Pulse updates understanding

Hello everybody,


Please help me to understand the pulse updates algorithm. How pulse updates work in this situation:

I start to play in a full screen game on my PC and it takes 2 hours. AFAIK from NIS help, NIS does not start any updates at this time. What will I get with pulse updates when game is closed? Will I get all pulse updates for the last 2 hours or only pulse updates for the last 5-15 minutes?

 

Thanks in advance
