It seems like Overwatch kills my internet performance.
This only started happening within the last 2 days. I thought it was my modem or Comcast but as I waited for them to schedule someone to come out, I noticed this only happened when I played Overwatch.
When I play OW, everything is perfectly smooth, fast, etc, even once I start a game, as I play it gets progressively choppier, both FPS and audio. When I check my internet at this time, its gone from a normal 400+Mbps to between 8-12-30 stuff like that.
The in-game stats still show high FPS, good MS etc as well.
Once out of a game check my internet and its still 8-12-30 Mbps-ish, but then after from seconds to a minute it will go back to normal 400+Mbps and stay there.
Ping tests to blizzard also actually are fine the entire time. Network and other resources for OW seem normal/low during this issue as well.
I have tried to disable my WIFI and unplug everything but my PC and it still happens so I don’t think its a device or anything else, it really seems to coincide only with OW.
I tried to move my Overwatch folder from my SSD on C to a M2 drive to another SSD and nothing helped. I did a rebuild/repair from my Battle-net client and that didn’t help either.
I’ve opened/forwarded all the Battle-net and OW ports on my Win10 firewall and on my Modem/Router.
I’ve tried closing all Apps like Razer or Corair or Nvidia experience, all that turned off and it still happens.
I have no idea where to look next, and advice?
