  • I have a 3090 and just swapped over to the beta 555 drivers and Kwin with explicit sync patches applied (the patches will be available out of the box with Kwin 6.1). Honestly, the Wayland experience is basically flawless now for most cases. The only bug I am experiencing is Steam shows some corruption in the web views on start up until I resize the window, but it’s a minor quibble in exchange for getting Wayland. I expect most of the minor remaining issues to be hammered out quickly.

    Honestly, I’ve had genuinely bad experiences with AMD. I hated my unstable Vega 64 that would crash almost every day and was much happier when I finally ditched that card for my 3090. My laptop has a Radeon 680M and that would regularly have hard system hangs, broken video acceleration, etc.

    Besides that, I also think being part of the AMD ecosystem is difficult at times. FSR sucks compared to DLSS, raytracing is sub-par, there’s no path reconstruction equivalent. From a compute perspective, ROCm is unstable. Even running something as simple as Darktable with ROCm would cause half of each of my photos to not render out properly. Blender with Optix is much faster than Blender with AMD HIP. If you want to do AI, forget AMD as the ecosystem has basically gone with CUDA.

    And yeah, the lack of HDMI 2.1 means no 4k 120Hz VRR on a wide variety of displays. Everyone says “why not display port”, but it is tough finding a DP capable monitor with the right specs and size sometimes. For example, try finding an equivalent of an LG C2 that has DP. There’s only one, its by Asus, and it costs $600 bucks more.






  • You’re correct. While the stable version of KDE Wayland is usable right now with the new driver with no flickering issues, etc., it technically does not have the necessary patches needed for explicit sync. Nvidia has put some workarounds in the 555 driver code to prevent flickering without explicit sync, but they’re slower code paths.

    The AUR has a package called kwin-explicit-sync, which is just the latest stable kwin with the explicit sync patches applied. This combined with the 555 drivers makes explicit sync work, finally solving the flickering issues in a fast performant way.

    I’ve tested with both kwin and kwin-explicit-sync and the latter has dramatically improved input latency. I am basically daily driving Wayland now and it is awesome.
