First Look: Basemark’s ‘VRScore’ Benchmark Arrives With a Unique Solution for Accurate Testing
The software itself is broken into three sections:
System Test: Purely a test of your PC’s rendering grunt, this runs the Crytek developed ‘Sky Harbor’ VR experience, itself running on the company’s CryEngine software, and measures the resulting frame rate throughout the experience. The benchmark is rendered in stereoscopic 3D and uses pre-baked head motions, presumably recorded from an in-house playtest, to simulate VR headset usage. Each frame from the experience is rendered sequentially as quickly as possible and that sequence run multiple times. The faster you complete the loop, the faster your PC is. This clearly does nothing to gauge performance in relation to your VR headset, for that you’ll need to move to the full test.
VRTrek Test: This is the more interesting of the two benchmark modes as it leverages Basemark’s unique selling point, the VRTrek sensor device. VRTrek tackles a difficult problem (measuring the latency between images being rendered at the PC and displayed on the VR headset) rather elegantly. This benchmark runs the same looped experience as the System Test above, but this time displayed through the headset, ready for latency measurement.
The VRTrek device contains two photosensitive sensors mounted on a height adjustable perspex stand. Tweak the height of the sensor for your VR headset and position them to sit in front of each lens. Then you simply attach the single audio cable to an enabled Mic 3.5mm jack on your PC’s sound card and you’re ready to go.
VR Experience Mode: Simply gives you the chance to try out the Sky Harbor benchmark experience for yourself and it is well worth doing so. Road to VR‘s Ben Lang was so impressed with VRScore‘s little demo after trying it at last year’s GDC, he remarked that Crytek had “accidentally made the most spectacular cinematic VR short I’ve ever seen”.
VRScore will be launching initially with its Corporate version, with both the Professional and Free versions following in Q2 2017. The differences between the editions are broken down on Basemark’s site here.
