Examples described herein generally relate to rendering virtual reality images on a computer device including an integrated first graphics processing unit (GPU) and a discrete second GPU. The second GPU can receive first pose information of a head mounted display (HMD) connected to a video port associated with the first GPU. The second GPU can render a virtual reality source image from an application based on the first pose information. The computer device can transfer the virtual reality source image from the second GPU to the first GPU. The first GPU can receive second updated pose information of the HMD. The first GPU can adjust the virtual reality source image based on the second updated pose information. The computer device can display the adjusted virtual reality image on the HMD via the video port. The virtual reality source image may be divided into portions for pipelining among the GPUs.
