Godot slow to open, slow to edit, slow to launch simple game [Windows, caused by specific USB peripherals]

[nicklunt]

Bugsquad edit:

This bug has been well confirmed as something that's caused by specific USB peripherals and their drivers, apparently triggering an elusive DirectInput bug on Windows which is only reproducible in specific combinations of hardware (both host and peripheral) and drivers. This seems to trigger particularly some brands of USD keyboards, mice or audio devices (especially Digital Audio Converters).

See https://stackoverflow.com/questions/10967795/directinput8-enumdevices-sometimes-painfully-slow which seems to be the reference StackOverflow issue for this problem. We still don't know how to work this around in a way that wouldn't require users to manually upgrade or disable bogus Windows drivers.

Godot version:

3.0.6 from Steam.
Also same issue on fresh download from https://godotengine.org/
This happened on previous versions too. It's been happening for about 3 months or so.

OS/device including version:

Windows 10 PRO x86_64
Version 1803
OS build 17134.167

GPU Nvidia GTX980ti
GPU driver 398.36

Issue description:

Opening Godot from with steam or from native download takes over 40 seconds.
Opening a very simple project in edit mode takes 35 seconds.
Pressing the play icon on this project from within Godot takes 46 seconds before the game window opens.

Steps to reproduce:
I can reproduce this every time just by opening or creating a basic project.
I get the same issues when I launch one of the demo projects, such as multiplayer pong.

Minimal reproduction project:

Here is the minimal project that takes the time mentioned, but I get this issue on all projects.
Hello Godot.zip

I have also attached the output from the cmd windows that opens when Godot is launched.

NVIDIA, huh? I believe there were reports of slow launches on NVIDIA, you could try searching for "NVIDIA" in issues. End consensus was that there is a driver bug.

nVidia GeForce GTX 1060 6GB/PCIe/SSE2 here, Godot 3.0.6 opens fine for me (website non-mono version). I know Godot is slightly slower in some cases with nVidia due to bad auto-performance modes, but not that slow (as in 30-second launch instead of 4).

GTX 960 and 1070 reporting in with same problems. Slooow launch in windows, fast in linux.
I really wish this could be fixed, as it is my biggest issue with Godot. I like to launch my game all the time to test small tweaks, but takes too much time in windows with my nvidia GPUs.

Joining in on the issue with a GTX 1070. Tried all stable releases of Godot. Also tried on 3 versions of the latest driver 398.98, 398.82, 398.36. But I did notice that the first time (after driver reinstall, computer reboot) it started up quickly. I'll play around with some Nvidia settings when I'll find the time. This is a big issue and should be looked up a bit more.

Edit: I'll reconfirm that the first start after a system restart works normally. Every subsequent startup takes long (40s).

399.07 driver is released.
would you test with it?

[nicklunt]

Hey volzhs - yes that seems to have fixed it!
Not had time to do extensive testing yet, but just opened/edited/ran a few games and performance was great.
Thanks for the heads up on the latest driver.

I dont know how it affects but driver release note contains this.
