How to reduce the "lag compensation" MW3 adds to your client!

by absol89 (Steam Forums)

 

Straight from user Infinity7 in the game optimizations summary-thread (Click Here to view)! He works with IW and has provided many solutions. The most important are listed in this thread!

 

The MW3 engine tries to balance the matches by adding lag to people with high-performance computers and connections - which means: if you have high FPS and GPU usage and low ping or host, the game will see this as an advantage and add latency to your client. This means that the more GPU usage you have - the more time advantage your enemies will have over you!

 

To fix this and make the hit detection spot on, with high fps and low amount of added lag compensation you need to reduce your GPU usage by limiting some of the variables in the config_mp.cfg

 

In game - set your resolution to whatever your monitor is and antialiasing to 2x, shadows and depth of field and soften smoke edges to OFF, ambient occlusion to off, image quality to native and textures to high to prevent streaming

 

Now close the game and go to your config_mp.cfg and change these

 

seta cl_packetdup "0" - makes hit detection more spot on

seta r_depthPrepass "All" - replaces depth of field with a less GPU hungry variant

seta r_distortion "0" - removes distortion from muzzle flash and fire and explosions

seta r_preloadShaders "1" - reduces the performance hit by not loading shaders as you play

seta sm_maxLights "0" - stops using gunfire and explosions as light source for shadows

seta r_texFilterAnisoMax "2" - better look than 4 (default) and less GPU usage

seta r_texFilterAnisoMin "2" - better look than 4 (default) and less GPU usage

seta snd_enableEq "0" - stops the game from making additional sound processing

 

Try using these and it will feel like you are playing on a dedicated server again!

 

It also helps to set the iw5mp.exe priority to low in task manager!

 

====================================================================================

 

For those noobs who play console version Here's another fix. This might work for PC platform as well, but I haven't tried it for PC so I'm not sure, but it does make a difference on Xbox Live and will probably work for PSN users as well.

 

To view what he's looking at in the video just type in your IP address in your web browser (in the website address box) and login to your ISP account or use your network setup wizard/program if you have one.

I made the changes. I actually like the graphics better now. I played about 5 games and noticed no lag issues. It seemed like every time that I was hitting someone - they dropped. I will be keeping these changes. Thanks.
