Godot: Vulkan: Crash

[zaksnet]

Godot version:
d6abb52dba5c471e8bfe47a2f2d0c236c85c0652 (Vulcan)
OS/device including version:
Windows 10 1903
Issue description:
Get stuck when trying to open (a) the project:

Steps to reproduce:
Happens with any project for me and since this is the 10th time (:grin:) i compile Vulcan to test it ( just wanted to test 2D, which from what i understand is ready) though i could create an issue this time!

What is you graphics card and drivers?
Seems that drivers are too old or just doesn't support some Vulkan extension yet

[zaksnet]

@qarmin can't believe I forgot to add my graphics card in the post :persevere:.
It's Intel HD Graphics 620 and as seen in https://vulkan.gpuinfo.org/ it supports Vulcan. My drivers are on the latest version 26.20.100.7372

[qarmin]

I'm not sure but probably Godot need support of Vulkan 1.1.127(https://github.com/godotengine/godot/commit/fe2bac39b0d2d58c584343e4b2c315957a1af45b) but this drivers only provide 1.1.120 (http://www.geeks3d.com/20191031/intel-graphics-driver-26-20-100-7372-released-vulkan-1-1-120/)

You can try compile Godot with this commit https://github.com/godotengine/godot/commit/5271e79896447208e83f960b3c4febe5e6584c40 because this require Vulkan API 1.1.113 which should be supported by your graphics card

[qarmin]

I was wrong. I just checked and I have Vulkan 1.1.114 on GTX 970 and Ubuntu 19.10 and everything works fine.

Error seems to be from the validation layers initialization, and likely they are not available in the client drivers.
Missing validation layers probably shouldn't affect anything, but try installing Vulkan SDK anyway, at least it should give more verbose run-time error messages from the VK_EXT_debug_report layer.

@bruvzg , After installing the Vulkan SDK I'm getting the exact same errors :/. Should i add the VK_EXT_debug_report extension somewhere in the code?

Also installed the runtime:

[bruvzg]

It should be loaded by default (looks like there's no "registry lookup failed" warning on the last screenshot, so layers are loaded).

Do you use GLES3 in project.godot? For me it crashes with GLES2, maybe that's the issue (it also showed leaks).

Only valid values for the video driver are "GLES2" and "Vulkan", but if it's set to any invalid value, like "GLES3" for example, if will fallback to "Vulkan".

If it's set to "GLES2", Godot will try to actually use GLES2 driver (which is not ported to use new features and currently is non-functional in the vulkan branch). No vulkan or Rasterizer*RD errors should be visible in this case.

Closing as this is an old issue about the incomplete and unstable Vulkan branch.

If you can still reproduce this issue in today's master branch, please open a new issue.
