Hi, im sublimezm and i play on your server

Sublime... maybe this will help you (it helped me!) The norm and fast settings seem to work best for me on our server

Taken from the Steampowered support forum:

Steam Rate
The first thing you need to check is your Steam rate setting in the Steam > Settings > Internet > Internet Connection Speed.

Make sure that is set properly for your connection type, too fast or too slow can cause problems.

In-Game Rate
Basically the default rates are fine for most connection, servers typically prevent any changes to those settings. Most players get good performance from:

rate 7500
cl_updaterate 20
cl_cmdrate 30

Test Script
You are welcome to try this test rate settings script to see what what different settings are like, but in general the normal ones work very well for internet.

Try a couple of settings and see what gives you the best performance with the least choke and loss:

Cut and paste these (fix any linewraps) into your "userconfig.cfg" file (create one if you don't have it) or just get this rate.cfg file, put it in your game folder and add the line "exec rate.cfg" in your userconfig.cfg file.

This script uses the F2 key, but also has console command-line names for each speed setting.

56K modems are typically "rate" 3500 to 5000 max, you may need to edit some of the rate settings.

So the direct commands are:
======================
dslow - only useful for minimal testing, probably not playable
vslow
slow
norm - pretty much default settings
fast
vfast
Lfast - Lan and high-speed connections only

rates - see all the current settings
or hit the F2 key to cycle around to all the settings
