I'm trying to figure out what's causing my lag in games. Temps are fine, when I open my task manager nothing seems abnormal except this:

Is this normal? Or does it indicate a problem. My Ethernet chart has massive up and down spikes (as shown in the picture) but not sure what this means. Could this cause game lag/stuttering? Thank you.

The top of the chart in it's current position puts the spikes up to about 100kbps. That's like 2x 56k dial-up. It's not unusual what you're seeing.
