Input lag
Recently I came across a post on this site in which many people were arguing about whether fps affects input lag or not, now I want to ask:Why, when in cs go, I set a limit of 60 fps on my 60Hz monitor, input the lag was felt so strongly, and it was impossible to play than at 144-200+ fps, or even when I didn’t set the limit, there were just drawdowns, and the input lag was still felt, what’s the matter? Please explain how to remove this input lag at 60 fps?
Monitor matrix and features of its work. Google and research the topic. Even the numbers, according to the delays that they write in the description of the monitor, sometimes do not correspond to reality (does the frequency correspond to the vertical scan rate of the pixel change rate).
Spoiler 
Also, delays depend on the computer, your 144-200 are worth nothing, since this is an average, and rendering each frame (out of 144) takes time (this is a separate story of the minimum 0.1 / 1). Judging by the FPS, in principle, your computer is wildly weak (some kind of juanan with xeon 1240), because the 5600X produces around 500 frames, 12900k generally around 1000 frames. You can also go to the memory subsystem, the video card (although there is no graphics in this game, as unnecessary). And in the end, the gasket between the chair and the chair.
60 vs 144
On the net you can find a lot of information in principle. Do not write everything here. There are a lot of videos and articles on this topic. This topic is extensive. Well this video is so easy to note.
imput lag, as I understand it, when you pressed the run button and the character is running, you let go and he is still running or moving the mouse and the reaction to actions is also delayed. it is strongly curled what kind of games and what is going on there.
if it seems to you that the movement of everything that happens in the game without your participation is abruptly or slightly slows down, this is either some internal problems of the computer (but they usually should increase due to the processor if your PC can 140-200fps in games) or these are the features of the matrix and you need to look for settings on the monitor so that the reaction speed of the matrix decreases and fast objects become blurry and with trails. Then 30 fps is fine to play.
