Call of Duty: Ghosts PC Optimizations

Steam user Infinity7 has compiled a useful list of what to optimize Call of Duty: Ghosts on PC and you can find the recommended settings below. 

Infinity7 says the forums will be updated as necessary so it's worth checking back from time to time.

The game's config file can be accessed and some things can be modified to speed up the performance of multiplayer. It is at "C:\Program Files (x86)\Steam\SteamApps\common\Call of Duty Ghosts\players2\config_mp.cfg"

• seta cg_chatTime "18000" Default is "1200". Time chat stays on screen before disappearing.
• seta cl_maxPing "150" Default is 800. To ensure you find a good-ping server.

Call of Duty: Ghosts hasn't been received too well by critics with our own review giving the game 6/10 nevertheless Activision sold $1 billion worth of copies to retailers in the first 24 hours although it's unclear how many of those copies were then sold to players.
