Hi there,

for some time now I've come across an interesting issue with my personal pc and steam running on it.

In essence it keeps my max download speeds between 1.3 to 1.8 mb/s. Occasionally going as high as 4.5mb/s peak.

I have 500mbit/s connection, and before this issue occured I used to get up to 60mb/s.

This issue also only occurs in steam on this machine, if I use a different client like Uplay I get high downloads above 40mb/s.

I've narrowed it down to my current pc but I am at a loss why it could be. I will list the things I tried below, any additional help or advice is very welcome.

Thanks in advance!

List of already done troubleshooting:

turning it off and on again

deleteting steam download cache

change download servers

re-install steam

test steam on a different machin on the same network (it worked perfectly fine)

deactivating and later uninstalling my (ESET) antivirus and its firewall

testing different drives in my build, HDD, SATA SSD, NVMe SSD - no difference

restarting my router

restarting the network switch

flushing my dns cache

doing speedtests - 500mbit/s give or take

trying different download clients aside from steam - works all fine

probably more that I cannot remember at the moment
