How can I troubleshoot Call of Duty 4 and how choppy it is?

Hi all,

I installed Call of Duty 4 and have been playing it very smoothly for quite sometime now. Today I started it up, and its really choppy...extremely choppy compared to yesterday. COD4 runs through steam. I have the following hardware:

2 GHz Dual Core Pentium
Asus P5B-E Motherboard
BFG GeForce 7950 GT OC 512MB GDDR3 PCI-Express Dual DVI/TVO
*I did not overclock these

I've done the following to troubleshoot this:

Updated my MB bios
Updated my chipset drivers
Updated my video card drivers
Went into msconfig and turned off all startup items
Killed specific tasks in task manager that weren't critical
Ran COD4 in safe mode (COD still ran a little choppy)
Turned the graphics as low as I could and it still ran choppy
Gone on different servers

When I play, it looks like I have about 1 frame per second and the sound repeats itself over and over

Could someone give me some sort of direction on this?

First do a clean boot and restart the computer

It seems it could be security software like norton or any other software at the startup that could be creating this problem.

If nothing else has changed I'd suspect your connection, perhaps your ISP is having problems.
Can you check your latency?  (Speedtest would be a useful guide

Do you have the same issue if you play COD offline?
As ded9 said, it could be security software that's running in the back like a virus scan.
If its not either the ISP or security software i'd recommend reinstalling COD as that might fix things aswell.

Goodluck :)

Thanks ded9,

That worked for the choppiness. It seemed that some service was taxing Call of Duty 4.

The only thing I noticed now is that I'm getting significantly low frames per second compared to before. I even lowered the graphics and texture, but its still really low. Does anyone have any suggestions?

I've already reinstalled COD4 and my video drivers...
Go into your config_mp file in the C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\players\profiles\profile name folder and make the follwoing changes. you will have to do a search for these settings. These will make your FPs go up -

seta cl_maxpackets "100"
seta com_maxfps "125"
seta cg_blood "0"
seta ai_corpseCount "1"
seta cg_brass "0"
seta cg_fov "80"
seta r_distortion "0"
seta r_drawSun "0"
seta r_drawWater "0"
seta r_fastsky "1"
seta r_preloadShaders "1"
seta r_rendererPreference "Shader model 2.0"
seta r_specular "0"
seta r_texFilterMipMode "Force Bilinear"

There are more settings but I found these gave me more FPS. I used these with my 7950 GT card with no problems and maintained a steady 125 fps throughout the game. Make sure to backup your profile before doing this.
