MTU size - packet summarization possible?

Question

Computer networks

I noticed that with a different MTU size, when playing an online game (overwatch), the responsiveness of the game is different.
The computer (intel network card) is connected directly to the provider's equipment i.e. there is no router.
There was a 100Mb tariff, now the 300Mb tariff depends on MTU has not changed.
With a "standard" MTU of 1500, responsiveness in the game changes, usually depending on the time of day. I tried to put a different package MTU. When changing from 800 to 1500 in increments of 100, the difference is not noticeable. From 1400 to 1500 I changed in increments of 10 - there is no difference either.
But when setting a large MTU, there is a noticeable improvement in responsiveness.
I checked it repeatedly, it costs, say, 1500 and in the game there is some kind of wadded responsiveness, I put MTU 4000 and the responsiveness gets better. I also set 8000 and it was also better.
But if you set 3000, then noticeable friezes begin in the game, characters sometimes start to move in jerks, the same thing with MTU = 6000. The

question is - if the MTU is large, then small UDP packets can be combined into one?

The meaning is this - with a small MTU size, the game sends a UDP packet of a "standard" length, some of them may be lost or buffered. And if the MTU size is large, then the game in one large packet pops several small packets at once, as a result they arrive at the same time, and not with delays due to losses or buffering.

Answer 1

There, on the contrary - the toy sends large packets, and the routers cut them into small ones, if one part of the small one does not reach - bam, the entire packet is lost.

Answer 2

I checked it repeatedly, it costs, say, 1500 and in the game there is some kind of wadded responsiveness, I put MTU 4000 and the responsiveness gets better. I also set 8000 and it was also better.
But if you set 3000, then noticeable friezes begin in the game, characters sometimes start to move in jerks, the same thing with MTU = 6000.

And on the router, too, is the MTU raised? Did you also raise the game on the server?
I haven't read such game for a long time, write more

Learn mat. part citizen.
At least read this article - https://help.keenetic.com/hc/ru/articles/214470885... . And then ping with the packet size that you set to the game server. it's all there and you can see it. From mat. parts - then if the server does not give by itself such a block of data with the required volume, then it is filled with not useful information so that the size is suitable, that is, in fact, in a second of time with a smaller MTU, we can have 1.5 times more in a second useful data than with large. Read an old book - computer networks, upgrades and troubleshooting from bhv.

Answer 4

for an online game, I advise you to put mtu less, firstly get rid of fragmentation, secondly there is less chance that the bag will not reach
