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.

Looks like only LSFG works well, no matter of drivers, making low framerate content look better!
RIFE + LSFG = better (for me)

As better, because RIFE 24>72 looks good but framepacing issue still occurs (driver issue), LSFG 72 target, voila, buttery smooth! Magic!

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.

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?

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

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?!

Under high GPU load, 565.90 causing stutters, but was buttery smooth all the time with average loads, 590.26 have no stutters under high load at all!
Noticed how quick my monitor VRR switches and holds, not happens with 566+ drivers!

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!

No, 581.42 is the same as 29, different framepacing in different applications, which was the same for all applications for legacy 565.90 driver, 2 drivers before NVIDIA App transformation!

UPD: I will try dev drivers, 590.26 for test!

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!

I need someone to test this with different or same GPU - my friends with almost identical PCs have same issues with different drivers, thats not local issue!

UPD: Thats VRR problem, simple FIX is running LSFG ontop of RIFE interpolation with same FPS gives very smooth behavior, which means the driver interferes VRR framepacing!

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!

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!

Fair warning, I know just enough to be dangerous.  If any of my thoughts / ideas are wrong, let me know.  I have no belief I understand this topic particularly well. 

I have a projector in our media room, so I've been using a capture card, videoprocessor (a software application from videoprocessor.org), and madvr for hdr to sdr tonemapping.  I've been really happy with the results and was curious if SVP could help smooth out the frame rate.  I've seen references to... I think it was MPV video renderer maybe?  I believe there is some criticism that madvr may use a ton of extra processor that either doesn't yield significantly better results or better methods now exist to achieve that tone mapping. 

Essentially I'd like to know if I can use videoprocessor (which has a dropdown to select any directshow video renderer) and select... SVP maybe?  And then is there a way to tie in something like MPV in place of madvr to get smooth frames combined with great tone mapping?  I'd like to avoid having to change HDR (which I'm doing by mapping everything to sdr) and frame rate "bonks" on the projector as it takes 4 - 8 seconds to resync the HDMI signal.  I also use the black bar detection to zoom video to my cinemascope screen. 

Is there a way to do what I'm wanting to do?  Because I use videoprocessor, I've installed the SVP application, but I don't know where to go from there.  I don't see "SVP" in the video renderers, but I did notice... was it MPC Video Renderer show up?  Which I believe was installed alongside SVP. 

I apologize for these questions.  I have madvr setup and working well.  Just curious if there are some other options to maximize the viewing experience and potentially have buttery smooth frames for movies. 

Thank you for your help!

There's a few commands that do nothing at all which means they don't currently do any harm and I'm not going to repeat myself The rest is just personal choice. The shaders are fine, but these days I only use them for edge cases, because when watching in VR on a very large screen at short distance exposes issues with external shaders that you won't see on a TV or even on a projector. Aliasing is the most obvious but depending on the source, other issues can and usually do arise.

is this works for anyoone? i don't want to take any risks!
