Godot Version
Godot_v4.5.1-stable_win64
Question
I am experiencing a consistent 30-second freeze when launching Godot 4.5.1 (both Standard and .NET builds), as well as a 30-second delay when running any project — even an empty scene. And laso 30-second delay when opening the project. There is some hook or something what prevent to run godot smoothly.
I have RTX 5070 setup, newest drivers.
The editor always hangs at this exact log line --verbose:
NVAPI: Disabled G-SYNC for windowed mode successfully
30 seconds nothing
Then the rest
In Windows Safe Mode, Godot launches instantly with no delay, which means something in normal Windows boot is interfering.
WHAT I HAVE ALREADY TRIED (NONE OF THIS HELPED)
-
Multiple Godot builds & rendering drivers
Godot 4.5.1 standard build
Godot 4.5.1 .NET/Mono build
Vulkan backend
OpenGL backend (opengl3)
ANGLE backend
Delay remains exactly 30 seconds in all configurations. -
Clean NVIDIA driver reinstall (DDU)
-
Attempted NVIDIA Studio driver
-
NVAPI disable attempts
DisableNvAPI = 1
NvJobSchedulerApi = 0 -
NVIDIA Control Panel (per-application settings)
Monitor Technology → Fixed Refresh
Vertical Sync → Off
Low Latency Mode → Off
Preferred Refresh Rate → Application-controlled
Threaded Optimization → Off
Power Management → Max Performance
Triple Buffering → Off -
Disabled Windows fullscreen optimizations
-
Disabled overlays & background apps
Steam overlay disabled
Epic overlay disabled
Discord overlay disabled
NVIDIA overlay disable
OBS closed
GOG overlay fully disabled
Bitdefender disabled
No controllers connected
Second monitor disconnected -
Vulkan implicit layers cleanup
Checked all Vulkan registry locations — removed GOG Galaxy Vulkan layers.
Only remaining layers are from OBS and Steam, both valid. -
New Windows user profile
-
Process Monitor deep inspection
Recorded full startup trace in Sysinternals Process Monitor.
Filtered for long-duration operations.
No I/O operation, no registry query, no file read, no process activity took anywhere near 30 seconds.
Delay seems internal to NVAPI or a blocking call inside the NVIDIA driver, not visible to ProcMon.
Still no root cause found.
Nothing helped… stil 30 seconds every time I want to run project or godot or so… editor is smooth and fast - I am playing newest games no problems, no problems in other applications.
Thank you guys
