Forward+ Mode Freezes Godot 4 Editor after GPUParticles2D Editing

Godot Version

4.4 dev5

Question

Editor freezes after a few mins in Forward+ mode, especially when working on GPUParticules2D. Does not crash to desktop, just hangs with the Windows loading cursor. Eventually I have to click on frozen Editor and windows will prompt “Godot Engine is not responding”

This does not happen in Compatibility mode however, editor runs ok but I can’t use things like particle sub-emitters and the remote tab in Comp. mode is really slow.

Some additional helpful info:

  • Windows 11
  • NVIDIA GeForce RTX 3070 Laptop GPU
  • Vulkan 1.3.289
  • OpenGL API 3.3.0
  • NVIDIA Driver 566.36

I’ve done a fair amount of research so this is a bit of a desperation post but here’s what I’ve tried:

  1. Tried 4.3 stable, same issue
  2. Tried other projects & created a new project, same issue
  3. Removed GPU Drivers via DDU and reinstalled drivers, same issue
  4. Booted from console, no errors both at boot and when Godot hangs
  5. Rolled back the last Windows update
  6. Deleting cache files in appdata/vulkan folder

I can’t correlate it to anything in particular (like a Windows update) but clearly something up with Vulkan on this laptop.

Looking for advice or tips for more debugging or if anyone has run into this issue!

In case any stumbles into this, I eventually had to keep reverting back my NVIDIA driver versions until Godot stopped freezing.

For me that was:

  • 552.44 which installed Vulkan 1.3.277

I’m also seeing this very same issue with pretty much the same setup (mines an RTX 3060 Laptop GPU though). It only started happening after the last NVIDIA driver update.

I don’t have the option to revert my driver though. Compatibility mode fixes it for me, but it’s not a fix.
