My friends see things differently...
When my friends are watching me play they say my crosshair is shaking most of the time but on my screen it doesn't shake and I don't shake my mouse to make my crosshair tremble.
I downloaded a demo of myself playing CSGO and I noticed that on the demo my crosshair really does shake and I also noticed that from time to time while I am walking there is like a small stutter as if I am skipping a frame which I myself never experience while I am playing and I also noticed that some things don't look at all like what I did on my side. I uploaded parts of the demo to youtube so you can see what I mean.
For example: In the demo a lot of the time when shooting my crosshair seems to be never be where I remember placing it while playing and when me and an enemy shoot each other the fight is always 2-3 seconds longer for me. On my friend's screens and the demo I die but on my screen when I am playing I am still moving and shooting and the time between where I die according to the server and my friends and where I die according to my screen isn't short at all. For example: At 1:48 of the youtube video me and one teammate die when we line up and the enemy gets a double kill. On my screen I ducked behind my teammate and kept shooting through my teammate for about 3 seconds but on the demo from the server I die much sooner before I even start trying to teamkill my teammate and kill the enemy at the same time.
