• r_vsync

VSync helps in preventing screen scratching. Most of the users do not notice the change and if you are one of them then I would simply suggest you to set VSync to ‘0’ since you will not see a major change in your game play. Vsync do not have any negative performance with the graphic cards. But there are some are some major issue which are associated with the Vsync with the current release of the Black Ops. Simply set it to “0”.

• r_multithreaded_device

This is a very important settings which must be enabled on your system since this is the minimum requirements of the Black Ops this evidently indicates that you require a Multicore CPU if you want to run this game without any performance issue. I have noticed a major change after setting this to “0”. However I would advise you to change this setting only if all other settings fail.

• r_multiGpu

Enable this setting ony when you are having either more than one graphic card or a graphic card with multiple GPU’s. If you are not aware of Multiple GPU’s then simply set this to “0”.

• r_blur_allowed

This will help you to enable the Blur shader effects . This setting will be negligible if you are using a strong shader card. Or simply you can set this to “0”.

• r_distortion

This setting will help you to enable the shader effects if you are having a shader card which is strong enough then this setting is negligible. Or simply you can set this to “0”.

• r_dof_enable

This setting will help you to enable the Depth of Field shader effects. if you are having a shader card which is strong enough then this setting is negligible. Or simply you can set this to “0”.

• r_glow_allowed

This setting will help you to enable the Glow (HDR) shader effects. if you are having a shader card which is strong enough then this setting will have a negligible impact on performance.I think that this setting is a bug but I noticed a major performance enhance after setting this to “0”.

• rate

This is the rate through which a client sends a packet to the server. Setting this very low somewhere below 10000 will definitely worsen the performance since you are not sending sufficient data to the server and hence you should set this above 10000 preferably 50000+ . But cross check this with 20000, 30000 and 40000 since this totally depends on the speed of your server. This setting should be changed as per the connection speed and it will require some fine tuning.

• cl_maxpackets

This setting helps you to control the number of packets that your client will receive through packet transmission. If the setting is somewhere below 25 then I think that there is a major threat of being disconnected more frequently. Do not set this too high that is above 150 this will also affect the performance. This is quiet hard to tune but try with a series of values you will find that the setting somewhere near 100 will help you improve the performance of your game.

• More technical information:

At the outset poor CPU management is the major issue which is causing this lag. Most probably what appear thread context switching. Your system hangs during the gameplay since data is switched between the cores of the CPU occasionally. Even the poor management of the netcode is also one of the major reason behind this lag. This netcode must be shared with the game engine so that if the CPU hangs then data should stop transmitting between the server and the client machines. This will fix the lag on your computer. This will fix the lag on your computer and will help you to ease the load for everybody else on the server of the game so that you all get a quality game play without any lag or issue.
