AMD, Intel and Nvidia driver issues and last recommended version

[aquanash]

I've been running nvidia driver 536.23 for over a week now and everything appears to be okay except they still haven't fixed the HDR switching issue that's been happening in every version after 525.25. I still have to restart the video card every few days to keep HDR switching working. I made sure to use DDU (safe mode) when upgrading.

Had one brief audio drop, unsure what caused it. Never had any HDR issues.

No DPC latency fix with these so potential to experience audio drop ours still exist. "Next" driver should resolve it based on tweets, currently in QC testing.

[SamuriHL]

That would be nice.

[ryrynz]

Maybe Spotify won't have the occasional hiccup now.. Fingers crossed. Although my latency still appears at the same levels as before being a "potential" issue. Apparently Rebar is a sighted cause for high latency.. as long as my audio doesn't drop through that's all that matters.

Have you tried the latest driver yet? The reboots to fix HDR are driving me nuts.

Every half a minute or couple of minutes, the picture stumbles / stutters / jumps a few frames. Sound is fine. madVR display info doesn't show any frame drops. The issue is random and and always occurs at different time stamps.

With the same setup and a GTX 980, SDR and HDR were fine. Then I changed to a RTX 2070 Super. At first everything was fine. Then with around Nvidia 512.x and/or a Windows update, SDR and HDR were constantly stuttering. This was solved by:
- Vertical Sync to 'On' for the media player exe.
- In the madVR settings, uncheck 'enable automatic fullscreen exclusive mode
- In the madVR settings, how many video frames shall be presented in advance' to 1

Now with the RTX 3080, what else can I try to solve this stuttering with HDR MKVs?

I am still fighting this issue...

- Installed the latest Nvidia driver with DDU.
- Latest LAV filters
- Also tried with latest beta MadVR
- Installed latest updates for Windows 10 22H2

What else could I try?

Can you upload a screenshot playing a problematic file with OSD info?
Use external website like Google drive.

[Goeggel]

Here are the OSD screenshots for 1080p (no stutter) and 2160p (random stutter):

By stutter I mean it looks like a few frames are skipped and as if the movie jumps a tiny bit forward. Sound is always fine.

I let run the 1080p MKV for about 5 minutes and the 2160p MKV for about 15 minutes.

The shown Drop/Rep values for both files were from opening the MKV and then going to fullscreen (MPC-BE player). These two values didn't change during the runtime.

The value for Gltch on the 1080p didn't change during the runtime.
On the 2160p MKV however, Gltch would go higher every now and then. Sometimes I thought the counter went up immediately after a stutter had occured. But sometimes the counter went up and I didn't notice a stutter (they are quite subtle). So I am not sure if it's a coincidence or not.

Have you tried to increase the difference between CPU and GPU cache in MadVR -> rendering -> general settings ? In my setups I always have at least a difference of 6.
Would also suggest to use profiles for varying resolutions.

[ryrynz]

Does turning off subtitles help? Higher madVR caches are a potential workaround.

Which cache settings do you use?

I will check regarding the subtitles.

With cache, do you mean queue size? I have tested with setting the GPU and CPU queue sliders all the way to the right (highest settings). Unfortunately, the stutter was still there.

[ryrynz]

Yeah the queues. Well that rules out one avenue of resolving things. Next step will be to try ruling out the software step by step.

[Grimsdyke]

Just in case your RTX runs into a bottleneck because of whatever reason I would suggest also test reducing the GPU cache/queues down to '8' or '10'.

[huhn]

the usual:
force vsync in the nvidia control center and use a render queue between 1-3.

nvidia pretty much needs these settings to have a chance of working.

[Goeggel]

Thank you all for your inputs! I think I maybe got it to work without stuttering. Not 100% sure as I haven't had time to watch a whole 4k MKV, but it looks promising.

Setting the Nvidia power configuration to "Maximale Leistung bevorzugen" (max power) instead of "Normal" (which was working on the 980 and the 2070S) on the media player EXE seems to get rid of the GLTCH and visible stutter for me.

I already had Vsync on the media player EXE and render queue to 1 since the 2070S.
Turning off the subtitles didn't make any difference. I also tried to disable the GPU acceleration in LAV Video filter and let the CPU do the work, but still had the GLTCH numbers going up.

I noticed that I didn't have visual stutter with every GLTCH, but every visual stutter was accompanied with a GLTCH.
What exactly does the GLTCH mean in madVR?

[el Filou]

Glitches are when another application is using the GPU to draw at the same time as madVR when in (fullscreen) windowed mode.
It could be anything from a desktop app displaying GUI elements to another app displaying an overlay (i.e. Logitech Options does that with my wireless keyboard, or a Windows notification).

Quitting other apps that can use the GPU one at a time until glitches stop increasing could be a way to find out.
You can see which apps use the GPU with Task Manager.

[Goeggel]

"Prefer Maximum Performance" / "Maximale Leistung bevorzugen" definitely gets rid of the Gltch and visual stutters for me. Putting it back to "Normal" and the Gltch and stutters are back.

The downside is that on max performance setting the RTX3080 (and the PC as a whole) get now much hotter than before...

I have tried to find out what hogs the GPU on Normal settings to cause the Gltch, but I don't see anything unusual going on.

What's the consensus on the best nvidia driver to use currently for 23.976 playback and bitstreaming? Card is a GTX 2070S.
