Question / Help Huge Ping Spikes. Help please.

[livetobeevil]

I finally fixed my settings and able to stream on even 1080p, but to reduce some ping I rescale to 720p. after about 20minutes or so my ping SPIKES to 500+ ping and stays there for a few minutes. This is not good when I am playing league because 20minutes in with lag is crucial.
