explain?

Told you lol. Most of the driver issues are either game specific or as you have found out, they are local setup issues.  BTW I'm now using the latest 58x driver with no issues. So it looks like in my case it was mostly local setup issues.

But how different drivers breaks framepacing in different applications? I mean, for me 581.29 driver is most stable, in games, but breaks youtube, any video player, MPV, etc!
Thats why I asked for different GPU people test my issue!

That's why I said "most driver issues are game specific". But I am using 581.42 with no issues so not sure what is happening there unless .29 has specific issues. I'm watching full 4k (3840x2160) 3D movies and running a remote desktop at the same time with my GPU regularly dipping well below 100% and no stutters so far.

Mega Question about NVIDIA drivers / media player VSync behaviors

Stutters/jerks through any players after 581.X driver updates

Who can CONFIRM that any driver after 565.90 provides same/better smoothness levels?

As 4070 user, tested a lot different drivers, only 565.90 works flawlessly with any models, except 4.10ths and 4.25+

MPV behavior: 565.90 driver works flawless and perfectly smooth at any multiplier, w/wo interpolation, 566.36+ any drivers provides jerks!

UPD: Always running 565.90 driver before September driver release, changing TRT libraries do nothing! Any NVIDIA tricks like Fast Sync and others doesnt work, looks like new driver just breaks framepacing windowed modes at all, exclusive fullscreen works bad!

If you are having issues with 566 and but are OK with 565 then that might be a local issue. 566.36 is probably the most well known stutter free driver across the Internet. I'm using a 570 driver and it's as least as good as 566.36 and I'm probably going to try later drivers now that I've sorted the stutter causing issues. I had local wifi and bluetooth issues. But I also recently found out that Windows 11 works differently to Windows 10 and "optimizing" it can make things worse.  I caused  much of the stuttering by turning off certain Windows CPU security features and hidden Nvidia features the GPU needs to work properly with Windows 11. Turning them back on helped to get rid of the stutters.

Hello everyone,

I'm using Rife v25v2 TensorRt with scene change SVP Motion vector

I'm looking at the advanced settings of the software, all settings, it's been 3 months that I test several settings in a manual way directly, the options in the basic UI are really not sufficient, with the image comparison method I find that the image jerks despite having tested 50 different values.

So I wanted to know about the SVP motion vector method  in the all parameters tab, what are the best values to set to avoid artifacts between scene changes?

It's a pity there's no Discord because chatting on the forum is really hell for this kind of question.

and please don't tell me that the values in the drop-down menu directly in the profile are enough, because by exploring several softwares that don't work in real time there are so many options that you can modify with Rife and also use more efficient scene change methods, or use CVPR2023- A Dynamic Multi-Scale Voxel Flow Network for Video Prediction, or GIMM/GMFSS or MultiPassDedup
