Vulkan progress report and initial impressions


So it’s already a couple of days ago since Vulkan launched. We were one of the first non-test programs in the world to launch on Day One with a quite mature Vulkan implementation. So far it seems only ARM Mali, nVidia and Intel Broadwell Mesa drivers can handle all the features inside RetroArch’s Vulkan backend.

This is a followup to the earlier article which can be found here.

WSI XCB support

Back when RetroArch added Vulkan support on Launch Day, there was only a working Wayland implementation.

We support Vulkan over XCB now too. This means you can get Vulkan to run now on Linux with an nVidia GPU since their binary  blob driver doesn’t support Wayland.

I have tested the XCB context successfully on an Intel Ivy Bridge GPU as well. You need DRI3 support in order for this to work.

In case the Vulkan driver does not work for you on Intel, try creating the file ‘/etc/X11/xorg.conf.d/20-intel.conf. The file can be found here.

We recommend that if you have the option to choose between the two (and on some GPUs you simply might not have this option, like nVidia), that you pick Wayland over XCB and an X11 server. It’s a lot smoother.
