L4S provides ultra low latency benefits to gamers.
Your ISP, router/gateway, and Windows setting which I'll cover all have to support it too. L4S is especially good to those playing Valve games such as Counterstrike while on Xfinity/Comcast.
Beta-grade L4S test website is now online to test if your connection is L4S ready! The idea is if you are in the trial it will work, if you are not it will not. I'm NOT in the trial & Comcast said they're not accepting new trial members. This test failed for me three weeks ago. I just upgraded from 1.2Gbps to 2Gbps yesterday and this test is showing success here! In windows you need to enable ECN Capability for this capability to work on your gaming computer! The steps to do so will be on the next reply.
Click "Do a test" and after a few seconds it will tell you if your connection is or is not L4S ready.

My understanding is Xfinity began the L4S trials starting summer of 2023 in select areas with partners Valve & Nvidia to push ultra low latency designed for realtime applications & enhanced gaming. The goal is to have extremely stable ping times with less latency spikes. Xfinity is pushing to have this available across the country in the 2nd half of 2024. The person I spoke with said L4S was currently targeted for a release before this summers end without an exact date.
The technical slide explains how it uses ECN headers to function. It's a dual queue system to provide ultra low latency. Geforce NOW will be more compliant before Valve products at the moment. Some quotes from their march 2024 slides, sorry I cant link them right now:
"imp us lld results = over 50% lag reduction"
"geforce now lag spikes are around 20ms vs 225ms! Significantly lower jitter resulting in cloud gaming truly viable. Valve/Steam Counterstrike results - down to roughly idle ping times! Preparing to operationally scale to millions of users."
(when they say idle ping times, under load ping times can fluxuate & ping spikes can occur. When testing Vavle's Counterstrike game the spikes were almost non-existent under this new technology!) | |

Xfinity/Comcast Cable Internet
XB8 box you rent from them is ECN Capable, pretty sure xb6/xb7 are too
This L4S is part of the IETF standard that affects the whole internet and not just Comcast. Service providers also need to support L4S and routers/gateways need to support ECN too.
Checking your setting inside Microsoft Windows to see if ECN Capability is enabled for upcoming gaming L4S features. Even better if you play Valve games such as counterstrike (hmm, maybe TFC too?)
1. Open "Command Prompt" in Win 10/11.
2. Copy & paste this into the command prompt. If you right click on the command prompt that will paste it.
To check what your current settings are only enter this into the command prompt:
netsh int tcp show global
Look for the line that says "ECN Capability" and take note if your gaming Windows PC has this set to enabled or disabled. The command above does not change anything, it only shows you your current settings.
By default on my win10 & win11 computers the ECN setting was disabled! The xfinity rented modem/gateway boxes are ECN capable.
3. If ECN Capability was disabled, enter this command below into the command prompt to change your windows ECN setting to Enabled:
netsh int tcp set global ecncapability=enabled | |

Great stuff, Snips. What is your background? Are you so knowledgeable about network and graphics from gaming? Or do you do this professionally? | |

Yeah mostly just gaming & having a strong ambition for tweaking my computer and learning. Like I don't think I know that much about this stuff but had a good laugh when the last two xfinity technicians came out to my house & I was stumping them with my questions, lmao. Made a friend with someone higher up there lastyear and had some great chats with him. One tech didn't even know what a network switch was, and that made me scared to death to let him do any work on my line, I watched over him the whole time, lol.
I'm thinking about creating a windows 10/11 tweaking website at some point but am overwhelmed at the amount of content I'd have to put together along with screenshots of settings. I don't like just hearing a tweak works, I want to execute tests & find proof of what something does along with a "feel" of if it was something major, minor or placebo. There are so many large tweaks to alter Windows from a slow workstation into a realtime ultra responsive gaming system. Like why the fuck did Microsoft change the tcpip congestion from CTCP to CUBIC a year or two ago? Lots of stupid shit Microsoft changes over time that are bad for gamers.
It's kind of crazy that xfinity/comcast customers are best off renting an xb7 or xb8 gateway/modem instead of buying your own, because with a mid-split you'll get 200Mbps upload on theirs instead of 30-100Mbps with your own. Anxious for the XB10 to come out later this year to hear about the specs more. | |
