Too much Fps Spikes after Alt Tabbing out and in of the game

Dont know why but no matter what, each time i alt out of the game to check discord or whatever, when i open the game back and i unpause it, my fps drops to 3 for 5 seconds of something (all of this tested on zombies mode)

@venuzzz there are options in the video settings of the game.
Alternatively you can do this

Go in the bootstrapper command prompt (the console opened when you start the game)
and paste this (right click) r_fullscreen 0;r_noborder 1;vid_ypos 0;vid_xpos 0;vid_restart then press Enter

You don't need a third party app
