Just sharing something I found and hopefully it helps some people with lower spec PCs.

Recently i found that my card was trying to stream games to a nvidia shield even though i dont own one and it was eating at my cpu and destroying my framerate in games however i found a way to close down this process.

click the windows icon in the bottom left and search "services" http://i.imgur.com/NF1TAXr.png Next open up services and locate "NVIDIA Streamer Service" http://i.imgur.com/JQQmRVr.png Open the service and stop the service if its running then disable the service. http://i.imgur.com/lNvZSyg.png Do all this and hit apply and you'll be able to see a noticable framerate boost and drop in your cpu usage!

i hope this help a couple people out!
