So the new 26 Heavy is better than the old 26 Large and is the best RIFE released. It fixes some artifacts cleanly like:
Alita Battle Angel 1:33:26

It improves the Occlusion issues at:
Alita Battle Angle: 1:34:50

But it still struggles with fast vertical motion. The artifacts shown below can be reduced but not fixed by using Image Comparison at 6% just like previous RIFE 25/26 versions. A 4080 can handle this so maybe a 5070ti can too. The last two examples are bad and look very ugly:
Alita Battle Angel 1:34:57
Amazing Spiderman 1:52:49
Man of Steel 1:46:37

I can get almost identical smoothness and less artifacts by using just SVP. With the exception of the PEL override for Quarter Pixel accuracy, the settings I use are a modification of SVP Automatic with the Quality Slider fully moved to the right.  Below are the baseline settings that work well. You can modify them depending on your GPU, but beyond a certain point up or down you may make things worse again so YMMV. 

Edit: Motion Vector Grid 24px works best for the Man of Steel artifacts at the above-mentioned timestamp.

With the scenes I using to test with, I can run 120fps with almost no artifacts. If Rife 27 comes along with even less artifacts then I might switch back to it because the motion is a little smoother and a little clearer. But not by much.

OK the artifacts issue is just one movie.  I can get 120 natively but  with LSFG  I suppose I can only get 120 by running SVP at 60 with 2 multiplier.

Try adaptive mode target.

The artifacts are being caused by the interstitial fake frames. Adaptive mode creates more a lot more fake frames. Can't see that helping. For whatever reason, the fast motion scenes in Alita are a mess with LSFG even if using with SVP.

guys, this topic is about RIFE, not lsfg

Or just put download link to 0.40.0-290 please?

Update in SVP gives me 0.40.0-291

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.

Its always system dependant, on my machine, SVP (RIFE) works better than friends beast setup, different drivers can make huge difference, especially on high end machines.
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?

BTW I've just seen someone running SVP with my settings. The RTX 4080 runs at around 100% on my machine. The 5090 runs the same settings at 38%!!!

Just seen someone running SVP exactly my settings (5 days ago / LSFG ontop)
RTX 4070 OC peaks 88% GPU usage @ 1.100V (72C)
RTX 5090 peaks 35% GPU usage @ 0.960V (55C)

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 should mention that I'm using VR which means I have less GPU headroom then you do. But FWIW, after more testing I've found an IC 6% setup that works with slow pans and fast action and doesn't stutter in between. There are a few decent Nvidia drivers but 366.36 is still the most stutter free. I've re-enabled MPO and using Windows Optimizations with MPV. Before I was able to run Exclusive-fs without Optimizations and I may return to that, but this also works. I've always run MPV without hwdec, but for IC 6%, hwdec seems to be better. Interpolation is running also. Finally for VR, regular rebooting of the router is absolutely necessary otherwise random stutters will happen because of the wifi connection between the headset and router.

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

Stutter-free: 565.90 driver (threshold 15%)
External capture: 72 fps (to count every single VRR jitter/stutters)

Rule: everything less than 8% of movie duration can be considered as stutter-free!

Capture results: 5.8% of stutters (high GPU load)
Capture results: 4.0% of stutters (medium GPU load)

Capture results: 4.5% of stutters (RIFE x3 + LSFG x1)
Capture results: 3.5% of stutters (RIFE x3 + LSFG x1)

LSFG was on sale so I bought a copy. I was able to get very smooth motion with 3.1 4x multiplier and 2.7 x2 or x4 (can't remember). Used by itself there is almost no hit on the GPU but the artifacts are obvious and pretty horrible. With SVP I was finally able to get them working together. But, LSFG has horrible artifacts for fast motion which ever way you use it which is a shame because otherwise it would be great.

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.

Then thats GPU issue, too high peaks, need some headroom to make LSFG work with!

UPD: I dont understand people with Windows 11 and 4K monitors, that trying to make 4K at newest models!
For me, RIFE x2 (FullHD) + LSFG refresh target, enough, better than RIFE x3 and also smoother, double effect!
