loic urself then ur good to go
LOIC (Low Orbit Ion Cannon) is a Dos program (denial of service) that is meant to take down super weak connections. Skids tend to use this to try to hit others offline thinking they are L33T. Dos shouldn't be confused with a DDos attack, which is a DISTRIBUTED denial of service, coming from multiple computers/hosts.
Change your graphic card by Nvidia GTX 970 or 980 ^^
If you're still looking for a method, I have one I found by accident.
Basically, get the HLDJ soundboard on CS:GO.
It's really simple/easy to use and download, but it raises your ping up to about 110 - 140 ping.
What's funny is, this is the ping that I get normally...
