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Another thing to note is this issue does not happen with the drivers supplied by Windows Update, though they are very out of date.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.
