Since it's not presentation in advance I'm not sure if the same logic applies. I know the old Windowed Overlay mode in madVR is actually stutter-free for me with 3 backbuffers on a Turing card. (And this stuttering nonsense started for most people when Turing came out.)

Thanks buddy, I must have skimmed over swapchain-depth when doing another dig at the reference manual yesterday.

swapchain-depth=1 solved the vsync issue with the d3d11 API.

Not when using the Vulkan API though. I tried vulkan-queue-count=N with several values (default 1) with and w/out vulkan-swap-mode=fifo and/or swapchain-depth=1.

Doesn't matter that much, it's more a curiousity thing at this point, d3d11 is fine .

After reading several comments and tips from you guys, the best configuration I got to eliminate the stutterings / glitches on my rtx2060, using mpc-hc, lavfilters and madvr was to leave vsync in the default settings, set value "1" in present several frames in advanced.

Even with these changes, I still noticed some glitches and stutterings, which were completely solved when I configured it on the nvidia control panel, exclusively only for the mpc-hc and madvr, in the power option for preference for maximum performance, with that resolved definitely the problem of stuttering / glitch in the system, now everything runs perfectly, everything is soft, but there is a catch, the consumption and temperature of the vga increases a little and maybe, depending on the profile used in madvr, the user may need to reduce some things for vga to hold the performance.

But I'm seriously considering abandoning madvr permanently and start using mpcvr with standard video renderer, because I found it much better than madvr, it is light, works for videos encoded in 10bit and is very simple to configure. I am testing it at the moment, no stutterings / glitches using it, I will do some tests, but it is likely that it will definitely stay on it, just not having stuttering in the videos is already perfect, without having to do or configure anything.

FSE is also not useful in current Windows 10 with current drivers.

It is being emulated in the current Windows 10 so it does not provide the same benefits as it used to. There really isn't a point to use it anymore and it often causes problems. If it doesn't cause problems on your system it is fine to use, of course, but it is not an option I would enable anymore.

madVR works for 10 bit too.

But feel free to use MPCVR if you don't need the other features of madVR, less hassle is a good enough reason.

FSE can be used with latest NVIDIA drivers to keep HDR enabled, because any windows UI element would disable tonemapping on the TV otherwise.

[Asmodian]

Ah, nice, that could be useful.

I still don't like FSE and I don't use the UI elements when I want the tone mapping to work anyway.

[Maryoum]

HDR looks great in Windowed mode but it gets very dim in fullscreen. Any ideas?

The thing about MPCVR for me is that it doesn't support 3dlut, and it lacks more scallers.

When playing a video file with madVr, the whole system restarts within 10 seconds. I've tried 32bit and 64bit, different settings, updated LAV filters, nothing.
I have no issue in games or any type of stress testing the GPU.
What's the problem?

anyone?

[huhn]

you should check the event manager why this is happening.
a video renderer is not really capable of doing this.

980ti doesn't have the HEVC decoder, so if you're running 4K, it's using CPU decode, if that's on the AVX path, it could lead to overheat / instability if you have an overclock.

Anything NOT running avx path won't crash the pc, but avx load would.

you havent given us much to go on here, does it only BSOD when you are playing a movie with the MADVR renderer, if you switch to stock renderer does not not crash?

have you done a full drive wipe and reinstall using the NVIDIA cleanup suggested here?

https://forum.doom9.org/showthread.php?t=176013

have you analyzed the memory dump?

I'm only doing 1080p and CPU is not overclocked.

It doesn't BSOD, it straight up restarts the PC. without any kind of error.
With stock settings it doesn't crash at all. Also yes, I have read the thread you mentioned.
I used to have this issue before with my old GTX 970, after I installed MPC x86 it was solved.
Then I had RX570 it didn't have a problem with either x64 or x86
And this GTX 980ti has problems with both.

Power related, maybe? Power supply, etc...

I managed to monitor GPU power draw while playing using madVr.
It consumes about 300watts.
During gaming, or even furmark test, it consumes well over 340watts and there's absolutely no crashing.
Although I will test with a different power supply to see if anything changes.

if its not even writing a MEMORY.DMP or MINIDUMP it suggests a hardware fault on some level but i have had this a couple of times way back in the past with my RX480 with a couple of driver packages where is would just restart the PC randomly with no dumps, so it is possible for a driver to cause this.

so it only happens in MADVR right?, have you definately done a full driver wipe or both NVIDA and AMD packages, you may still have some driver remnants from bother if you've had other cards installed.

so if you put the RX570 back in its ok?

The answer to all your questions is yes )

[traykov77]

Did you clock your ram speed or changed ram settings, I had crashes before and think that is videocard, but when I put ddr ram to 1333 instead of 1600Mhz I have no problems at all.

you reported similar issues march last year when you were overclocking a 970, have you clocked this one too?

have you tried installing a quick fresh OS build on spare hard drive to test your OS, could just be windows needs a fresh install.

does it do it in all players, have you tried both HC and BE, and KODI DS, or others?

are you running MADVR at stock settings after a nvidia full driver blitz?

Try removing MADVR completely and install it in another location on a different hard drive, ideally not OS drive just as a test.

I think i've had issues like this before a long time ago but I'm sure i managed to fixed them with a combination of driver / MADVR wipe, I did once have to refresh my OS but I cant remember exactly why that was, I think it was when I had issues upgrading from win8 to win10, I wiped at that stage.

If I want my Nvidia GPU to do all the work, must I set LAF Video to one of the 2 DXVA2 options?

And then MADVR Image Scaling Options to DVXA2?

What about Chroma upscaling? I don't see a DXVA2 option there.

[huhn]

except for some very small exception madVR entirely runs on the GPU.

it "get" DXVA chroma scaling you either set it to bilinear and use DXVA image scaling or you use DXVA2 native decode with default trade quality for performance.
i highly recommend you to avoid DXVA2 native and DXVA "scaling" it's really bad.
