Multiplane overlay issues

My issue is with youtube playback or even anything that uses chromium like steam store. Getting really nasty slowdowns when scrolling while I've got a video running on either chromium based browsers or steam store which is also using chromium. Got a RTX 3060 and games work ok with mpo enabled but stutter here and there and I feel like there is also more latency. I know there is the mpo disable reg that fixes this but I'm curious how is everyone else's experience with this issue. Is there no other fix but to disable mpo? Using latest driver and windows 10 fully updated. Never had these issues before because I recently upgraded from a gtx 1060 and pascal based gpus don't support multiplane overlay.

 

MPO seems just plain broken with at least Nvidia, it even introduces stutter for me with single monitor in madVR/mpv fullscreen. Can only imagine how bad it must be with multi monitor.

 

Wow so I'm not going insane. Spent hours trying to fix this issue without using the disable reg file. Even reinstalled windows on a spare drive I had and still the same. In the end I gave up and disabled it and now everything runs perfectly. Funnily enough I posted a similar thread on /nvidia on reddit and my post got deleted in 5 minutes by nvidia mods. Would love to hear from more people if anyones actually got it running fine.

 

its not a driver issue, its an engine issue.

Fix is coming
1132392 - Split UI and HTML content into separate swapchains - chromium

 

Thanks for the info. Didn't find that link when I was looking around but I'm glad it's being worked on. I wonder what is taking them so long considering this issue is not present on firefox(i know they don't use the same engine).

 

i have the same problem, i'm change my old gtx 1060 from a new rtx 3060 12gb, if a dont disable mpo, all programs from adobe have shuttering, cursor slow and lagz, if a disable MPO, the problem is solved, but new problems apear, a netflix is full stuttering, i cant see.... i'm too reseted my windows, 2x.... if someone descovery a solution, tell me please..... actualy i'm ussing with mpo enabled and the g-sync OFF, its the unic way to use adobe programs withtout lag, and without turn off the mpo.

(sorry for my bad english, i'm a brazillian guy)

 

I just checked with dxdiag and it says MPO MaxPlanes: 4.Anyone know if that means its enabled/disabled?I legit tried messing with it at one point but forgot what I left it on.

 

its enabled

 

Thanks.

 

So mpo still causes stutters in games if you have chrome running in the background?
I remember mpo getting some attention like a year (possibly 2 years ago) and the fact its still not fully fixed is amazing.

 

no, chrome itself stutters.

HAGS causes browsers to stop rendering video when a high framerate game is running.

 

i dont use o chrome, but i use the app of netflix and have the problem of glitch and stutters, and in the opera too, if a yanna watch amazon prive have the same problem... this problem is beauce disabled the mpo... when i ative the mpo the problem go way

 

VRR enabled display? MPO is a requirement for VRR in such video apps in fullscreen.
But I don't think they are free of stutter for me with MPO VRR either, also not with disabled HDCP. Amazon Prime app looks smoother on my disturbingly slow Gemini Lake notebook @48Hz than on my Nvidia system. I think the Nvidia driver is just notoriously bad with such things...

 

it does still cause stutters. i worked around the issue by disabling hardware acceleration for my chrome

 

Are you aware that you can disable MPO instead?

Interestingly, my DXDiag says: MPO MaxPlanes: 1
It's an RTX3080 , Windows 11 22622.590 , nV: 516.94
I checked, and I have no OverlayTestMode entry in the registry (so it should be "default").

 

I had the same with my RTX 3090, disabling NIS (Nvidia Image Scaling) in control panel set back MPO MaxPlanes to 4.

 

I never enabled NIS.

 

Are you running 10 bpc color depth? That turns MPO off for me.

 

No, but yes: the main display is set to 12 bit, so that should be it then. But I wonder why. For one, MPO is fairly new but 10-12 bit displays are fairly popular nowadays. And then someone mentioned Netflix stutters with MPO off but Netflix is full of HDR10 content and they suggest 10 bit output (if available) for watching those. But then Netflix did stutter for me the last time I tried (so I kept to my TV's built-in app).
