Vulkan Video Backend isn't supported? - Xephyrex - 10-07-2016
My device is the Galaxy S7 edge and of course it supports the Vulkan API, however, in the dolphin emulator, selecting the video backend as Vulkan and trying to start a game would shows a black screen for a second or two and then close out. The only time the game does load, is when OpenGL is selected as the video backend.
Any ideas?

Broken video drivers? To be honest, I don't accept bug reports from any common mobile driver. Vulkan works very well on the shield android TV...

Thanks for the response! How would I be able to discern if I have broken video drivers or not? I'm on stock official firmware (Android 6.0.1 MM)

Is it a nvidia GPU? If not, the drivers are likely bad.
Edit: Oh, it's not android Nougat, so the chance is even worse to get vulkan running :/
To be honest, there is no need to care about Vulkan. The GL driver is likely better. I think you'll see a good performance upgrade on the android-N update. Else, dolphin is hard to use fast.

The Mali-T880 MP12 is my GPU. Any ideas?

For mobile GPU driver quallity:
nvidia > intel > adreno > mali.

So there's no way to solve it then?

Sounds so. Feel free to debug what exactly is broken and to report it to ARM. Bad luck, bug reports on outdated drivers are usually ignored, and there is no way to install the up-to-date drivers from ARM directly. Android is a very locked-in system...

Vulkan backend is on r12p1, logs are not exposing anything interesting that could be reported to ARM. Setting up debugger and looking line by line to see where it breaks could be an only option at this point.

Could you guide me on how to accomplish this? It'd be greatly appreciated. Thanks!
