Hi,

This is a mod that tries to reduce lag by automatically modifying your DeltaTime depending on the speed of the game.

To use it deploy the grenade called "DeltaNade" of the "DeltaTime" faction.
(It will instantly dissapear when you throw it, that's ok.)

I hope this helps, however you should know that modifying DeltaTime may cause some mods to behave oddly depending on how their lua was written.
Edit: You shouldn't have problems with my mods, except for dissapearing laser sights.
If this happens you can restore the default value of DeltaTime by pressing ctrl+p and then by using the keys written near "DeltaTime"(default value if 16.6667 ms). If you deployed the deltanade you should restart the scene before doing so(ctrl+r).

You had very nice idea!
Oh and no need to editing .ini you can change delta time back to default in-game. Ctrl+P and there you will find key binds to do this.

Indeed that is easier to do, I modified the instructions in the original post.
