Blur Busters Forums

Bufferbloat is existing only when link is full. When you playing and nobody downloading torrents at full speed - you will never see bufferbloat. Bufferbloat on ISP router is of out your control, so internet gaming is RIP. Thanks to youtube/netflix/instagram reels and other shit.

I offered a bribe to an employee. The official contract for the provision of services has not changed. Authorization and routing have changed, all traffic is processed as traffic for a commercial organization, and not as for an individual.

And what this trick changed in gaming?

Today only short answers. Later I will try to provide more information.

Would a router with SQM be a solution for bufferbloat?

No, for most gaming scenarios, they utilize like less than 1% of theoretical bandwidth.
They maybe make sense when you have 5000kbit speed and your roommates watching ponhub.

It's similar to my connection (Vodafone 1Gb) receiving A or B.
I had a second router, Ac68u, that runs the custom firmware (Merlin) that supports fq_codel.

I noticed that for 1Gb, the router could not sustain the QoS and the CPU reached 100%. I had to reduce the bandwidth to 25Mb, and now I can have A+ with 0ms.

On 1gbit/s speeds you dont need QoS at all.
And any consumer router cant do this at 2022, even 4-8 core ~2ghz dont enough for that packet rate. You can QoS about 250-300 mbit if your router can process packets in multicore.

Depends on what others do. If the others do lots of downloads, then yes, even 1 gbit/sec still needs a bit of QoS.

You can do efficient gigabit QoS by using two separate routers.

One WiFi-disabled high performance router just for gaming, with only two devices connected to separate Ethernet ports.
- The gaming PC, directly by Ethernet, given highest priority
- The everything-else router (WiFi-enabled) to another port, given lowest guest-network-league throttled priority.

That way, router workload is kept very low for the gaming PC, and keeps the gaming router CPU lightly loaded with minimum local-side bufferbloat / minimum jitter.

Then you only need Ethernet-port-level QoS, which is extremely lightweight and low CPU overhead. This avoids CPU-hogging packet-level QoS, which is the problem you refer to.

Yes, cap your everything-else router to up to 20%-30% of your bandwidth during your critical games, then uncap to 80%-90% rest of the time. Downloading Steam games at 200-300 Mbps (20-30 MBytes/sec) is still First World Problems. Or even go further, cap to 10%.

You still have ISP bufferbloat to deal with, but then you don't have to worry about CPU overload on your gaming router!

That way, your roommate's 100 megabytes/sec sudden Steam download won't suddenly interfere with your game, downloading Cyberpunk 2077 in less than 15 minutes but wreaking havoc with your CS:GO game. Your roomies or family may still need to take longer to download stuff, but then your competitive games merrily play almost as if nobody else is online.

Almost all who started suffering from any kind of desync or "input lag" starting from turning off all clients from router or using direct connection to bypass router, and that doesnt help in like 99% of cases, so bufferbloat if you have 1gbit symmetrical connection is the almost last thing to worry about, and you can clearly see corellation between your homie downloading torrents and your lags.
