Left4Dead2 Visuals Multihack

On all maps, the game freezes for 2 seconds unconditionally from chapter 2. Chapter 1 does not freeze.

Its only on start, isnt it? After that its rare to lag again no?
I think i know what you talking about, if so, i have no idea what causes it, but i will try check it soon

And.. its a big deal for you? Or not?

It might depend on what you have activated, I don't have issues on any of the maps in terms of lag unless someones DDoSing
