> If I pretend these two things don't exist, the smoothness during gaming is far superior though..

Really? I find Wayland way worse for gaming. Like there's a few extra frames of delay or something. It _really_ messes with me and I can't stand it. It's why I'm still on X11 for now.

That's really weird... I play Rocket League on 144 frames and X is far more janky.. while Wayland keeps a very smooth 144 99% of the time, and input delay feels non existent but on X it feels like 2-3 frames behind.

Did you mean seconds? 2-3 frames on 144 FPS would be roughly 17 ms which I think is too short for a human to notice.

Also, did you enable VSync on both the tests? And the same form of VSync? That can have an impact on input lag.

I can notice audio and video being 50ms out of sync. Surely when interacting one could do better.

edit: I recall reading about timing experiments. IIRC good participants could get down to 10ms accuracy when trying to time moving their finger to a signal.

Ah, I think I was confusing the human notice time (is that a thing?) with the human reaction time. Thanks for correcting.

Yes reaction time is around 100-150ms. The experiment I read about was specifically about testing the accuracy of planned motion, which as mentioned was way better.

hmm... It was fairly un scientific.. I will try VSync and report back. I would prefer to use X tbh, because of these bugs. It's certainly not seconds behind, but yea, maybe more like 50-100ms instead of 17.

On NixOS/KDE/Wayland with my 3070 ti, my gaming experience is admittedly excellent. Disabling V-Sync ingame, I get the same latency I did on x11, same performance, with much better frame pacing and VRR support. Strictly comparing across protocols, Wayland is what I prefer to game on. YMMV.

Nvidia's drivers are flaky and deserve their own condemnation, but that's a problem no matter what you use. You won't escape Nvidia's enormous firmware files and driver jank even if you run your machine headless.

It has really low latency on Steam Deck OLED, so it seems not to be fault of protocol, but either your HW or compositor.

Steam deck is AMD, not Nvidia. I was surprised that the parent had good performance in games with Nvidia+Wayland.

Edit: I did a quick Google search, and your comment is dishonest. Many people are complaining about input lag on the steam deck. They've even measured it [0]

I specifically said OLED, yes the LED model is not so great. The improvement across board is described eg. here https://www.eurogamer.net/digitalfoundry-2023-steam-deck-ole...

Yeah, look at the input lag in your link. If you enable the frame limit it goes to shit. It's unclear to me if this is Wayland's fault or Valves fault or a mixture of both. The new version doesn't fix the issue, it just reduces latency somewhere else so all the latencies go down.
