I want to try netem for a while and I read on another forum that it is better to apply it to the output, I notice that when I play on European servers with low ping the game feeling is heavier than when I play with server above 100 ping, so the idea of increasing the ping on nearby servers. And yes, my connection is 1gb. I am currently using proxmox and a virtual machine for openwrt and so far it works pretty good in general. Still I feel that the gaming feel can be improved even more.
You can try whatever you want, but Netem wonât improve your gaming experience... it will likely make things worse. Feel free to test it, though... Iâve done multiple tests with it, and Iâve yet to find a situation where it had any positive effect.
I will try it during the day. As far as I can see for you the best option is to use the qdisc Red?
Exactly, but it shouldnât make a huge difference
So adding delay is an attempt to "game" a game's lag compensation... and the hope is that the disadvantage of adding really delay is less than the advantage of getting treated better by the lag compensation system. Without any decent theory how the lag compensation actually works and which thresholds or mapping functions it uses, this is an exercise in trial and error against essentially a black box....
Getting robust and reliable data on whether (or how much) delay helps is looking like a long and arduous slog...

It is not about reverse rules, port that matter for CoD is assumed to be on game console not on the server, so of all rules none matches the game traffic.
While each game may implement lag compensation or server rewind differently the fundamental techniques and underlying logic are publicly accessible.
Above is a good explanation.
Below is a nice represenation
These systems generally store historical player states (positions, rotations, hitbox data) in buffers and then ârewindâ the game state using factors such as network latency, client-side interpolation etc...
Attempting to add artificial delay in hopes of gaining an advantage is a risky gamble which can easily backfire and put you at a disadvantage. In short, without a deep understanding of the gameâs specific thresholds and processing logic, trying to manipulate the lag compensation system becomes a trial-and-error battle against a black box, just as you correctly pointed out.
Also, if the game transmits game state and clock information within the network packets, then artificially adding latency wouldnât probably directly influence the serverâs decisions. The server evaluates actions based on the actual timestamps in the received packets rather than just their arrival time. As a result, intentionally increasing latency could simply cause your packets to arrive too late, likely creating more problems rather than providing any advantage.
I was downloading a game yesterday and there were a lot of tcp dup ack and retransmissions, is it normal? 50% packets
I used this guide to set up my CAKE and now I can set the download speed to 45 Mbps, which is close to my actual package speed, and the results are fine for bufferbloat.

```Platform console XboxFix your ruleset, it needs dst port 3074 and maybe src port xxxx wiithout any IP selected
Clear these two and change protocol to tcp+udp.
Exactly in opposide order - first apply the settings then check the network communication.
I applied the settings and rebooted the router and still not work
@brada4, let's not confuse @raynelv any further.
I believe that his underlying issue is likely not related to the rules he's using. The sample rules provided in the README work for everyone else, so thereâs no reason they shouldnât work correctly here. Even if he initially set up redundant and far too many rules, DSCP should still appear somewhere in the connections tab since TCP_UPGRADE_ENABLED is set to '1'. However, if you review his previous screenshots, his connections tab shows DSCP as CS0 for every connection.
Also if you look at his previous posts you can clearly so traffic is hitting his cod rules:
Here are some potential issues - @raynelv Please read carefully and provide answers to the questions. :
- Do you have offloading enabled â please show us the output of
cat /etc/config/firewall? - I'm not sure whether his device (EdgeRouter 4) is using lan0 as the WAN port in the default configuration... have you made any changes that deviate from the default configuration? Perhaps lan0 isnât routed through the CPU. If you're not using the default config, you might try performing a factory reset and starting over with the default configuration to test qosmate.
- Perhaps he is also affected by the bug that @Ridz encountered (and also @Knomax) â see QOSMate / Cake w/ DSCPs. In that case, could you provide the output of:
nft -c -d netlink add rule inet dscptag dscptag ct mark set ip dscp or 128 counter
nft -c -d netlink add rule inet dscptag dscptag ct mark set ip6 dscp or 128 counter

A useful debugging tool may be to add a trace flag to a rule definition so you insert a rule that enables meta nftrace set 1 for the same criteria. Horrible sentence structure, I know. Example:
# debug rule:
ip saddr 192.168.10.2 udp sport 3074 udp dport 30000-65535 meta nftrace set 1 comment "debug: cod1"
# userâs rule:
ip saddr 192.168.10.2 udp sport 3074 udp dport 30000-65535 ip dscp set cs5 counter comment "cod1"
Then have the user run nft monitor trace while testing the rule. Youâll see what happens to the packet after the rule is encountered.
Rule kind of works (counter) but the connection (conntrack mark) is not tagged.

Issue Description
Ping spikes in Counter Strike 2 while TV is streaming
When did it start? (After an update, configuration change, etc.)
Since we got a new TV that supports 4K 
Can you reliably reproduce the issue?
Yes
What have you tried to resolve it?
Many SQM solutions
Steps to Reproduce
Start streaming on TV
Expected Behavior
No ping spikes in Counter Strike while streaming is not affected negatively
Actual Behavior
Ping spikes any few seconds in Counter Strike 2 or with ping command
Have you reviewed the QoSmate documentation?
Yes
Have you checked the OpenWrt forum thread for similar issues?
Yes
Are there any relevant log messages? (Check with logread | grep qosmate)
No
If gaming-related, what game/platform are you using?
PC, Counter Strike 2

Thatâs why Iâd be interested in the nft trace output, to see when the packet traverses the ct mark rule and what else might come after it (e.g. another chain from a different script).
