Basemark’s VRScore is an interesting piece of software. VR performance evaluation tools are rare, and VRScore is a respectable attempt to fill that gap during this market's nascence. At the same time, VRScore's results can be a little bit arbitrary. That is to say if you base your buying decision solely on this benchmark's outcome, it would be hard to choose anything other than an Oculus Rift DK2.
VRScore appears to favor the difference between the raw framerate with and without an HMD, rather than the display resolution and refresh rate.
The fact that each HMD operates at its own target resolution is a point of contention, too. Because of the lower experience resolution, Oculus' Rift DK2 manages lower app-to-photon latency scores, which shouldn’t be possible. The DK2's 75Hz refresh rate shouldn’t be capable of outpacing a 90Hz low-persistence display, but because the Vive test taxes our GPUs more heavily, Oculus achieves a more attractive latency score. Even the Rift CV1, which has the same resolution and refresh rate displays as HTC's Vive, appears 1.5ms quicker than the Vive because the test runs at a lower resolution.
Nevertheless, VRScore is a welcome addition to the benchmarking scene, despite its curious results. Basemark normalizes the scores across the board, so we can effectively compare hardware configurations. The tool doesn't appear ideal for comparing HMDs to each other, but it should prove useful for evaluating the VR-readiness of specific hardware configurations. Most people won’t have access to more than one VR HMD (if any), so it shouldn’t be a surprise that Basemark puts VRScore's emphasis where it does.
We’ll surely explore the merits of VRScore with a larger array of hardware in the future. The tool may not help us determine which HMD offers the best display capabilities, but it could help us build a database of hardware best suited for different VR platforms.
