Wayland feels sluggish with Vulkan compared to OpenGL

Tested versions

4.3

System information

Godot v4.3.stable - Nobara Linux 40 (GNOME Edition) - Wayland - Vulkan (Mobile) - dedicated NVIDIA GeForce RTX 3050 Ti Laptop GPU - 11th Gen Intel(R) Core(TM) i7-11370H @ 3.30GHz (8 Threads)

Issue description

While Wayland feels fantastic in general for me on Linux, in Godot something has felt "off" ever since I've begun testing it. It's not bad, but it's not as smooth as the rest of my Gnome desktop experience.

Now I have some stats to back that up:

Also, I thought I had a 120hz screen, so it's weird to see it go higher... it's a Microsoft Surface Studio laptop so it's one of those which switch between an Intel GPU and an Nvidia GPU... (I wouldn't mind keeping the Editor at 60 to save on resources, btw).

Steps to reproduce

Run Godot with the flags from here, and test with "prefer wayland" on and off (with restarts in between).

The reported FPS can't really be trusted when low-processor mode is enabled, which is the case in the editor unless you enable Update Continuously in the editor settings.

I suggest doing that and reporting back on both XWayland and Wayland. This way, we can know if low-processor mode is the culprit.

(I wouldn't mind keeping the Editor at 60 to save on resources, btw).

This can be done by setting Low Processor Mode Sleep Usec to 66666 in the Editor Settings. It will only be effective when Update Continuously is unchecked.

The reported FPS can't really be trusted when low-processor mode is enabled, which is the case in the editor unless you enable Update Continuously in the editor settings.

My bad, I proposed measuring FPS and forgot about low consumption mode :sweat_smile:

Ok, so I toggled that "update continuously" setting to ON and measured the following:

And yeah, that absolutely tanked the fps... but weirdly it feels smoother? Is because of frame pacing then? I know you both said that the other framerate couldn't be trusted, but the Wayland reading fluctuated wildly, while the off setting seemed more stable...

PS. I've now also changed the sleep setting and that further reduced the framerate to 15? Feels weird...

Mhh... That's interesting. Your GPU is quite beefy and I can't seem to replicate this with a simple 3d scene on sway, running in debug mode on an AMD iGPU.

I know I'll sound like a broken record, but I really hope it's not nvidia-related once again. I don't remember if we already talked about this, but just in case make sure to have the latest driver version if that's not already the case.

Let's do some quick consistency checks and try narrow it down in the meantime. If you say that everything is quite smooth, I'd try OpenGL (--rendering-driver opengl), since basically every other (non-xwayland) program uses that. Maybe there's something wrong with the Vulkan stack. I remember that nvidia's implementation has always had some weird quirks, even on X11.

Otherwise I'd also test performance with the intel iGPU. The easiest way is probably passing --gpu-index 0 when using Vulkan (the ids start from 0 and your dGPU is marked as number 1).

Haha... it's super smooth using opengl... so yeah, probably Nvidia again then... and unfortunately I just ran all updates too... that open source driver can't be ready soon enough so we can kick their neglected proprietary crap out!

(Btw, I toggle update continuously ON halfway through and this time I see the expected 60fps, but using the default sleep setting, not the suggested 66666 value.)

EDIT: Oh, seems the opengl mode stays on Intel? I don't see (because I also have an extension to check) the Nvidia GPU kicking in...

Thanks for testing! This is a bit annoying... I'm not sure what we can do here.

EDIT: Btw... seems the opengl mode stays on Intel? I don't see (because I also have an extension to check) the Nvidia GPU kicking in...

Yeah, you're right. Check the log:

OpenGL API 4.6 (Core Profile) Mesa 24.1.5 - Compatibility - Using Device: Intel - Mesa Intel(R) Xe Graphics (TGL GT2)

I'm not sure if the half-broken DRI_PRIME prober port is causing issues here of if it's simply refusing to work. Does the GPU kick in with other applications? You could try setting the DRI_PRIME environment variable to 0 since it's using 1.

DRI_PRIME=0 godot (and so on)

Edit: wait, I'm not even sure it's actually using 1. For all we know it might be defaulting to 1 and then we override to 0, so please try both 0 and 1.

Unreal kicks off the Nvidia GPU immediately, but I'm only on 5.3 and I don't think it has proper Wayland support (same blurry font rendering as if I switch off Wayland in Godot). I tried Exhibit which has Wayland support and that did not activate the Nvidia GPU... 😥

So weirdly, both of these triggered the Nvidia GPU... and they felt basically the same too... steady frame pacing but not too high frame rate.

Can I force the editor to use OpenGL without resorting to command line arguments?

To clarify, DRI_PRIME only affects OpenGL, not Vulkan. And it's not supported by Nvidia AFAIK, this is something used by Mesa and thus only open source drivers (Intel/AMD).

For Vulkan, you can instead use the --gpu-index command offered by Godot. Or set which ICD to use with VK_ICD_FILENAMES.

Can I force the editor to use OpenGL without resorting to command line arguments?

Yes, by making a GL Compatibility project.

Thank you for the information!

Here is what I got using those parameters instead, first index 0 (oh, and with added verbose too which apparently lists my devices):

Now, in the middle of the index 1 test I switched the project from mobile to compability and yeah, it's such a night and day difference in perceived smoothness with OpenGL + Wayland!

Uh oh, it crashed. Does this happen constantly? I'm really not sure why it's crashing when using the Xe GPU with Vulkan.

Only in mobile mode (started in compability and then switched to mobile to re-trigger crash):

@eobet that's quite weird. Could you pass me a wayland debug log while it crashes? If I'm not mistaken it's trying to say that the window's scale is wrong but I can't see why it would happen only on vulkan.

I've heard that the Xe driver is still in development but I'm not sure that's it. Does it crash with vulkan on X11?

On another note, if we can confirm that vulkan Xe is not sluggish on your machine I think that we can assess the actual issue of this thread as an nvidia issue, although I'm trying hard to not come to conclusions.
