Yes, what's inside the configuration file, which is located in this folder:

C:\Users\YourUserNameHere\AppData\Roaming\mpv

I have a 4790K @ 4.6Ghz
MSI 1070 Gaming X
16GB 2400Mhz (dual channel 2x8GB).

I run 4K SDR at 60FPS smoothly, and 4K HDR at 50FPS smoothly without a single frame drop or frame delay. So really, it should be SUPER easy for your setup to do it, just as you ran it fine before.

Use to screen framerate instead of 2X for SVP. When you want to watch content at 2x, go to nVidia control panel and change the TV/Monitor to 50Hz. But given your setup, you should be able to run everything at 60FPS, including 4K HDR.

Here is my mpv.conf below:

I removed the Shaders and audio configuration from the code above, but unless you're watching on a big TV, you don't need them.

If you do not have a mpv.conf file. Create a mpv.txt file in notepad, copy and paste the codes above inside it, save it, and then change .txt to .conf and place in the MPV folder I noted in the beginning of this post. Not the MPV directory where the .exe is, but the one where the configuration goes.

For my SVP settings, here they are below:

This is not normal behaviour.

Download Malwarebytes Antimalware, use trial. Do a FULL SCAN of your entire system. If there's a USB that you use to reinstall programs that you have on it after you format, or any external hard drives. Plug them all in and make sure you do a custom scan on them too.

There is no way installing Windows and after a while you get slow downs, and then you have to format and install Windows again. This is not a way to fix issues. You need to figure out the software, or the tweaks, or something that either you're doing or being done to your system that is causing your issue.

No way, that's too many artifacts. No I do not get anywhere near that. Maybe in a few scenes in a movie, I get a few artifacts, but nowhere near this bad where you can't even tell what you're looking at from how many artifacts there are all over the place, and majority of the movies I don't even notice any artifacts. Are you sure you have the PAID version and everything updated?

What media player are you using?

~$300 in Australia, haha! Electronics are all very expensive in Australia.

I don't know about nVidia Optical Flow, I'm sure someone will help you there. But regarding the negative things you heard, don't bother listening to them. After getting used to watching my TV shows & movies with SVP, I have never gone back. I cannot go back. Also right now, it's on 50% discount and it isn't really expensive. Just buy it and try it. Read around the forum here for issues you run into, try different settings, etc and then if you run into things you need help for, just ask on the forum and surely someone will assist you.

As for artifacts, yes they will always be there. With the right settings you can minimise them to occur rarely, but honestly overall smoothness increase outweighs those instances where I see artifacts. At least with my settings anyway.

My settings aren't the smoothest, but I try to minimise the artifacts as much as I can.

By the way, SVP is a mostly CPU intensive program. GPU helps a little with SVP, but it's mostly used for upscaling and the media player.

You have to find the balance that satisfies you in the settings. The smoother you want it, the more artifacts will occur, to reduce artifacts, you need to slightly reduce smoothness. I provided my settings for 1080p for you because that's what I use to reduce artifacts and have decent smoothness. But you cannot have a perfect combination of both perfectly smooth and zero artifacts. The only way that is possible is for example if you consider 60FPS smooth, then for the video or movie itself to be shot at 60FPS, being watched at 60FPS. Motion interpolation will naturally introduce artifacts. Some very high end TV's and higher-midrange TV's too can do motion interpolation while keeping the artifacts to a minimum, they have built in chips dedicated to doing it, and teams of engineers and software programs dedicated to perfecting it year after year.

SVP is the cheaper method available for those who don't have those expensive TV's.

Having said that artifacts are a lot less when I am watching 4K content on a 4K TV. The lower the resolution the more artifacts I notice when I use SVP. But there is no perfect solution. The movie industry has it in their heads that 24 frames is perfect for movies. A bunch of old timers, who grew up in an era & generation that had that limit, but the limit was the highest standard at the time. The problem is the majority of the population is already used to 24FPS movies, and movie makers are used to it and love it too. It is the standard. The soap-opera effect as they call it is something they despise, because it's very hard to change ingrained perceptions that have now crossed generations.

Try these settings for SVP:

Right click SVP, under application settings, make sure your GPU is selected for GPU Acceleration.

Right click SVP, under outer lighting, click DISABLED.

Right click SVP, under video frame, untick "detect and cut off black bars".

Right click SVP, open file via MPV.. and see if you like these settings.

You're not giving any details as to what media player you're using or what content you're watching, if it's in 1080p or 4K, or HDR? What TV are you using?

But don't worry in your case if you get one of those listed TV's above that are high-end TV's. You will notice the difference. My TV's maximum brightness is 400 Nits, so even when HDR works the difference wouldn't be as noticeable. The panel itself is decent, but nowhere near the TV's you listed above.

If you right click SVP the maximum threads in the options is 21, however if you go on additional options, then click ALL Settings. You can scroll down and change "threads" to however many you want manually. But I am not sure if there is an actual limit on the back-end of operations. Wait for Chainik to answer that question.

Also possible that it hasn't been tested beyond a certain amount of threads, so the answer is unknown. For example if the maximum they have tested is on a 24 core (48 thread) processor and it works fine and utilises all, but if you go beyond that, it's unknown territory and it should theoretically work, but who knows? Maybe not. I am just guessing here. The option however to change thread count to any number you want is available in All Settings.

Thanks, I am testing new settings with DX11. Safe to say though that even with vulkan, do not use "video-latency-hacks=yes" from the above list I posted. I was testing it for a short time, massive frame drops with upscaled content, for example 1080p to 4K. I try to read through mpv changelogs every time a new version is released and see what new changes are made and what new options that have been added to add to my personal settings. Every few months I post my settings here.

Based on my testing yesterday, I still prefer on my TV to use vulkan for watching 4K HDR content (even though it's being converted to SDR, the colour retention and highlight details in high contrast areas seems to be done better with vulkan conversion, than with my TV processing HDR content, if I had an OLED screen or a high end QLED TV, then yeah colour reproduction & contrast will be done brilliantly on the TV side). But with the mid-range TV's like mine, I still prefer vulkan. I will do more testing with DX11, but as of right now here are my latest settings below:

I create a Shaders folder where mpv configuration is located and place the shaders above in it. They can be found here:
