So you are saying in this fix that with cl_updaterate and cl_cmdrate should be those you are referring..
If you are getting flush entity packets..Reason simple is if you are using WLAN and it gets small drop spikes sometimes..
But if you have **** internet and getting flush_entity..I recommend you leave CS 1.6 alone and upgrade your internet..
If you have internet with 1mbs..Don't expect your CS will work fluently all the time..
One thing I am confused Drake..
If you are using those cvars what I know you are using..Why on earth you have 25000 rate.......Weird weird...
Do you know what the ones who's have best rates see you ingame.. You are dissappearing and moving like ghost to time to time...
And if you are playing:
Skype must be omg turned off.. ==> HIX!!!
Automatic updates must be stopped or service disabled..
Turn off your current firewall or antivirus or go silent mode...
Use advanced systemcare and turboboost..
Delete all files and folders : in run command: pretech and % temp%
If you really wanna get some information about tweaking or about CS 1.6 go..
www.satanion.dk and see their links..
PS. In to end if you have 1mbs internet......=> Try play tetris online..
