This happens on every browser I've tried: I load a 4K60 video on YouTube and there are dropped frames on Firefox and very sluggish scrolling on Edge (likely the same on other Chromium-based browsers), the video even stops to "buffer" when scrolling the page with the video window in view. This happens with every Adrenalin version I've installed up to the most recent WHQL version to date (22.6.1, Windows 11).

An easy solution on Firefox is to go to about:config, search for DXVA and set "media.wmf.dxva.d3d11.enabled" to false. This removes the stuttering and makes everything smooth, as it should be, but CPU usage goes up quite a bit.

Another thing to note is this issue does not happen with the drivers supplied by Windows Update, though they are very out of date. This issue also doesn't happen at all in the Linux distributions I've tested in the same system, so it seems to be exclusive to recent Windows drivers.

The system: Ryzen 9 5900X, 64GB DDR4 3600MHz (4x16GB; this also happened with 2x16GB at 3200MHz), ASUS TUF Gaming B550M-Plus (Wi-Fi), PowerColor Radeon RX 6900 XT Red Devil, Windows 11 (also tested on Windows 10). Tested with PCIe Gen 3 and Gen 4 modes, ReBAR enabled and disabled as well as Gen 3 and Gen 4 NVMe SSDs as boot drives. I had a Vega 56 in this system prior to this card and none of the previously described issues happened at all.

24.12.1: Team green's new cards are far too expensive and AMD may have nothing to show for the high end in the 9000 series, but "better media encoding quality" is highly appreciated if they deliver what is written in that CES slide. Anyway, no changes. If I stop updating it isn't because I got a new video card, but rather because over these years Windows 11 made a very strong case for Club Penguin, where Firefox just works fine out of the box with this exact same GPU and setup.

I know that AMD doesn't pay much attention to these forums, I'm writing this for other users looking for video card options. I've had a blast playing my backlog of games on the 6900 XT and I can enable all avatars in VRChat (within reason, of course; think 20 to 30 people in a mix of Good to Very Poor avatars) without crashing and burning, but when gaming is out and video is in, it doesn't work well in Windows and it hasn't been significantly improved upon since the initial post in 2022.

Same for me. I moved my gaming, audio production and developing activities to Linux, which works well enough for most of what I do. All thanks to Steam, Wine and Proton.

But that's probably not a solution for every one and every need. Still worth a mention.

Hi there! Same problem here. My notices.

Main case: YouTube drops frames when resolution is 4K (30 or 60 fps) and YouTube is not in full-screen.

Browser that I tested issue in both of them: Firefox and Edge.

My setup: RX 7700XT and 144Hz 2k monitor.

My workarounds that fix the issue:

1) Change the refresh rate to 60Hz

2) Start the video when refresh rate is 60Hz and then change it to 144Hz. But video stills play okay.

3) Enter the full-screen, obviously it also fixes the issue. But usually I watch not in full screen.

My notice when I run with the frame drop issue. Video Codec Engine utilization is super spiky. But when I run it without the issue, utilization is stable and the same as 50%.

I literally have no idea why that happens, looking for some help.

This probably won't solve the issue, but a good practice is to set the refresh rate to 120Hz when watching 30 or 60fps content while maintaining a fluid user experience, 144Hz results in improper frame pacing.

The only RDNA3 GPU I have is the ROG Ally, that one is all over the place when it goes to playing videos on Firefox, both of the bodges we figured out in this thread don't work to fix the stuttering (drivers are up to date, I use the official ASUS provided ones).
