Extreme LAG on Minecraft multiplayer

[Sandrituky]

Hello! 

 

My boyfriend and I have set up a forge server with around 50 mods. The forge version is 1.12.2-forge1.12.2-14.23.3.2674. He's hosting it and he's allocating 5GB RAM for the server and another 5GB for his client. He got a bit delay but... I can't even play. 

I have two computers, one desktop and one laptop, I set up the forge server yesterday with mods on my desktop PC and I could run the server and the client with no problems and I sent the files to my boyfriend because he has 8GB more on his PC. He only changed the forge version to the mentioned one (I set up the server with an older one). 

 

This weekend (and every) I'm on his home and I use my laptop. My laptop specs: https://pastebin.com/L71rMiGY

 I installed the forge client from zero and copied-pasted mods. I have 100-150 FPS on singleplayer mode, but I have around 0,1 FPS on the server (with no shaders!!). I have allocated 8GB on Minecraft launcher... I noticed that Minecraft was using integrated graphics but I changed that with Nvidia Control Panel, so now it's using the Nvidia GeForce 1050 Ti Graphics. 

 

I'm next to him, so we are playing on local, he has 300MB speed on upload/download (symetric). We've set up more forge servers years before with a similar numbr of mods to play beetwen us and some friends, and I could play well from my desktop PC. 

 

What is happening with my laptop or with this server? I know I should test his server from my desktop PC and I may do it in a few minutes via remote. We have no crashes but I will paste the lastest log from my client and his server.

 

My client: https://gist.github.com/Sandrituky/bf364b9828000a9f3ddb137c4322d512

The server: https://gist.github.com/Sandrituky/f40fdc066da51ce682c062f0a19eb271

 

PD: I have a program called Killer Control Center that increase networks performance and these things, and I have Minecraft with priority = 1. Could that program be causing issues? 

 

 

Thank you all for reading me! Happy gaming!

Hi,

 

Personally, I would start with some basic debugging steps

• Yes the program could possibly be causing issues I would try disabling it 
• If at all possible try connecting the two computers via ethernet either via crossover cable or a router
• Make sure you are using the local IP not your public IP to connect to the server usually are 10.0.0.0 or 172.16.0.0 or 192.168.0.0
• Try using the forge version you used when you set up the server
• You could try removing Roguelike Dungeons which seems to be generating a lot of structures

If these don't work could you upload your server start file and a list of mods?

 

Hope this helped.

Hi, thanks for the reply!

 The first thing I've tried is to run the server I had created at beginning on my desktop PC (via remote connection). I logged in from my laptop and it's unplayable. My boyfriend logged in too, and he could play perfectly. In conclusion, my laptop seems to be the problem, it must be something about connection. There must be a way to solve it... it has enough power...Hi, thanks for the reply. The first thing I've tried is to run the server I had created at beginning on my desktop PC (via remote connection).

In conclusion, my laptop seems to be the problem, it must be something about connection. There must be a way to solve it... it has enough power...

 

I've disabled the program from services, I've disabled its start too and restarted the laptop and... nothing changed.

I was using the local IP the whole time. 

We haven't a crossover cable here, so that's the only thing I can try right now.

I tried the another forge version (the first thing I tried and I wrote) from my desktop PC. 

My boyfriend removed Roguelike Dungeons and nothing changed for me... 

 

The only diference is that he's using Ethernet connection and I'm using wifi (5G, and I receive almost 300MB on upload/download... the next thing I'm going to try will be to take his Ethernet cable on my laptop, I will report what happens, I don't think that's the problem but I must try everything on my hand). 

 

Update: I tried to connect my laptop with his Ethernet cable and... nothing changed. It's unplayable, I don't know what to do! 

 

(Noone of us are using hamachi, we both opened Minecraft ports in our desktop computers and I got disabled Firewall on my laptop/desktop PC). 

 

List of mods: https://pastebin.com/NeuYFsb1

His server start file: https://pastebin.com/PRbm9mFB

My server start file: https://pastebin.com/dWHiRNZG

 

He had almost the same start as me before, but he removed arguments looking for a solution. We don't know what some arguments means and neither which could be the perfect start file for us. 

 

Thank you again!

@ECHO OFF
java -Xms1G -Xmx4G -jar forge-1.12.2-14.23.3.2655-universal.jar nogui
pause

 

I would use this for your start file

@ECHO OFF - suppresses some stuff I don't know exactly what it does but windows want it

Java - tells it its a java program

-Xms*G - starting gigabytes of ram

-Xmx*G - max ram

-jar ***.jar - name of the jar

nogui - tells it to run in command prompt 

pause - another windows thing

 

I noticed in both scripts the memory flags were used incorrectly they were either the values or misspelled try using the script I provided

None of the mods look like they would cause conflicts off the top of my head

If this doesn't solve the issue could you please post your (while the server is not hosted on your computer) ping to the server and your FPS in game

you can find your ping in the server menu by moving your mouse over the bars next to the server.

Hope this helps

This stops cmd from parroting commands back to you before they run

Hey, thanks again for your reply!

We changed the run script and my boyfriend is experiencing less lag (when he hit a mob, there was a delay, that's seems fixed). But I... I logged in and the first 2 seconds there was around 60 FPS, but suddenly it went to 0 FPS. 

Ping is 4ms. 

I post here these screenshots about ping and FPS. When I'm ingame and I press ESC, the menu lasts around 5-10s to open... 

 

 

I can't really understand this 

 

[MDW01]

So it is definitely not your connection to the server. The Issue seems to be something else. Your hardware should be more than capable of running this but even the best hardware is vulnerable to software bugs. I don't know what to tell you other than removing all the mods from your client and the server and connect to the server with only forge installed. Then if your issue goes away add the mods back one by one until you experience the issues again and that mod will be causing the issue. This can be an annoying process but it is a last resort.

 

Hope I helped

Those two lines are the only ones reported in the server log after you're detected connecting to it. That is a pretty big tick delay, and Thaumcraft also appears to be the only one in your list with "BETA" in its filename. In any case, beta versions can be unstable (that's why they're beta). I would start by attempting to remove this mod from your installation (and any dependents) and if that doesn't help try other mods one by one until you can find the problem.

What about them?

Sorry, I apparently hit Control-Enter which in my browser posted my message prematurely.

Also, JourneyMap can implicate extreme lag spikes:

 

Especially if your server is fresh, and even moreso if being hosted from an underpowered desktop PC (relatively speaking by server hardware standards). So, another few steps you could try would be Crowfooted's and InThayne's commented suggestions in that above Reddit thread, regarding checking with Shift+F3 to see if anything's chewing CPU on your client side, and regarding the JRE garbage collection parameter (try that one on both your client and server startup commands).

SOLVED!! 

 

It's solved, but I want to die. You won't believe which mod was causing the trouble. It was a client-side mod I had installed!! It's called Better Animals Models. 

I never thought that a client-side mod could cause this lag, the most funny is that it only happens on multiplayer. On singleplayer mode everything works perfectly! 

The another must funny thing is that my boyfriend requested me to search the link for him, and I downloaded it for giving it a try, but he didn't download it because he forgot about it. I want to cry very hard  

But I'm happy because we will be able to play finally together and with friends!

 

Thank for all the replies @MDW01 and you too @kevinmd88  

 

 

Now 80-90 FPS with Shaders !

Glad I was able to help.
