Yaakuro shows off SteamVR on Unreal Engine 4 using Vulkan on Linux

Previously Yaakuro worked to make Unreal Engine 4 work with SteamVR using OpenGL on Linux, but now he's moved onto making it work with Vulkan!

Amazing to see such progress and I really hope his patches get accepted into the Unreal Engine 4 base.

Unreal Engine 4 does have a lot of Linux issues, since multiple games are blaming engine issues for not coming to Linux yet. Maybe Yaakuro can look into these issues once he's done with his VR work. Article taken from GamingOnLinux.com.

I'm guessing this is what would be required for Alice VR to work within the headset. It currently loads up so you can play it on the monitor... but that isn't exactly VR.

And for what it's worth, I finally managed to get Serious Sam VR: The First Encounter working under Debian with the beta nVidia driver! Still got my ass kicked, but it played smoothly.

I heard that you can use Vulkan in UE4 only by using the "mobile rendering pipeline" or something like that.

Is that what he's doing? Or is this full blown Vulkan support we're talking about?

Quoting: QuenestilIs he working for Epic or is just a fan?

He's not employed by Epic, he contributes patches and bug fixes on his own time. He's been mentioned on here and other Linux sites before, anyone can help support him on patreon if they really want.

People keep missing this -- SteamVR can be used from OpenGL. It's just very slow for the time being, probably due to a fairly dirty and unoptimized first pass at transferring framebuffer data out of an OGL context into the compositor's Vulkan context; they'll be bringing it up to speed over time. This could be in OGL and he's just dealing with the performance hit for now.

I probably should watch the video before I post, eh?
