choke issues with no resolve!!!

[comradpoplin1]

Ok here is my bind, i have a pretty smooth running game until somthing happens lol!
i get average fps for my system 50-70fps and everything runs pretty wellbut as soon as the action heats up then i start getting choke issues the game jerks the even if a grenade goes off and i can hear it i dont need to see it and the choke kicks in in the netgraph display the choke jumps from 0 to 25 or so in a second then drops again its like if someone runs round the sorner the game jerks for a second as the fire fight starts then will go to normel again while the fire fight is still ensuing. as you can imagine its quite annoying i have set rates to default set them to my preferred settings wich are
rate 30000
cl_updaterate 100
cl_cmdrate 100
no diffrence either way
ive ran everything on default video settings and everything on low low settings and still no change ive had it running in dx7 dx8 and dx9 modes and no better in any

my specs are
athlon xp 2800+
512ddr
9600pro

ive updated all my drivers other than initiel contact the game runs fine the fact that a loud noise like a nade going off can cause the choke if i dont even see it go bang is wierd
any help is appreaciated thnx

Have you checked the sound settings? Do you have a good sound card or a good on-board sound chipset?

Have you checked for spyware and adware? Virus scan?

Some ATI cards are not performing very well with Source. Is yours one of them?

There are a number of tweak sites which can help you tweak your BIOS, Operating System, Video Card Settings and CS:S setting. http://www.tweakguides.com/ is one of them.

I hope this helps. Hope you get it sorted.
