No FPS gaming possible

[LaggyTyp]

I think the reg options DefaultSendWindow and DefaultReceiveWindow can have an impact on packet bursts.

My observation:

Windows 11 ("Stock"): The game displays a download bandwidth of approximately 350-500 kbps.

DefaultSendWindow + DefaultReceiveWindow = 131072 (decimal): The bandwidth is very often below 200 kbps (because packets are bundled).

I'm trying to understand the connections and find a solution for myself.

There is a solution, but I'm not satisfied with it.

If I increase my outbound ping by 50 ms, for example, the game runs better, but I still crash very often.

It's also possible that my ISP is bundling the packages. Then I'd be completely powerless.

I wish there was a setting in Windows 11 that would fix my problems, but no matter what I change, it doesn't work.

It's so frustrating.

Location: Germany (large city)
Game: e.g., BF2042
Game Server: Frankfurt
Latency: 12-15ms (usually 14ms)
Internet: 1000/50 DOCSIS (cable internet)

- I need so many shots to take someone down that all the enemies in the area become aware of me (often the entire magazine)
- No surprise attacks possible
- Every player on the server, from novices to pros, can anticipate my moves
- Sometimes it's so bad that I'm already being shot at before I even look around the corner (when I watch streamers, I see them running around the corner and calmly taking out several enemies)
- I'm more of an aggressive player. But currently, I can only play very cautiously.
- Everyone has a peekers advantage on me.
- Game runs completely smoothly
- No error messages like packet loss or similar

The game sends approximately 51 packets (in and out) per second. The bandwidth is extremely low.

I die in 5-10 ticks (45Hz tick rate).

Time for 7 ticks = 7 × 0.0222 seconds ≈ 0.1556 seconds (or 155,6 ms)

This can't be true!?

EDIT:

By the way, at the beginning of a round, I don't hit anyone, and if I do, it doesn't cause any damage. It only gets better after a few minutes.

ask ur isp to provide u better peering to the servers usually they ask this if u buy bussines package(every isp is different not all the time) u can get it on normal plans aswell but it will take some days of phone calls

That's absolutely possible. The fastest TTK in BF2042 is the PBX-45 with Close Combat ammo and either the 6KU or Wrapped suppressor. It has 28 base damage with 900 rounds per minute of fire rate, which means it takes 4 bullets to kill with bodyshots only, up to a distance of 9 meters. This means the TTK of the PBX45 in full-auto without headshots at up to 9 meters is 60/900*(4-1)*1000, or exactly 200 ms. The headshot multiplier for SMGs is 1.55x. If someone exclusively shoots you in the face at a distance of up to 9 meters, the BTK goes down to 3 while dealing a damage of 43,4 per shot. This makes the TTK 60/900*(3-1)*1000, or 133,3 ms.

So yes, a TTK of 155,6 ms is absolutely possible and you can actually die even faster than that.

It's also possible that my ISP is bundling the packages.

A friend of mine lives in a medium-sized City (around 80k) also gets her internet from Vodafone. It's also DOCSIS and it's 1 GBit/s as well. No signs of problems for her, she plays any game just fine without noticing anything wrong whatsoever. Watching her play games like Valorant or CS shows no anomalies and the games work as you'd expect. Another friend is also a Vodafone customer, in a decently large city (about 300K), but he's on VDSL, and he doesn't experience anything like this either. Watching him play also looks totally normal. I don't think Vodafone does this.

The game sends approximately 51 packets (in and out) per second.

Doesn't seem right. You're supposed to receive 45 packets per second, as that's the game's tickrate. It should look like this:

I don't really know what this would hint at, other than the server being borked in some way, or it's a measurement error of some sort, but if what the measurements tell you is actually true, it can't hurt receiving more than the actual tickrate as you're getting more information than usual. It could hint at something, but unless your graph looks like a seesaw it should be fine.

Small bandwidth is normal. Here's mine:

As you can see, the packet size hovers just about the 200 kbit/s mark. This was on a nearly full server of 64-player Conquest on the map "Redacted", as you can see from the time scale it wasn't too long of a sample but I've gotten about 20 kills here. The run-up at the start was me loading into the round, the spike in packet size just after the 25 second mark is me spawning into the game and the sharp drop-off at the end is me ALT+F4'ing out of that POS game as soon as I got killed and the killcam was over.

Is Wireshark running on a different system? When I start Wireshark, BF2042 is blocked. I can't run them together.

I've been playing BF2042 since release. It's never been like this. People can kill me in seven ticks from the other end of the map. I'm literally being destroyed by everything and everyone.

Back then, I was getting 60-100 kills per round. Easy. Now, maybe 20 kills are possible.

Yesn't. The packet capture was done by the router itself (a Fritzbox 7590), and the file it produced I just opened with wireshark on my PC after the fact.

I've been playing BF2042 since release. It's never been like this.

I know what you mean, I was just pointing out that being killed within the time frame of 155ms isn't inherently impossible and it can indeed happen. I'm not doubting that the game is wrong for you, I've seen it myself and I know exactly what you're seeing.

Back then, I was getting 60-100 kills per round. Easy. Now, maybe 20 kills are possible.

Again, I know exactly what you're experiencing as I've seen the exact same thing before. When I change up my system in a specific way, I can make the problems come right back, and it's literally impossible to kill anyone who's looking at you. The terrible netcode seems to amplify the problems compared to games with decent tickrates like CS. Funnily enough, the game I just played to capture the sample I was immediately called an aimbot cheater by someone in the enemy team. And yes, while that's not rare and people are indeed "mad cuz bad", when the problems are present, I'm never getting called a cheater ever, even if I hit some nasty shots.

Can you explain to me how you collect the data with the Fritzbox and then view it with Wireshark? Instructions?

[ChristophSmaul1337]

Yeah sure, no problem.

I'm assuming you're on a relatively modern FritzOS, like anything 7.xx+.

1. Open the FritzBox web interface and log in with your password
2. On the left, click on "Hilfe und Info"
3. Scroll all the way down and find "FRITZ!Box Support". Click on it
4. You should see a new page open up. There should be a section called "Paketmitschnitt", and there should be a clickable link named "Paketmitschnitte". Click on that link
5. A new page should open and you should be able to start the capture on any inferface you want. I used "1. Internetverbindung" but you should be able to use "eth0" or "wan" as well
6. In my case, it downloaded a .eth file. You can run Wireshark after you're done playing and open the file with it.

I assume you're familiar with Wireshark and know how to get the I/O graphs and know the filter options.

[LaggyTyp]

Unfortunately, I don't know anything about Wireshark.
