Oculus has opened latency tester pre-orders for its virtual reality headset.
The tech allows developers to measure motion-to-photons latency from any point in the game development pipeline.
The firm said it had been able to reduce latency in all demos and integrations for the Oculus Rift, as well as identify potential rendering improvements.
It can also be used to test a development setup for optimal latency testing to help minimise it.
Only a limited number of latency testers have been manufactured, but Oculus said it would make more based on demand.
