hello,
i want to setup openwrt specifcly for gaming (fps) my ping is 100ms
is there a good qos (not sqm) made specifcly for gaming
You can just search for Call of Duty in this forum to see other options. However, what you want is to reduce latency. Depending on your hardware, one option could be better than another, so read here and there to find the best configuration for your rig.
In my case, with a Linksys E8450 —an AX3200 wifi 6 router— I was able to reduce latency from 105-110 ms to about 20-25 ms under load by installing the luci-app-sqm package and using this /etc/config/sqm config file:
config queue 'eth1'
option interface 'wan'
option debug_logging '0'
option verbosity '5'
option qdisc_advanced '1'
option squash_dscp '1'
option squash_ingress '1'
option ingress_ecn 'ECN'
option egress_ecn 'NOECN'
option enabled '1'
option download '900000'
option upload '45000'
option qdisc 'fq_codel'
option script 'simple.qos'
option linklayer 'ethernet'
option overhead '18'
option linklayer_advanced '1'
option tcMTU '2047'
option tcTSIZE '128'
option tcMPU '0'
option linklayer_adaptation_mechanism 'default
You just need to adapt the interface name and modify the option download and option upload values. Those numbers are the bandwidth in kbps. Start using 10% below your max bandwidth and increase them until your latency starts rising beyond your desired threshold. You can use several tools for testing it such as fast.com (using the extended info) or the excellent https://www.waveform.com/tools/bufferbloat that can give you independent values for upload and download. However, since you already have ways to measure the ping inside Call of Duty, then just use it for testing the best number for you.
You can also use qosify for the same thing.
