You may encounter noticeable delays when it comes to pressing the buttons on your controller and seeing the corresponding action appear on the screen in Mortal Kombat 1. To see how you can reduce the input lag for this reboot, you can take a look at this article from Seeking Tech.
1. To start off, we recommend playing the game with a controller or fighting stick through a wired connection. A wireless connection is slower and, therefore, leads to more input latency.
If you are playing MK1 with the DualSense controller on PlayStation 5, then you should plug the controller into USB port of the console and then go to the PS5’s Settings menu. From there, select Accessories > Controller (General) > Communication Method > Use USB Cable.
2. If you decide to stick with a wireless connection, then you should make sure that there is enough battery life remaining as a low charge could lead to the inputs becoming more unresponsive.
You should also make sure that the gamepad has a direct line of sight to the PC or console. Furthermore, avoid turning on other wireless devices near your play area if possible.
3. You should also check the settings of your television screen or monitor.
Make sure that you have the Game Mode picture setting enabled if you haven’t done so already as it will reduce the input delay. You should also avoid turning on any A.I. picture settings, like frame interpolation, as these may add to the latency.
4. In Mortal Kombat 1, you should also make sure that you go to Settings > Kontrols > Input Window Timing. Afterwards, make sure that this setting is set to Long.
By doing so, the game will extend the amount of time it will allocate to recognizing your inputs when it comes to activating special moves. This should be helpful if the latency is messing up your timing.
5. If you haven’t done so already, make sure you have the latest patch downloaded and installed for MK1.
An updated version of the game may fix any of the input lag issues you may be encountering in the fighting game.
