With the current (nov 5th) 2.5 version, how long do smoke grenades last as well as the gas grenades? In the previous version of 2.5 I had from early Oct it was just through the aliens turn. My frame refresh rate drops way down when I use one. Any thing else I might do to increase the FPS as far as preferences as I'm sure it's mostly due to my laptop but I was wondering if there might be something I'm missing or something to try.
