MiSTer Laggy is a lag testing device developed by Martin Donlon, also known as WickerWaka, a renowned MiSTer developer with many notable contributions to the MiSTer project, including creating the impressive Irem M72 arcade core. His latest MiSTer project is a hardware addon coupled with the new MiSTerLaggy core which is downloaded when you update your MiSTer FPGA and located in the Utility folder, using the MiSTer Laggy enables you to assess the lag or latency on your display devices.
Setting up the MiSTer Laggy is easy just connect it using a USB type A to type C cable. Plug the type A end directly into the User IO port on the MiSTer, and insert the type C end into the USB C socket on MiSTer Laggy.
Next boot up the MiSTerLaggy core from inside the Utility folder from the MiSTer main menu. The core operates by displaying a test pattern on the screen and gauging the time it takes for the sensor to detect this pattern. The resulting latency is displayed at the centre of the screen, accompanied by average, minimum, and maximum measurements in milliseconds. The test pattern comprises of three white flashing rectangle sections where the sensor can be positioned, allowing for latency measurement at the top, middle, and bottom of the screen.
More information and setup instructions are available on the GitHub for the project.
If you have a MiSTer FPGA then this addon is an excellent low cost combined hardware and software solution capable of accurately measuring the lag on your displays.
