BattleTech Visual Distortion Field Calibration
Experiencing graphical glitches or distortions in the heat of your Mech battles? Your MechTech team has some tweaks to realign your HUD:

:hammer_and_wrench: Adjust Your System's Visual Settings:

First Step: Ensure you're using a quality text editor like Notepad++ to make these adjustments. This will help avoid formatting issues that can occur with more basic editors.

Edit the Megamek.l4j.ini and Mekhq.l4j.ini files in your game directory with the following flags, tailored to your system's memory:

For Standard Systems (8-16 Gig):

-Xmx2048m -Dsun.java2d.d3d=false
Or, use -Xmx2048m -Dsun.java2d.opengl=true for OpenGL support.

For Advanced Systems (16 Gig):

-Xmx4096m -Dsun.java2d.d3d=false
Or, -Xmx4096m -Dsun.java2d.opengl=true

For High-End Systems (32 Gig):

-Xmx8192m -Dsun.java2d.d3d=false
Or, -Xmx8192m -Dsun.java2d.opengl=true

UI Scaling Issues?
Some MechWarriors have achieved clarity with -Dsun.java2d.uiScale=1.

:notebook_with_decorative_cover: Instructions:

Locate the .l4j.ini file for MegaMek or MekHQ in your installation folder.
Open it with Notepad++ or another quality text editor.
Add the appropriate flag(s) based on your system's memory.
Save the changes and restart the game.

If distortions persist in your Mech's cockpit, report to your nearest MechTech for further diagnostics. Your contributions help keep the Inner Sphere's technology at the cutting edge!

Is Notepad ok or do i need notepad++ or a code editor like VS code ?

sly grotto Dec 14, 2024, 5:47 PM

#

notepad is fine

polar scaffold Dec 14, 2024, 5:47 PM

#

Ok ty

#

Still having it, are the flags correctly written ? I have 32Gb Ram

sly grotto Dec 14, 2024, 6:00 PM

#

are you starting megamek from mekhq? if so need to update the mekhq ini also

polar scaffold Dec 14, 2024, 6:01 PM

#

Mekhq has stricly the same parameters

sly grotto Dec 14, 2024, 6:01 PM

#

also need to restart completely

polar scaffold Dec 14, 2024, 6:01 PM

#

I edited them

#

Also done

sly grotto Dec 14, 2024, 6:02 PM

#

i usually put this on a new line -Dsun.java2d.d3d=false instead of after the other part

polar scaffold Dec 14, 2024, 6:03 PM

#

Ok I will try

#

By the way 8192 is only tied to RAM or do I need to also take into account CPU and GPU power ?

sly grotto Dec 14, 2024, 6:04 PM

#

just ram

📎 MegaMek.l4j.ini

#

Im also launching with jar on windows but that should not be an issue

sly grotto Dec 14, 2024, 6:07 PM

#

that is probably the issue think you would need to pass in these as parameters

polar scaffold Dec 14, 2024, 6:08 PM

#

Which parameters

#

?

sly grotto Dec 14, 2024, 6:08 PM

#

the ones in the ini file

polar scaffold Dec 14, 2024, 6:09 PM

#

So what should I do, run with exe instead ?

sly grotto Dec 14, 2024, 6:10 PM

#

run MegaMek.exe

#

or MekHQ.exe

polar scaffold Dec 14, 2024, 6:12 PM

#

Ok, and keeping updated ini files you gave me

sly grotto Dec 14, 2024, 6:13 PM

#

the exe file uses the ini file adjust the java parameters

polar scaffold Dec 14, 2024, 6:15 PM

#

what is the name of java's "ini files" ?

sly grotto Dec 14, 2024, 6:22 PM

#

MegaMek.l4j.ini and MekHQ.l4j.ini

polar scaffold Dec 14, 2024, 6:29 PM

#

I am confused I already edited those ones, and you said they only affected the exe version. So how can I fix the jar version ?

sly grotto Dec 14, 2024, 6:29 PM

#

not sure how to fix running for the jar. I was just explain how the exe works

polar scaffold Dec 14, 2024, 6:30 PM

#

Ok I will stick to exe version

frosty fossil Dec 14, 2024, 7:18 PM

#

The EXE versio is the JAR version but the stuff in the INI file gets appended into a single line and passed to the JAR version.

#

The EXE is just to make it easier for Windows users. Same with the shell scripts for Linux users.

sour isle Dec 14, 2024, 9:58 PM

#

basically the equivalent of a batch script

polar scaffold Dec 14, 2024, 10:45 PM

#

frosty fossil The EXE versio is the JAR version but the stuff in the INI file gets appended in...

So basically the jar is the vanilla version and the EXE is the jar version plus instructions coming from ini ?

frosty fossil Dec 14, 2024, 10:49 PM

#

polar scaffold So basically the jar is the vanilla version and the EXE is the jar version plus ...

The EXE is in essence a shell script with some fancy additions such as JRE checking, copyrights, app icons, support URLs, etc for WIndows. it does nothing but load the JAR using the command line args within the INI.

#

It's all the same version, just a different way to load it

polar scaffold Dec 14, 2024, 10:50 PM

#

Oh ok, so launching via jar is the more direct way to do it

#

But since I need ini files to fix artifacts, I will not be able to fix the jar version or is there a way ?

frosty fossil Dec 14, 2024, 11:01 PM

#

You can do the Jar version if you pass the same arguments to the java run time before the -jar command.

#

That's all the EXE is doing.

polar scaffold Dec 15, 2024, 8:12 AM

frosty fossil You can do the Jar version if you pass the same arguments to the java run time b...

I am still new to JRE, where do I add those arguments ?

frosty fossil Dec 15, 2024, 12:38 PM

#

java <arguments> -jar MegaMek.jar

polar scaffold Dec 15, 2024, 1:56 PM

#

Ok so in my case I need to go to the shell and run the following command :
java -Xmx8192m -Dsun.java2d.d3d=false -jar MegaMek.jar

frosty fossil Dec 15, 2024, 2:48 PM

#

If you want to run from the shell, yes.

polar scaffold Dec 18, 2024, 4:21 PM

#

📎 message.txt

#

Managed to make both java2d commands work

#

These are the error messages responsible for the weird duplicates, does someone have a fix ?

#

I am using a .bat file of this content :

cd "C:\Users\myself\Documents\myGames\MekHQ-0.50.01"
java -Xmx8192m -Dsun.java2d.d3d=false -Dsun.java2d.noddraw=true -jar MegaMek.jar
