BlackOps Tweaks

Call of Duty: Black Ops tweaks and fixes

Game won't launch. Steam repeats "Performing first time setup..." procedure.
Manually download and install the latest DirectX End-User Runtime.

I have my clan tag set on Steam, but the brackets are removed in game.
Remove your clan tag from your Steam name. Then in config_mp.cfg (Steam\steamapps\common\call of duty black ops\players) alter seta clanName "clantag" to match your clan tag - it will put it in square brackets.

How can I improve my hit registration and general network performance?
cl_maxpackets 100
snaps 30

How can I remove the cap/limit on my maximum FPS?
com_maxfps 120

When trying to install off disc it gets hung up on "steam setup" then says "failed to run install script"
If you are on Windows XP; Start > Run > "C:\Program Files\steam\steam.exe -install E"
On Windows 7; Windows key + R "C:\Program Files (x86)\steam\steam.exe -install E"
If "E" is not your CD-ROM drive, change it!

If your PC supports multi-threading:
seta r_multithreaded_device "1"
in config_mp.cfg (Steam\steamapps\common\call of duty black ops\players)

How do I improve the game's sound quality?
You can change sound to CD mode: 16 bits 44000 hz CD via control panel sound setting.

Misc. "potential" performance tweaks:
Run Steam in Offline mode > Start Black Ops > End the steam.exe process > Set BO process priority to high
/r_multiGpu - should be set to "0" if you do not have a multi-gpu graphics card.
/r_blur_allowed - people are reporting minor frame boosts with this set to "0"
/r_distortion - people are reporting minor frame boosts with this set to "0"
/r_dof_enable - people are reporting minor frame boosts with depth of field set to "0"
/r_glow_allowed - people are reporting huge frame boosts with this set to "0"
/cg_brass - people are reporting minor frame boosts with depth of field set to "0"
/r_cachemodellighting "1" - people are reporting minor frame boosts with depth of field set to "1"
/r_cacheSmodellighting "1" - people are reporting minor frame boosts with depth of field set to "1"

Nice one, Lee! Has anyone tried the cl_maxpackets 100 and if so does it work?
