Yeah, this particular experiment doesn't reveal much because the Nvidia driver is a black box. We know in the past it used its "composition pipeline" in Wayland situations, and that was a particularly noticeable increase in latency. Plus, for a while the Nvidia driver also was stuck on software cursors. And even on the DRM path the big two compositors only updated input once every frame, which was the reason for it "to have much worse input lag."
replyedit: I should also point out the mouse acceleration curve, which if you don't fix it is different between X11 and Wayland compositors. That really messes up the "feel" of things.
AMD's Mesa drivers are better, but if you already have an Nvidia card then you can still use it just fine with Wayland.
replyThe biggest hit is Vulkan performance (~20% less than Windows iirc) but for desktop and casual gaming use, Nvidia's proprietary drivers are perfectly fine.
Seconding this. I'm not happy with the fact that the drivers are proprietary, I really prefer FOSS. But, I am tired of having to deal with FUD around performance and issues with NVIDIA devices which simply don't exist at scale.
replyI have friends who are stuck on Windows not because they play games with Windows-only anticheat, but because theyve been told by GNU heads that NVIDIA drivers simply don't perform acceptably on Linux.
Firefox is software rendered on linux-nvidia which leads to a bizarre situation of simple web animations lagging on decent computers.
replyI'd say it's deserved, not FUD. Nvidia did improve in some ways, but it's still way too heavy into blob even in case you plan to use it in the future with nvk. Nouveau / nova developers explained that Nvidia pushed a lot more into their firmware than AMD, turning the kernel driver into more of a shim than an actual driver. That's already a big downside.
