A downloadable game for Windows

This is a very simple First Person Shooter game that allows you to simulate any given amount of milliseconds of input lag, as well as framerate caps. It can be used to get a general idea of what it would be like to play streamed games with a certain latency, for example

We have yet to know what the typical network latencies will be like for game streaming platforms, but around 80-120ms would be a good initial guess. So you can start by entering 100 in the "InputLagMs" field and see the difference it makes.

Note: "InputLagMs" is meant to represent only the network latencies. By default, you will still experience regular hardware/display/game code latencies even if the lag milliseconds is set to 0.


  • Press Escape key to toggle mouse cursor activation and game controls activation
  • With mouse cursor activated click on the input fields in the top left to set desired input lag milliseconds value and framerate cap value (0 is unlocked framerate)
  • Press enter to make sure the value you entered is applied
  • When values are set, press Escape again to return to game
  • During the game you can shoot at the red spheres


  • WSAD / LeftStick : move
  • Mouse / RightStick : look
  • Space / BottomButton: jump
  • LeftMouseClick / RightBumper : shoot
  • Escape: toggle cursor activation

it'd be awesome if there was a motion blur toggle button - I feel like motion blur absolutely kills any responsiveness

This very handy app would benefit a LOT from an updated version with an "invert Y" mouse input toggle... Couldn't really test thoroughly without it, non-inverted and my cerebellum don't mix and I bet it's the same with a lot of older players who learned inverted.
