2 games running it wouldnt let me aim properly,both times in bottom left pocket-only had a tap in black,literally a centimetre from pocket but wouldnt let me pot it,it cost me the game too

your computer was processing too much information at the one time.

try running less programs / processes whilst playing.

another tip i read before was to restart your computer before playing so that your computer has minimal processes running in the backround from previous programs you have used.

Also, open the arrow in the bottom right of the screen, by the icons. Check there's no unwanted programs running.

try game booster from google, it cuts out the processes you dont need running so it wont lag as much.

thanks lads
