MTU and Gaming

[masterfalcon3000]

so i recently found that when i change my mtu it does affect my packet loss and ping on online games so i want to know the right way that nobody answered in google .. is the following steps right ?


1- set mtu for both ipv4+ipv6 to 1500 in cmd for my windows
2- test the mtu until i get the 0% packet loss and no fragment so mine was (1464)
3- add 28+1464=1492 and put the 1492 into the router settings


The question is :

1- Should i change the mtu for both ipv4+ipv6 to 1464 ?
2- Should i change the mtu of the router by adding 28 to 1464 = 1492 so the 1492 into my router mtu settings ?
3- should drop the mtu lower than that to get better ?


Thanks in advance

Just leave it at default imo., some games will actually prevent you from using frames larger than 1.5k

You should not have to mess with the MTU. A well written application can detect the MTU and just send less data if it has some issue. This used to be much more a issue because wrong MTU causes packet fragmentation which caused more cpu overhead but processors are so fast that it seldom is even detectable.

The MTU can actually be different for different servers so you can't really manually set it in any effective way so you are better off just leaving it alone and let the software do its job. Besides you can only set it on one end anyway the server will do what it wants.

Unless you need IPv6 for some reason best to just disable it. Even when it works there is massive overhead because of the header lengths compared to ipv4. Many times IPv6 has poorer routing because it is still not fully supported by all ISP....even though they have been saying for the past 20yrs it is the future of the internet.

1. If you have real ipv6 (not some tunneling protocol) then the ipv6 mtu should be 1500. ipv4 should 1492.
2.
3. Go lower if it lowers your packet loss. If going lower makes a real difference in ping, then sure ... if your talking 2 ms, don't worry about.
