Problems with Lag

[Naso]

Lag in firefights, kind of unstoppable, get a better GPU & CPU? Speaking of GPUs what graphics card are you running and whens the last time you have updated the drivers? Also like everyone else said, try disabling your AV or uninstalling it for a moment if you cant. If you don't go anywhere suspicious you shouldn't get anything.

Anyways.

Most of the settings in those high fps configs are not really needed, you only need a few like these to really get a performance boost.

Autoexec

Steam\steamapps\steamloginname\counterstrike source\cstrike\cfg\autoexec.cfg

r_rootlod 2                    //Model Details Low

cl_ragdoll_fade_time 2    //Ragdolls disapear fast
r_waterforceexpensive 0    //Single reflections
mat_reducefillrate 1        //Low Shader details

launch Options

Also the thing that will prob get you the most boost Is in the game start up config.

Games > right click TF2 > Properties > Set launch Options...

-dxlevel 80 -heapsize <integer>

Note: -heapsize basically it uses the amount of ram you tell it too use. When using this tewak, it's recommended to use half your ram rather then all. The easiest way to get a rough estimate on how much ram you have.. would be going into the start menu, right clicking "My Computer" and going to Properties. Once you've found out how much ram you have in your system, multiply that number by 1024 and then divide that by 2.

So, if you have 1024mb of ram, you're heapsize should be: 524288.

Note2: You can take off -dxlevel 80 after you launch the game once with this on since it will always launch in dxlevel 80 unless you put a different one in the settings. If you leave It you wont be able to change your video settings.

Resolution

Setting your resolution lower can also help a lot since your video card doesn't have to render things so big, but If you feel that It doesn't make a difference In your system because of your CPU Is under powered or something, keep It medium low. I play at 800 x 600.

Should help out a bunch.
