300-400 ms of latency isn't actually that insane, nor should it be causing disconnections. That's what usually happens at 2-3 seconds (2000 - 3000 ms) of latency lag. How do you know its the latency? What server are you trying to connect to?

The idea of tracert is checking what the route is between you and the server you are trying to connect to. This might give you an idea at what point the connection starts having issues.

Add this mod to your modpack: https://www.curseforge.com/minecraft/mc-mods/notenoughids/files

Are you absolutely sure you downloaded the right Forge? The forge you included is this one: "forge-1.12-14.21.1.2443". Like, that's not even the right version for the version of optifine you included (and I should add, I have no fking clue where you got that particular one. Certainly wasn't from the optifine site).

Yes, that's a nice amount of words. Could you also include stuff like the modpack name and your save file?

Have you done a tracert (cmd.exe -> tracert IP) to check where the higher latency comes from?

You did not. The forge included is for 1.7.10.

What's the full name of the forge file you are using (before you renamed it to modpack.jar)?

Which forge did you add to your 1.12.2 modpack? Checking the jar will give you the answer.

So yeah, downgrade your java to 8u51.

You'll have to try and update your intel graphics drivers. Use this intel program: https://www.intel.com/content/www/us/en/support/detect.html

Like, the F8 "Cinematic mode" key?

Looks like a Forge library wasn't downloaded properly during the modpack download/installation.

http://launcher.technicpack.net/resources/OpenSans+Cyberbit.ttf Open that, what happens?

It's an issue between Windows 10 and the intel HD graphics drivers. Let's just put it like this, some older Intel chipsets shouldn't have had the upgrade to Windows 10, as they aren't fully supported by Win10, and when it happens, you get this. Its some weird incompatibility between Java 8u60+, Win10 and certain Intel HD drivers.

This tends to fix itself after about 2 hours. Don't search too much with the launcher, use the technicpack site here instead.

Downgrade your java to 8u51.

Direct Copy/Paste from the discord bot: Forge, Technic Launcher, and Minecraft do not support Java 9+. Follow either the manual or script instructions to remove it and replace with Java 8: Script 1. Close the Technic Launcher. It cannot be running! 2. Download this file: https://download.uskarian.net/scripts/mac-delete-java9.command 3. Open terminal 4. Copy and paste: chmod +x ~/Downloads/mac-delete-java9.command 5. Copy and paste: sudo ~/Downloads/mac-delete-java9.command If it asks you for your password then type in your password. You will not see text being entered as your type, but it is being entered! Once you've typed your password hit enter on your keyboard. 6. Download Java SE Development Kit 8u191 from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 7. Install the jdk-8u191-macosx-x64.dmg you just downloaded. OR Manual 1. Close the Technic Launcher. It cannot be running! 2. Open terminal 3. Copy and paste: sudo rm -rf /Library/Java/JavaVirtualMachines/jdk-{9,10,11,12,13}*.jdk/ If it asks you for your password then type in your password. You will not see your password being entered as your type, but it is being entered! Once you've finished typing your password hit enter on your keyboard. 4. Copy and paste: sudo rm -rf Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin 5. Copy and paste: sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane

3.5 GB RAM is not enough to play modded 1.12.2 with a texturepack.

Yeah, you need to use Java 8. You are probably using Java 13.

It's the same file you used to install the launcher. You do need to save it somewhere. If you run it after download, it goes to ~temp, aka, removed after use.

Download 64bits java. Download the OFFLINE installer from java.com for that. Allocate 2-3 GB in the launcher options menu after installing java 64bits (and restarting the launcher).

So uh. I downloaded the same modpack you were using. I removed the older forge, and added the same forge you are using. Got it started for a bit before the older Optifine version broke it. Quite unsure what you did so it doesn't work. The error in your log usually means wrong Forge/Minecraft version.

Go to the .technic folder -> modpacks folder -> the modpack you are playing -> follow this path /saves/mapwriter_mp_worlds/meincraft_apexmc_co__25590 And delete the mapwriter.cfg:1 file, as it is corrupted. This will let you join again.

What version of Forge are you trying to add?
