Open Source Latency Testing Tool - OSLTT

In short, OSLTT is my attempt at an open source latency testing tool - similar to NVIDIA’s LDAT. At launch, the tool is able to do the same custom DirectX test as OSRTT, mouse and keyboard latency testing, in game end to end latency testing, and audio latency testing. It is still in its early stages, so please be patient with me. I’m working on it as hard as my failing mind and body allows!

This guide is also a very early iteration. The video guide is much more complete, but I’ll aim to add more here too.

Main Features

  • Total system / click to photon / end to end latency measurement
  • On Display Latency
  • In game latency
  • Mouse click / keboard keypress latency
  • Audio latency
  • USB C connectivity
  • TRS Microphone jack AND INCLUDED MICROPHONE
  • 2 pin input for remote triggering
  • Built in status LED
  • Auto-updater for both the program and board firmware

Main Goals

  • Transparency - raw data saved so you can verify the results manually
  • Accuracy - the raw sensor data is accurate to 15us (0.015s) and the processing code has months worth of checks
  • Easy to use - I’ve tried to account for many issues and edge cases so for a typical display it should be plug and play. Includes USB supply stability checking, brightness calibration & processing.
