Errors running Godot after building for Windows

kitfox

I decided to checkout the Godot source from github and went through the instructions for doing a windows build. While I can build and start it running, it spits out a lot of errors related to the vulkan. Is there a way to get this working?

ERROR: No render pipeline was set before attempting to draw.

If you pulled master, don't bother. It barely works right now.

What operating system version and graphics card model are you using? Is the driver fully up-to-date and installed from the GPU manufacturer's website (not Windows Update or your desktop/laptop OEM)?

I have a computer that's about 4 years old. It's running Windows 10 with two AMD FirePro W2100 graphics cards. Windows tells me the latest drivers are already installed.

I did pull from master. I know Godot 4's been in development for quite a while now. Do you have any sense of when it might be a good time to pull again and build?

Based on what I can tell from the error, it seems like the error is related to Vulkan initializing. According to this website, the AMD FirePro W2100 supports Vulkan 1.2, so I think it should work, though I'm not sure what version of Vulkan is needed for Godot 4.0 currently.

It would depend on the drivers. I know like my Intel HD 500 system does technically support Vulkan (I think 1.2 as well) but Godot 4.0 just crashes after like 5 seconds. Haven't tried to build from source, just from what I have been testing on the pre-alpha builds. In any case, this Intel system gets horrible performance on Vulkan games (like DOOM 2016) like half of OpenGL performance, so I imagine it is some sort of emulation or compatibility layer and not real hardware support.
