The MiSTer Laggy is a display latency tester designed for use with the MiSTer FPGA system. Comprising of a dedicated core running on the MiSTer FPGA and the hardware sensor connected to the MiSTer’s User Port via a USB type A to type C cable.
MiSTer Laggy measures the time between when a frame is sent to the display device and when that frame is displayed, operating on a similar principle to the ‘Time Sleuth’ lag testing device, it utilises the MiSTer platform to generate the video signal and record measurements.
Display latency is of significant importance in retro gaming as OLED and LCD displays incorporate sophisticated video processing pipelines, potentially leading to elevated latency. Display manufacturers often do not provide informative latency metrics, and the performance of a specific display may fluctuate based on applied settings, as well as the input signal’s resolution and refresh rate.
Martin Donlon is the developer of this project, the project GitHub contains all the information on setup and basic operation.
The MiSTer Laggy hardware only functions with the respective MiSTer Laggy core located inside the Utility folder from the MiSTer main menu.
The MiSTer Laggy requires a MiSTer Analog IO board v6.1 or Digital IO board v1.2 and newer to function correctly. Additionally, this addon lag tester does support other IO board types providing they have a User IO port.
✅ Requires Analog IO v6.1 / Digital IO v1.2
✅ Optional 1 Meter USB 3.2 Type A to Type C Cable
✅ Fully Assembled & Tested
