Build and Shoot

idk i used these 2 methods and i played with openspades, then openspades lag totally improved so try to set your pc to this settings when you have some lag during you play os or other games in your pc.

So you are using a laptop? If so, I understand why OS is running like crap. I use a windows 7 laptop and what I do for 0.0.11 I bump down Anti-aliasing, post process stuff, particles, shading etc. But I can only play on pinpoint or any other maps that have a lot of water in it. So try bumping down those stuff.
