Why didn't you just kick him Sammy. In theory I understand but I still can't make technical sense of how it would make them teleport around.
/com_maxFPS 250 - this was decided to be fair value for FPS and running a smooth game
/cl_maxpackets 100 - all modern PCs can handle the high packet rate, this ensures you're sending all the data, that your game can send, to the server
/cg_fov 80 - with UHD and QHD monitors you should really use this
/snaps 30 - send more bitmaps to the server
Ten years ago you needed to tinker around with undesired graphics effects to get smoother game in multiplayer and singleplayer, modern GPUs can give you 250+ without any need for turning down graphics settings. I have a GTX 1070Ti and ever since I got this, the above four are all I need to do, everything else is max.
@dadda2 when they made this game, there were many things they overlooked at the time. To run it smoother you had to do "stuff". They fixed those shortcomings one by one in later franchise releases. PunkBuster used to weed out the intentional offenders, who meant to exploit FPS, or graphics settings for seeking unfair advantage. I think what Sammy has done with resetting the graphics on each round levels the field though who mean to play unfair will have keybinds to get around it.
