R_fastzreject '-1' // If set to 1 activates a fast z-setting algorithm which takes advantage of hardware fast z reject for improved performance. -Ĭl_new_impact_effects '0' // Decresases rendered bullet impact effects Many users report performance increases on multi-core systems when setting this variable to a value of 2. A value of -1 uses the default for your system, a value of 0 uses synchronous single thread, 1 uses queued single threaded mode, and value of 2 uses multi-threaded mode. +mat_queue_mode - This setting determines the threading mode the material system uses. +mat_hdr_level 0 - Adjusts High Dynamic Range lighting effects threads - Put the number of threads that you have in your CPU, you can see it in the task manager under the CPU section
