Abstract
Computers for supporting multiple virtual reality (VR) display devices and related methods are described herein. An example computer includes a graphics processing unit (GPU) to render frames for a first VR display device and a second VR display device, a memory to store frames rendered by the GPU for the first VR display device and the second VR display device, and a vertical synchronization (VSYNC) scheduler to transmit alternating first and second VSYNC signals to the GPU such that a time period between each of the first or second VSYNC signals and a subsequent one of the first or second VSYNC signals is substantially the same. The GPU is to, based on the first and second VSYNC signals, alternate between rendering a frame for the first VR display device and a frame for the second VR display device.
