Quake II RTX in VR with Holochip

Holochip has been developing the ability to incorporate advanced Vulkan rendering capabilities into OpenXR projects to support light field and other next generation displays. This year at SIGGRAPH 2023 as part of the Birds of a Feather program, Holochip demonstrated that Vulkan ray tracing has been integrated with OpenXR and enables users with different types of displays (VR headset, and a light field display) both rendered using OpenXR, to play against one another in Quake II RTX.
