Describe the Bug

Hi,

I ran some tests with the new Vulkan encoder (#4603) using an RTX 5070 Ti on Bazzite (KDE Plasma 6).

When I force the Vulkan encoder, I get a black screen upon connecting to the host. From the logs, it appears that Vulkan is attempting to use my CPU's integrated GPU instead of the Nvidia GPU.

I'm not entirely sure this qualifies as a bug, since most Nvidia users probably don't force the Vulkan encoder, but I thought this behavior might be useful feedback to help improve the reliability and device selection logic of the Vulkan encoder.

Environment:

• GPU: RTX 5070 Ti
• OS: Bazzite
• Desktop: KDE Plasma 6
• Encoder: Vulkan (forced)
• Result: Black screen on connection

I've attached the logs below in case they help with troubleshooting.

Thanks again for your work on Sunshine

Hi, if there's an appImage build, I'll test it today and let you know if it works.

Thanks for your quick response!

Hello, proposed the PR here #4961 . Could you test it please and give a feedback?

This time at least it's looking for another encoder if Vulkan isn't available.

But it didn't work for me.

It seems that the gpu selection patch worked. It tried to use Nvidia GPU. Your system (Nvidia driver) doesn't have Vulkan encoding extension probably.

Doesn't the appImage use its own version of Vulkan? (Sorry, I really don't know anything about this part; isn't it a dependency that's built?)

Doesn't the fact that it's done in an AppImage change the dependencies used?

I'm new to Linux, and I find these dependency issues with OS packages much more complicated to understand.

Could you run sunshine from the command line directly (not as a service) using path to AppImage with this var?:

I was able to launch it (I first exited the service version), but on the other hand, it's impossible for my host to be found by my client (even by forcing it with the host IP).

It didn't pick up the config. Would be possible for you to run standard sunshine? Or use the command:

env VK_LOADER_LAYERS_DISABLE='*' /path/to/sunshine.AppImage ~/.config/sunshine/sunshine.conf

env VK_LOADER_LAYERS_DISABLE='*' /path/to/sunshine.AppImage ~/.config/sunshine/sunshine.conf

I tried to log in at 4:53 PM and it can't find the extension.
