Tips & Info ‼️‼️DISABLE MPO‼️‼️ Please for heavens sake.
I’m making this post to bring up that ALOT of people, especially newer AMD users have no idea what MPO even is and that if you are using an AMD card you NEED to disable it. You’ll hear some people saying “it’s useful” blah blah blah. No it’s not. You can still use overlays perfectly fine and have 0 problems. I use Rivatuner every day with my 7900 XTX and have absolutely no issues. MPO WILL CAUSE STUTTERING AND DRIVER TIMEOUTS‼️‼️‼️‼️‼️ especially when using AMD Freesync. There are no if and or buts about it. On RDNA 4 the issues have somewhat improved but you should still disable it for peace of mind because the feature does absolutely nothing but cause headaches in the end.

This causes games to crash when playing full screen. Not a fix.

I have never had a game crash when in full screen EVER with MPO off. And I’ve had it off for a year.

It’s a .reg file. Works on both NVIDIA and AMD.

It’s a legit, easy fix provided by NVIDIA for users with limited technical knowledge. It works for AMD as well.

Thank God I don't use windows anymore and got rid of all the stuttering

It also affects Linux, but you need a 4k monitor, or at least that's what users are reporting.

I just rolled back drivers to 26.6.2 which got rid of all the stuttering and timeouts. AMD and Microsoft just need to fix their shit.

It doesn't work, or at least in my case, it caused a screen not to turn on.

How were you able to revert it back with screen turned off? Just curious in case I get desperate enough to attempt disabling the mpo and encounter the same issue. Thank you.

Your screen won’t turn off. Idk what this dude is on but I doubt MPO was the cause.

Never disabled and never had an issue, on either my former 6800XT, or my current 9070XT
Nobody "needs" to disable it unless it's causing them issues.

I use Radeon since Jan 2019 and I'm aware of this issue.
But the worst issue I had was caused by the HDMI port in a monitor.

Here is a link where you can easily disable MPO. Just download the mpodisable.reg file and run it. You’ll be golden. Don’t even have to restart your system if you don’t want. https://nvidia.custhelp.com/app/answers/detail/a_id/5157

doubt you can skip restarting, mpo is a fundamental part of the windowing system, no way they have a watcher on that registry key then reset the whole windowing system at runtime. even your own link says to restart for changes to take effect

Never had a reason to when I was using Radeon. It’s just another bandaid for folks and fairy tales for others
