Launching any steam game instantly kills my internet
I noticed that when I launch any steam game it kills my internet. I use a wired connection (ethernet) and get consistently 90-100mbps download and 90-100mbps upload speed.

However whenever I launch any game on steam it instantly lowers my internet speed to under 5mbps download and 1mbps upload.

Even stranger though, launching other games not on steam such as apex legends or Fortnite doesnt hurt my internet nearly as much and leaves me at about 80-90mbps download and 80-90mbps upload. this leads me to believe its an issue with steam.

ive already changed my DNS and and Ive already lowered my in-game server browser max ping to its lowest value (250). neither of these fixes have worked for me.

if anyone has any better or more helpful ideas id be very appreciative

Go to settings -> Downloads and unselect the option to limit download speed during games.
The option is meant to guarantee smooth streaming if needed.

Network problems can be tricky, there are so many variables at play that its hard to diagnose an issue without actually being sat at the PC concerned.
You could have a look at your routers QOS settings, (Quality of Service) and its priority settings for each device/protocol on your network to see if anything looks amiss.
Heres an example for a netgear router, (yours may differ):-

Failing that,
I`d open a resource monitor screen on your PC and watch the network traffic to see if steam (or something else), is hogging the bandwidth somehow.
(open task manager, open performance tab and you`ll see a link near the bottom for the resource monitor).
Running a good anti-virus and malware scan would also be a good idea.
You could also try resetting your network adapter.

Sorry if this isn`t much help, but its a place to start.

Disable downloading games during game play may also be effecting it could be using your PC resources.
Steam Settings Downloads on right.Allow Downloads during Gameplay.
