Most games that are out use the Multicore Rendering option to allow more cores to run with the game and increase the FPS of the game. The original Insurgency has that very option, but this version does not. If you guys added in Multicore Rendering, it can definitely help out the FPS issues that everyone is having currently. It might take awhile to configure that sort of settings, but it will be worth the extra time to implement that setting into the game.
