That’s weird man. Shouldn’t fluctuate that much. Nothing eating up your speed right? Also, wired direct or using a power line adapter?
My games usually go as follows and I can tell a little about what to expect by my ping:
I usually get between 5 and 16 ping on the closest server
Most common connection is 22 - 28
Then 29 - 36
Then 42 - 60
Anything higher than that is usually only 61 - 68 but then I know I’m in no man’s land on a faraway server. Things get… weird.
The only time I fluctuate higher than that is if I alt-tab out or if something is eating bandwidth in the background. (forget to close download or something) but it immediately drops back to whatever ‘the norm’ is for that server when I correct it.
I’m only on a 300mb/s connection and speedtest shows a pretty steady 388 or so for the most part. I’m wired direct with new cat 6/coax.
