Basemark is finally putting its VRTrek latency tool to work. After months of delays getting the VRScore VR benchmark tool out to the public, Basemark released a software development kit called VRTrek Library for developers and hardware vendors.
Basemark first revealed the VRTrek latency testing hardware in March alongside its announcement about the VRScore benchmark. At the time, Basemark intended to release VRScore in June, but things don’t always go as planned. The company is still working towards bringing the benchmark suite to the public, but it’s ready to get the tools into the hands of creators to help them improve the user experience of their software and hardware.
Basemark’s VRTrek latency testing tool features two photodiodes that detect light from the HMDs display. The two sensors are spread out such that each one monitors a separate lens. The VRTrek hardware sends a signal to the computer via a PC audio jack. Basemark said it tested the tool with RealTek integrated audio cards. Your mileage may vary with other audio devices.
VRTrek Library provides developers and hardware vendors with the tools necessary to measure the time it takes for an image to reach the display following a draw call (in milliseconds). VRTrek can also measure dropped frames, duplicate frames, and screen persistence. VRTrek Library includes Basemark’s patent pending latency measurement device, VRTrek, which measures the left and right latency simultaneously. It also includes a software development kit (SDK) to allow developers to “easily integrate [VRTrek] into their testing frameworks.”
Basemark’s VRTrek Library latency measurement solution is available now to qualified vendors. To purchase a copy, contact firstname.lastname@example.org
