and everything freezes.
replacing the vsw2xnvk.dll with the one from r3 everything works fine an no freezing.

Any idea what my cause this?
I'm a using Geforce GTX 1070ti 8GB VRAM (driver version 466.47) on Win10 x64 21H1 (19043.1023) with 32GB RAM and a Ryzen 7 1800x.
Is there some missing dependency for newer ncnn/vulkan I might lack on my system?

Cu Selur

Ps.: completely uninstalling and reinstalling the nvidia drivers didn't help either. (switching to 'Studio drivers' didn't either)

Just tested with r3.2:

• vsedit can now open the script and preview the images (didn't work with 3.1)
• closing vsedit causes a freeze
• vspipe has the same behaviour (freezes)

NCNN is already static linked in vsw2xnvk.dll, and Vulkan runtime is included in graphics card driver, no other dependency is required.

I can’t reproduce this issue on my computer. Based on your test result, I guess the problem is occurred in ncnn::destroy_gpu_instance(). Some NCNN user reported they have segfault in Vulkan API when NCNN implicit excuting ncnn::destroy_gpu_instance(), NCNN developer replied a workaround is call ncnn::destroy_gpu_instance() explicitly. And one of the changes in the R3.1 is to change the calling method from explicit to implicit.

Could you help me test this attachment?

No problem, happy to help.
Tried the attached dll and this version works fine.
I can open the script without problems, as output I see:
during the opening I see:
begin ncnn::destroy_gpu_instance()
end ncnn::destroy_gpu_instance()
same output during closing.
Using vspipe works fine too.
Output looks as expected.

A new version is released.

Thanks for report.
