Phoronix: NVIDIA Improving wlroots For Better Dual-GPU Gaming Performance

A NVIDIA engineer has opened up a merge request to improve the wlroots Wayland library so compositors based on it can enjoy better gaming performance for dual-GPU systems, namely around laptops sporting a discrete NVIDIA GPU but can help other GPU hardware/drivers too...

didn't know wlroots is hosted on freedesktop.org. but the sway itself is on github

That's a good way to push a standard wayland compositor framework I think.
Sway is only one of the alternative wlroot based compositors so no need to reason it on freedesktop.

Nice! I wonder how good this is with dual dedicated gpus. vfio scenario comes to mind

Does it mean that Nvidia is actually planning to release proper dmabuf support as well?

[dreamcat4]

wonder if this could be applicable to the kwinft compositor

This has been a confusing topic to me. At first I read that Nvidia could not support dmabuf through their propietary drivers because it's GPL only; then I read that they support it; then, that they're improving it's support; then, that they still don't; later, that it's not the real DMABUF.

I honestly don't know the status of this.

If wine wayland driver got merged full nvidia performance on par with Xorg im shifting totally to sway.

Ever worked in a for-profit environment, trying to gain clout?

As is the nature of Wayland compositor ecosystem. No it isn't applicable. The work will need to be duplicated/maintained separately.
