UDP Packet.Win10.RegistryLocation

[PCgamer]

Hey there. Was recently reading the Advanced Tweaks section and I came across the UDP Packet size section and decided to take a look in the registry (windows 10 latest as of Jan 18') and I didn't find the registry location listed on the Advanced Tweaks UDP section; HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters. Is this not used in Windows 10? Or has the location changed? Also, what does FastSendDatagramThreashold, & FastCopyReceiveThreshold do? Does it reduce latency? Does it benefit gaming? Do either the UDP or the Threshold settings help reduce latency, or increase granularity? Thanks!

Windows 10 does not use many of those registry settings. What is still being used is in the "Windows 10 TCP/IP Tweaks" article: https://www.speedguide.net/articles/...ip-tweaks-5077

For gaming, you can look at the "Gaming Tweaks" and the "LAN Tweaks" articles here: https://www.speedguide.net/articles.php?category=93
