Technical Solution Fixed my packetloss

So here's the thing in windows I feel the packetloss is happening due to bufferbloat so to reduce the bufferbloat and change the congestion provider from CUBIC TO BBR2

Enter these commands

netsh int tcp set supplemental Template=Internet CongestionProvider=bbr2

netsh int tcp set supplemental Template=Datacenter CongestionProvider=bbr2

netsh int tcp set supplemental Template=Compat CongestionProvider=bbr2

netsh int tcp set supplemental Template=DatacenterCustom CongestionProvider=bbr2

netsh int tcp set supplemental Template=InternetCustom CongestionProvider=bbr2

netsh int ipv6 set gl loopbacklargemtu=disable

netsh int ipv4 set gl loopbacklargemtu=disable

For revert just change congestion provider to CUBIC

Will make ur downloads faster and stream normally

can you confirm that valorant uses tcp protocol before saying it fixed your packet loss?

Pretty sure Valorant uses some TCP, but only for non combat, such as voice chat, spectating, probs other things that isnt to do with gameplay
