Hey so I’ve finally found something measurable that makes a difference in my input lag and network desync issues.

Network issues are along the lines of desync (people move way faster than you, you dodge something but it hits you) and hit reg.

Waveforms bufferbloat test always scores terrible, but I got a new router that scores an A right out of the box. No SQM or weird thing I have to enable.

That fixed my hitreg.

As far as input lag id describe it as your pc not feeling responsive. Since I fixed my hitreg first, the input lag was still there so my shots were hitting but my controls of my character were not responsive. Mouse movements, WASD, etc.

What fixed my input lag was getting my AIDA64 memory latency to an acceptable range. I had this fancy g skill Royal Elite ddr4 which I put back into my PC, at 3600 mhz 14-14-14-34.

That changed my ram latency from 70ns to 64ns. That fixed my input lag.

Are you sure it's not a temporary effect?

This is a temporary effect

Want to try an experiment? If you have 4 RAM modules, remove 2 of them and leave them sitting around for a week. Once the week is up and you reinsert the RAM module that was previously in use, you’ll experience a temporary improvement lasting anywhere from an hour to a day—unfortunately, the duration varies from person to person. This also works with all peripheral devices. I personally experienced a temporary improvement that lasted two days. Before New Year’s, everyone decorates their homes with string lights—I hung them over two windows and plugged in extension cords, and I also connected the Christmas tree to the extension cord near the PC because it was simply closer. So who knows what the problem is and why the peripherals give a brief boost… Check this out—it’s way better and safer than heating up the RAM with a hair dryer, like trying to “train” it, ha ha.

You will find thousands of posts with people having perfect bufferbloat but having desync constantly.

I still think the majority of the reason is down to internet routing

Absolutely, you are right : Internet routing is more important and impactful than bufferbloat, which happens only at full throttle anyways.

I have two fiber connections at the moment from two different providers.

-one XGS-PON 2.5Gb/s Up and Down with perfect bufferbloat at full speed (A+ score with +0ms down and +1ms up)

-and a second GPON 1 Gb/s Up and Down with C score bufferbloat at full speed ( C score with +5 ms down and +65ms up)

The second one with worse bufferbloat is way better during gaming, mainly due to better peering and a stronger BGP than the first ISP.
I recommend looking for a tool called "Looking Glass" from your ISP where you can see how routes are interconnected and handled by your ISP; like which route is the main one used, which gets prioritazed, which is a "fall back" route, which is going through an IXP or a transit IP, etc.

If your ISP is serious this tool should be available publicly but most ISP refuse to share it.

Iperf3 UDP test gives a better understanding than bufferbloat IMO. Waveform Bufferbloat website is really nice, i talked to the people working at Waveform in the past but it's a TCP protocol test hosted by a CloudFlare CDN.

Online Games most of the times use UDP packets hence why i recommend doing an Iperf3 UDP test. You wanna mainly look at the jitter value.

this is how to do it :

1) download iperf3 for windows : https://github.com/ar51an/iperf3-win-builds

2) unzip it, open the folder and type "cmd" in address bar (the bar where you can see folder path)

3) when command opens type : iperf3 -c <SERVER IP> -u -i 1 -t 10 -b 10M
(chose IP server from this list :https://github.com/R0GGER/public-iperf3-servers)

4) wait for result and check jitter, post your result here if you wish. to change the bandwith amount change the number after the -b. in this case i chose 10mb because most online games uses lower values but you are free to choose the value you want.

By the way, you can have TCP bufferbloat without really impacting UDP, as much as you can have perfect TCP bufferbloat score and a jittery or bursty UDP. It all depends how your ISP infrastructure is made and how it handles those protocols.

I tried iperf3 and here are my results, they look ok but the desync issue is killing me (behind server feeling)

Do you experience UDP jitter with perfect waveform bufferbloat scores?

If thats measurable than sure I have no issues acknowledging it can cause issues.

But not everything is network related, you just need to fix your network so you can fix what else is messing with your system.

Fixing my network first was a funny experience because I got to feel my system's lag without my network lag, and although it's impossible to figure out which ones which when both are happening simultaneously, when one is isolated it does show different behavior.

It was like having training weights on every since one of my movements. But the hitreg was still okay.

But anyways im curious as to how you are having network issues with your fibre connection with a perfect bufferbloat. Are they putting you on CGNAT?

Also do you have SQM enabled on your 2.5g router? SQM can get your buffer bloat scores to an A but I’ve heard it can also cause issues. It’s like a bandaid that works but can cause side effects.

When I got a new wired router it doesn’t have SQM, and out the box it gives me an A on waveforms test. I’m assuming that it just has proper provisioning of bandwidth
