also, try to OC your RAM !!
I have i7 8700k @ 4,7 GHz and wasn't able to play 4K hdr 60 fps, until I OC my RAM to 3200Mhz (!) (just enabled XMP in BIOS)
People have here stronger CPUs like Ryzen 5900x and claimed the same thing- OC your RAM speed
I think the info about RAM speed should be sticked somewhere on the site, maybe? I've always thought that need fast and multicore CPU to achive playback of 4K hdr at 60 fps- that is ofcourse true, but didn't realized about RAM thing...
I have some random video glitches like a few repeated frames during playback, but when using only software decoder I get smooth video. I think I had this with mpv and with mpchc.
for 4k 10bit high FPS you need either RTX or fast ram. I had problems until I OC my RAM to 3800. I have 5900x
Hi there!
Could you please refere to Blackfyre topic?

Can 5900x handle Vector Precision at HALF Pixel and Vector Grid at 4px ???

Why do you think so? I can't confirm.
Well, after setting 23Hz in NV control panel, then look at Ctrl+J Madvr stats and you'll see ".. one frame drop/repeat every 1,06 hour..." (the same when setting 59,940) and I can really noticed that.... With intel igpu-8700k in my case, Madvr stats show "...frame drop every 7 hours..." or more.
Maybe I'll take a risk and buy new CPU and motherboard...
Hello!
Because Nvidia is not able to keep their audio/video clocks at stable 23,976 fps, I' m planning to move to intel side. On Intel's hardware, I get stable 23,976 fps (also with 59,940) without any frames drops.... So, is new Intel iGPU with 11 gen. CPUs-like 11700k, could handle interpolation with 60 fps? They say it's equal to GTX 1030...?
...sorry, double post...
> What kind of CPU is needed for 4k30 to 4K120
8-core Ryzen is good even w/o NVOF
Does Ryzen CPUs support software decoding of 4K 10 bit hevc?? I cannot find this anywhere. Everyone writes that only models with APU but I need to know ie 3900/ 5900 can do it? I’m trying to avoid to do hardware decoding, especially when using with SVP Pro. It might be too much for GPU, I think...
Hi,
Sorry for offtopic but could you refere to this topic: https://www.svp-team.com/forum/viewtopic.php?id=6081, because of the hardware that you have. Is your 3900x able to handle these settings what Blackfyre asked for?
Well, I think we might need more cores ... 12 or 16 from AMD. Personally I would go with 3950x / 5950x... Now, my 8700k @ 4.7 GHz (multicore enhacment enable) is reaching 90-100% usage when watching Aquamn 4K HDR with 59,940 fps. That's my settings:
you can check this topic here:
Did u change monitor/tv hz to match that ? eg 71.928 for 3x
I've just try to set 3x, but refresh rate only can set @ 59,940 Hz with my Samsung TV. Got keeping grow frame drop number but it seems also smooth...
Why would you use svp when new tv's can do interpolation better ?
Yeah, maybe you're right but in my case I have some choppy playback-single moments, with my Samsung's inerpolatiion, it's quite old model: KU 6400.... Or it might be because of nvidia eternal problem with keeping 23,976 clocks in perfect sync? Anyway, with my config above, I didn't found any artefacts around the moving objects etc.
I've decided to share my SVP Pro and MPV Player settings. I think I've achived some "normal" playback smoothness (without soap-opera effect). Maybe others will be interesting to do this too. I've spent a lot of time reading/asking members/devs about diffenrent things.So let's go...:
Audio/Video configuration:
PC-->A/V receiver-->TV
Windows settings:
In NV panel:4K, 59.940 Hz, 12 bit, 422 colour format.
In Windows 10 display properties: Enable HDR
Hardware:
CPU: i7 8700k ( with MCE enabled--> 4,7Ghz)
RAM:32 GB @ 3200Mhz
GPU: RTX 2070 Super (GTX 1070 was using before-also fine,just replaced because I needed USB-C video otput)
MPV config file:
vo=gpu
profile=gpu-hq
gpu-api=d3d11
hwdec=no (in my case I had some choppy moments when using hardware decoding, I think it's due to GPU overload)
video-sync=display-desync (I think it works like Reclock but lets you do bitstreaming without audio drops)
volume-max=100
hdr-compute-peak=yes
volume-max=100
ao=wasapi
audio-exclusive=yes
audio-spdif=ac3,eac3,dts-hd,truehd (it lets all multichannel audio to passtrough)
I do not use NVOF function, don't like, it has worse artefact masking in my opinion.
Above settings I use for watching 4K HDR and 1080p; with 23,976 fps content.
AND- don't forget to turn off TV's interplation feature, it will ruine whole SVP effort 
SVP Pro settings:
SVP does transcoding via mpv player which is unable to preserve HDR meta-data after encoding...
Will this be ever possible? Maybe with in the last HDR-able update of avisynth, if not from mpv engine?
Nope. The "avisynth filter" author can't replicate the crash on his rig... and it actually ReClock who crashes, so .... dunno what we could do about it.
> One more thing when do all files modification about adding 10 bit support with DirectShow, MPV player do not playback in 10 bit mode then (?!)
are you sure?
mpv must work the same way it used to.
Now, mpv does work in 10 bit mode, after update
... just want to add one thing about Reclock crushing- noticed that it does work with 1080p movies but crashing with with 4K HDR. Is this can be some hint fory you,maybe?
>
If you open the AviSynth Filter properties, the "AviSynth script to load" field must be empty. Is it?
yeah- it's empty, still crushing tho....any ideas?
Well, with 64 bit MPC-HC+madVR it's OK, ofcourse madVR stats are showing some reapted frames but I personally didn't noticed that
Oh! One more thing when do all files modification about adding 10 bit support with DirectShow, MPV player do not playback in 10 bit mode then (?!)
Is this going to work with 32 bit MPC-HC?
Asking because I wanted to combined SVP Pro with Reclock to get perfect audio/video synchronization
I've tried to do it but got crash:
9900k
rtx-2080
32gb ram
win 10
potplayer
madvr
svp pro 41080p60 cpu:15% gpu:45%
2160p60 cpu:22% gpu:77%would like to use less gpu for svp.
gpu for madvr. cpu for svp.have sellected "no acceleration" for gpu but no change.
svp works beautifully. I love it.
are you able to play smooth 4K HDR at 60 FPS with MPV player, using only CPU? What's the CPU's load and clocks then?
are you sure of that there are no single drop during watching a whole movie? Some time I was thinkig the same but after watching after some 20 min, suddenly noticed single drop frame on TV with its interpolation...
and your cpu might be to weak to handle a 120fps interpolation with 4K, hdr content
Hello all
I've been using SVP and MPV together for 4K HDR @48FPS movies for a long time.
Are you able to play 4K in 10 bit mode, with 59.940 FPS, without HW decoding- in mpv-with your 8700k CPU?
2160p60 cpu:22% gpu:77%
Can I ask you how’s your PC efficiency when playing 4K with 59.940 fps, 10 bit output and without any of the HW decoding via mpv player?
thank you, i will stay with 60fps.
does with 4K, 59.940 fps and 10 bit output run smooth for you, then?
thanks @Blackfyre for reply!
First of all I want to stay with bitstreaming the truehd signals so methods like Reclock is not for me
Well, finally I upgrade my laptop CPU from 6700k to 8700k and I'm able to achive a watchable standard with 24x2 and settings like here (also using throttleStop to keep CPU alive in hard-laptop enviroment ) I mean 4K ,10 bit content, ofcourse !
I thought about i9 9900k but for a laptop it's too much throttle, with 8700k I can barerly keep avg 4.5 Ghz..

currently my display is set at 59hz and i have svp set to 2.5, so for 23.9 movies i'm getting 59.8, is there a better setting i should be using?
24 x 2, 24 * 3, etc
if I choose option with 24x2 , what refresh rate I should go with: 50 Hz or 59 Hz in Nvidia Panel?
