NVIDIA Bug Report: Vulkan Crash on RTX 5080 with Godot Engine

Summary

Godot Engine 4.5.1 crashes immediately on startup when using Vulkan renderer with NVIDIA RTX 5080. The crash occurs before any scene loads, during Vulkan device initialization.

System Configuration

  • GPU: NVIDIA GeForce RTX 5080
  • Driver: 591.44
  • Vulkan Version: 1.4.325
  • OS: Windows 11
  • Application: Godot Engine v4.5.1.stable.official.f62fdbde1

Reproduction Steps

  1. Install Godot Engine 4.5.1 (Forward+ / Vulkan renderer)
  2. Create empty project with minimal scene (single Node3D)
  3. Run project with RTX 5080 as primary GPU
  4. Crash occurs immediately after device selection

Crash Details

Vulkan 1.4.325 - Forward+ - Using Device #0: NVIDIA - NVIDIA GeForce RTX 5080
[signal 11 - SIGSEGV]

Crash occurs after WASAPI audio initialization, before any scene resources load.

Workaround Confirmation

The same project runs perfectly on:

  • AMD Radeon integrated GPU (Vulkan 1.4.315) via --gpu-index 1
  • OpenGL 3 renderer (--rendering-driver opengl3)

Minimal Test Case

; project.godot
config_version=5
[application]
config/name="Test"
run/main_scene="res://empty.tscn"
[rendering]
renderer/rendering_method="forward_plus"

; empty.tscn
[gd_scene format=3]
[node name="Node3D" type="Node3D"]

Additional Notes

  • Crash is 100% reproducible
  • Godot editor also crashes with same GPU
  • Issue specific to RTX 5080 + driver 591.44 combination
  • Other Vulkan applications (tested: vkcube) work correctly
