Terrible anti-aliasing with AMD gpus?

[AlasPoorJoric]

Anyone know why when using an AMD gpu there are terrible jaggies using the link cable or airlink (not for Virtual Desktop)?

It's exceptionally bad when using the Oculus virtual desktop. The edges of the screens look not only like they lack antialiasing, but are so crudely blocky the edges remind me of 640x480 gaming from the '80s, and constantly move and shimmer like a busted escalator as you tilt your view.

This is also very noticeable in edges of objects on some games (Wanderer for instance is pretty awful), though not as bad as the desktop screens.

I've messed around with resetting to default settings, changing rendering resolutions in the Oculus desktop app (currently 3936x1984) and debug tool (also the default codec), then going through the antialiasing options and override options one at a time in the Catalyst settings, but to no avail.

I just switched recently to an RX 6600 XT and due to this it's a major downgrade in visual quality from the GTX 1660 Ti I was previously using, despite the raw performance being about 50% better in terms of frame rates and thus allowing higher settings.

Nvidia GPUs have considerably better hardware video encoders than AMD GPUs of that generation. While you may have more rendering power now, the cards ability to convert it into a video stream to send to the headset is lacking.

That would make some sense, and I'd read that the H264 encoding in particular is comparatively weak with AMD GPUs, but Virtual Desktop is still encoding their video stream and it doesn't seem to have this issue.
Nor does switching between H264 and H265 manually with the debug tool seem to make any difference.

that's not true anymore. The problem is with meta, where I decode better with nvidia and they even write somewhere that nvidia is preferred over AMD... According to that, it looks like that

Hi there, @eRHoodx and @AlasPoorJoric! Having clear visuals can really contribute to the VR experience overall, so we wanted to be sure to drop in with some troubleshooting steps that may help for this type of display quality issue! If you haven't already tried, please complete the following steps:

• Make sure your GPU drivers are up to date.
• Confirm that your PC meets the proper requirements to support Meta Quest Link.
• Disable any VPNs or antivirus that could be interfering with the headset's connection.
• Remove any extra USB devices from the computer except for what's necessary (mouse, keyboard, and Link cable,) then restart your PC.
