Godot v4.3.dev (0bcc0e9) - Fedora Linux 39 (KDE Plasma) - X11 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 (nvidia; 545.29.06) - 13th Gen Intel(R) Core(TM) i9-13900K (32 Threads)

Issue description

When baking LightmapGI, I always get a warning message:

WARNING: There's already a RenderingDeviceDriverVulkan instance doing PSO caching. Only one can at the same time. This one won't.
     at: pipeline_cache_create (drivers/vulkan/rendering_device_driver_vulkan.cpp:2198)

Assuming this is a limitation we can't lift (and not a bug), I suggest silencing this particular instance when baking lightmaps since it's not relevant information for end users here. This could be done by moving it to print_verbose() or having a property to disable the warning in local RenderingDevices.

PS: The warning message could also mention which instance of the RenderingDevice it is (e.g. with an object ID), so you can distinguish it when multiple local RenderingDevices are printing it.

Can you confirm if #87340 fixes it? It'll specifically disable PSO caching for other instances that aren't the singleton of RD.

That fixes it, thanks 🙂
