The Lag & Delay ur talking about may be caused if your not alone on ur internet connection , like example if u are on laptop and u use a wreless router on wich other can connect and steal internet from ur router that may result in U lagging while playing on internet , or if ur using a a router wich connects multiple PCs with LAN cables , if the other person(s) are connected to ur router too , and they are using the internet for Waching movies ,downloading , watching on YouTube , and the connection isn't that powerfull , u may experience LAG and Delay , if ur Alone on ur internet connection try disable Automatic Updates in Controll Panel , maybe ur PC is automatically downloading and installing updates and u don't know , or go to START BAR , see RUN and click it and in the box type services.msc , press ENTER than a window should appear find Background Intelligence Transfer (BIT) and disable it. Hope this will be usefull for u.
