3/31/2023 0 Comments Multilaser xpad js063The polling interval is measured in Hz and indicates how often a USB device is polled per second. On the MiSTer side only the lag caused by the USB polling can be reduced if the connected USB device supports a lower polling interval. The latter is outside the scope of MiSTer and can only be improved by using a better controller. In this case the overall input lag is the sum of the lag caused by the USB polling and the lag caused by the controller itself, how quickly it processes the signals. ![]() ![]() Input, which involves controllers, mouse, etc, Processing, which would involve buffering in the core, execution or delays in code and Display which involves the output of the video to your display device.įor a more detailed overview of lag and exploration of it, please refer to this page:įor input, MiSTer primarily uses USB. (Most players can adapt to lag that is consistent.) * Lag that isn't constant can be an issue on games that require precise movement. * If the latency is different between two players, it could introduce an unfair advantage. Lag is only problematic in a few specific cases: * Some older games were designed to rely on extremely quick response times (e.g. A frame is typically 16ms for a system using a 60 frames per second (60 Hz) display. Developer Reference Developer ReferenceĪ common concern among retro enthusiasts is whether a device of this sort has lag and whether it will create a less desirable experience compared to original hardware.Įvery electronic equipment exhibits some kind of latency, but it only becomes problematic if this latency causes frames to be missed. ![]()
