Lag Issues - Any Ideas?

Alrite guys, just posting this for advice about my lag.
Recently i am lagging alot on servers, even UK 1's like SP.
My ping is fine, going from 30-50.
I do not normally feel myself lagging, but others do and i do feel my shots not regging - very annoying
I have good internet connection, not a "chinese dial up service" as Teddy says, and i have changedrates to what people have recommended.
Any ideas for how i can get rid of this?
Cheers,
Hawk

First of all, a high ping doesn't always mean your internet sucks.

There are several things that can cause your lag, I'll sum a few of those.


1. Wireless internet
Even a closed door can cause lag spikes. Although this probably doesn't
cause your problems, I would check for obstacles that might be
in the way of your wireless connection. If you don't have wireless, then
skip this step obviously.

SOLUTION: Check for obstacles

2. Processes
This is what I think will cause your lag. Try to check the processes your
PC is running. A virus scanner might start running while in-game, because
scanners often think you are not using the PC while the game is running.

SOLUTION: Run Gamebooster to close everything you don't need.

(Note: only install gamebooster, no other software :p)

3. Updates
Some updates of your hardware actualy exist to help you. Try to check if your
soundcard, graphcard, ... are up to date.

SOLUTION: check the sites of your hardware or use Gamebooster to help you.

4. Rates
Although you've said your rates are fine, I would double check it.

SOLUTION:
rate 25000 (or 30000/35000)
cl_cmdrate 66
cl_updaterate 66

5. Defrag
I don't know if you have problems with any other online games. If so, then
it'll probably be your PC. If not, there'll probably be something corrupt about
your CS:S.

SOLUTION:
Try to defrag your Counter Strike Source. You can do this with Steam, but also
with Gamebooster. I suggest you trust Steam on this.

If the problem still exist, I would simply clean your PC and run a complete
Hard Drive defrag after. Cleaning PC is possible manualy, but also with
a software called Ccleaner. Defrag is possible in windows itself. Right click
on your HD (C:) and pick "defrag" in the menu.


If the solutions above don't work, and it's a game related issue, I would simply reinstall the game
and check what it does. Good luck with it
