I've been experimenting with "Lossless Scaling" app - it actually works with video players too (especially MPV).
It's not exactly easy to use (unlike SVP), but the generated quality is similar to RIFE and with fraction of power - I can actually generate 6x24=144fps at 4K, which is mind-blowing!
Also, since it doesn't touch the video directly, I can even speedup the video (when movie is boring) and it doesn't affect performance.
But it's full of artifacts, even around subtitles, which sucks...
But still, quite impressive, there is definitely a huge room for improvement here at SVP smile.

Thank you gerappa, that fixed it for me!
I'm using new 24.12.1 driver and MPV player.
Although with my 7900XT I can do only 1080p (at least I can still use 2x speed when movie is boring).
Also, it's heating my room quite a lot, I forgot how power hungry this RIFE is. But the quality is so much better compared to CPU! Still, I can't believe that even 10 years old Samsung TV can do this with similar or better quality without breaking a sweat.

I wish GPU vendors would make it easier for devs here with some nice API to double frames efficiently (if even old games can use it, then why not video players?).

Did someone reported this issue to AMD?
It's unlikely they will fix it if they don't know about the problem.

Also this article:

Links a different reddit post with more info how to test it:

It would be nice to see the quality comparison.

With my RX 7900 XT I can do 3x framerate on 1080p, but I can't do 2x on 4K (using the default "Generic 4.4" model).
Maybe there is some slightly more efficient AI model I could use?

I have both disabled, but I had "Alter video frame size" set to "Resize to screen" and disabling this seems to help!
Thank you for such a fast response and easy fix!

I have the same problem with hang when I use seek.
It happens only with madVR. It happens almost every time I try to seek too fast - else if I wait like 5 seconds after first seek, it won't freeze.
Also it happens only when SVP is enabled. I've tried to change the "Reset on seek" option which affects the occurrence of this bug but if won't eliminate it.

I can't use EVR because it makes my whole system unstable - for example after watching one whole movie using EVR, my PC would not wake up from sleep or hibernation - I have no idea why (it took me forever to track that down!).

Yes there is probably bottleneck due to copying frames between GPU and system RAM (which is why the CPU and GPU usage is still low).

However I managed to make it work in madVR (with "Decrease to screen" option in SVP) by enabling "delay playback start until render queue is full" and "delay playback start after seeking, too" in the "rendering" / "general settings".

Now I can see no dropped frames and the upload and render queue are both full (in the madVR debug OSD).

Thank you for your assistance smile

Thank you for the info - I've managed to make it work if I use EVR CP and I use the "Decrease to screen" option (alter video frame size) which will downscale it to 1440p.

I was using madVR but even with downscale is won't work... There is some bottleneck somewhere. I will try to tweak the madVR.

I'm using 64 bit MPC, is there anything else I can do?
I will try to reinstall everything, maybe it will help.

Hello,

So is 4K supported by SVP using MPC player?
I have Ryzen 7 with 16 threads and RX 480 GPU so there should be enough power to handle it.
However there is visible video shuttering with big delay after the audio (while both CPU an GPU stays below 40%).

FullHD is working fine, only 4K (h265) has these problems.
I tried lowering quality but it doesn't help.
Playing video without SVP works fine, but I can't watch 24fps videos anymore smile
