The NVIDIA Latency Display Analysis Tool (LDAT) is a tool that can be used to measure the end-to-end system latency of a PC gaming setup.
The end to end system latency is the time between user input, such as a mouse click, and the resulting light output from the display for a specific video game that is played on a full PC setup. This includes latency added by input devices, video source device (a PC), transport interface, and sink device(s). It is the entire “input lag” of a complete gaming setup.
Because this website is focused on measuring properties specific to the sink device, I will not provide a detailed review of this tool, but it looks like an effective tool in capturing the benefits of higher refresh rates in PC systems.
