Nobody seems to even to know why you want 250 fps. Lol this made me laugh so hard.
At 125 fps and 250 fps you jump differently. You set commands to switch in between them to do a special kind of jump called bounce jumping. One allows you to jump further and one allows you to jump higher. Really skilled cod players know all about this because it allows you to get in tactical positions and over certain obstacles faster for high speed map routing. So if you're a serious cod player not getting 250 fps is a bit of a problem. Don't talk about what the eye can and not see. It doesn't matter the fps effects the jump ability of the game. Also anyone who has ever played cod 4 for an hour can drastically notice a difference between 60 fps and 125 fps and it tends to effect your game play. Also some like to play on 250 fps just standard because they play better overall with it. But when it comes down to it 125 fps is the golden standard for cod 4 and if you don't know that you are most likely high level cod player.
