We are LunarG, funded by Valve to improve SteamOS on Linux, the Vulkan API and SPIR-V. Ask us anything!
We are LunarG. Developers of Glassy Mesa and other driver based technologies. We were contracted by Valve a year ago to work on improving graphical performance on SteamOS by providing Linux expertise at the driver level. We have more recently been involved in their work on Vulkan API, GLAVE, SPIR-V and other tools for the new open source standard. Ask us pretty much anything (hint: we like technical questions) :)!
Edit You can check out the Vulkan trace file debugger GLAVE here: https://www.youtube.com/watch?v=miZmas6sGqM
Edit Alright guys, thanks so much for your questions! Time to get back to work ;)
