Latency Measurement Device and Library

VRTrek Library provides a software development kit (SDK) to be used together with Basemark’s VRTrek latency measurement device

Evaluate latency from the point of application frame submit to the point when the frame appears on given display


Accurately measure app latency, display latency, dropped frames, duplicate frames

Uniquely measures latency of both left and the right eye at the same time

Compatible with Rift, Vive, OSVR and more

“We are very excited to finally receive a robust tool for measuring latency in the form of Basemark’s VRScore and VRTrek. This enables the industry to set standards and achieve ever better functioning VR systems.”
- Jon Peddie, President and founder of Jon Peddie Research
