Now, gamers will want to play on Linux for the low latency on online games.
Most low latency use cases in games use UDP, not TCP.
Unless it’s a Java Minecraft server which I believe exclusively uses TCP still.
Yeah, that would make sense as opening TCP connections is not really viable for low latency, hahaha.
Opening the connections is one thing but resends and stream ordering can also cause issues since they might delay the latest information reaching the user space application even if the packet for them has actually arrived just because some earlier packet has not. There can also be issues with implementations waiting for enough data to be available before sending a packet.
Depends. There was that one F2P COD clone which used TCP and IIRC it did fine?
If your connection is stable, the latency will more or less be the same, but TCP will consume more bandwidth because of acknowledgement packets, making it harder to keep your connection stable.
On an unstable connection, TCP latency will skyrocket as it resends packets, while UDP will just drop those packets unless the game engine has its own way of resending them. Most engines have that, but they only do it for data that is marked as “important”. For example using an item is important, but the position of your character probably isn’t, because it’ll be updated on the next tick anyway.
Online games don’t typically have many concurrent connections, though, do they? Just the one.
I’m not an expert, but I suppose as this patch is on the kernel and not on the game, this will still improve any connection your kernel needs to do, like sending telemetry of your anti-cheat engine and other apps that make TCP requests while you are playing online games.
Before that you have to download it. Well, using p2p mechanisms.
I always download my games before playing them. I don’t know what you mean here.
I think they mean peer to peer arrr
But is that related to my comment? I don’t understand why he’s talking about downloading games via P2P.
Arrrrr 😅😅😅
🤯
Unfortunately, many games where people care about that lower latency tend to be competitive with some kind of anti-cheat that doesn’t mesh with Linux.
Somebody please temper my expectations because this seems like an absolute game changer.
You’re not a cloud server that needs to run this many concurrent connections (probably)
Well I am, so that’s exciting
No but my friend is cloud server with many concurrent connections and may want to hear the good news!
The test data on article is about server setup which is the right use case for this change.
Moreover the L3 cache on CPU is what makes significant difference, IMO.
If that is true, not sure how much improvement consumer-grade desktop will see, given that most consumer-grade CPU will not have that much L3 cache on chip.
AMD has been putting a lot of L3 cache on their consumer CPUs. The 5800X3D has 96mb of L3 cache.
Yes, that’s true. Only if Intel follows the same in future.
On a separate note, 5800X3D seems to be most efficient (throughput/watt) consumer grade CPU out there right now.

Pretty sure the 7800x3D surpasses it and the 7950x3D is no slouch either.
Their top-of-the-range Epyc 9684X has 1152MB :)
That’s definitely a CPU for server (unless you are a general consumer with lots of $ 🙂 ).
There definitely are vendors ignoring common sense and putting socket SP5 on desktop boards.
No argument about the price, I think list on these is something like $13k USD.
Man looking at my old 5960x with it’s 20mb of cache from 2014, and Intel’s current top consumer chip with 36mb.
Crazy to think Intel were ‘ahead of the curve’ so long ago, those x99 chips are still relevant compared to some AM4 chips.
This proves once and for all that Linux is the superior platform!
when was the last time you heard any such news for PC or MAC?
when was the last time you heard any such news for PC
A few seconds ago, when I read that the new Linux kernel contains TCP related performance improvements!
This has to be some sort of Dunning-Kruger effect right here…
Dunning-Kruger
This is more a case of tongue-in-cheek
