Performance Guide
There are a lot of factors that can cause performance issues in your game, the most notably is that you have not set enough RAM for the Modpack. Below is a guide to help you get the best performance out of the Modpack as possible!
This should fix most of your Performance Issues
We also recommend increasing the amount of RAM Minecraft has. Minecraft is a very memory hungry application, and mods make it even more so.
(If you already know how much RAM your PC has, you can skip 1-3)
- Open Task Manager (Ctrl + Shift + Escape)
- Go to the Performance tab at the top
- Find the number under Memory (For example 5.8/7.9GB means your device has 8GB. 7.4/15.9GB means you have 16GB)
If you have 12GB or more, allocate 8000MB of RAM to Minecraft. If you have 8GB, allocate between 5000MB and 5500MB of RAM to Minecraft.
For ATLauncher launchers, a Google/YouTube search should help, or you can ask here.
IF you want to allocate more than 8000MB then we recommend not allocating more than 12000MB
We don't recommend the use of CurseForge launcher. This is due to the fact that historically, many users have had trouble with CurseForge incorrectly installing the modpack, causing bugs and unintended behaviour, and breaking not only the modpacks but the launcher itself (if you want to see evidence of this, please take a look at the announcements channel in LPS discord). CurseForge also bundles itself with Overwolf, a bloatware program that uses up a lot of performance on your PC, which can inadvertently affect Minecraft's performance as well.
To remedy this, we recommend users switch to either ATLauncher GDLauncher. Both launchers have proven to be more reliable, with ATLauncher being the most reliable launcher. Both have significantly better reliability and overall better performance when running our modpacks.

If you are still experiencing lag
Press F3, in game in a world, on your keyboard and check the percentage next to "Memory:". If it shows your game is using most of the RAM you've allocated, feel free to allocate more (With a max or 12GB Allocated). Try not adding too much, as Minecraft can sometimes perform worse with too much ram. Also, make sure you leave 2-3 GB for Windows to run - otherwise your game performance will decrease.
Tweak some video settings
There's a few settings you can change that should overall not affect the modpack in any way, while also improving FPS.
- Render Distance: Bump this down to 8 or even lower if you need to. Do note this will reduce the overall amount of blocks and entities you can see, so try to experiment with it and find a tradeoff.
- Simulation Distance: Always recommended to push down to the lowest value. This reduces the overall chunks around you that tick (update for things like crop growth, redstone, mobs, etc), but its still large enough that you probably won't notice it. If you do notice some things stop working, first try and see if you can force-load those chunks before reverting.
- Particles to Decreased: Fairly straightforward. Decreased will NOT remove any particles, it will simply reduce the amount rendered. This can often improve performance heavily, especially in areas with a lot of particle effects.
- Entity Distance: The default at 100% renders entities up to 10 chunks away. Most players don't often need to see mobs from so far away, so you can safely turn this down to either 75% or even 50%.
Close Programs
If your Memory is at high usage and Discord, Google, Overwolf, Curseforge, or other programs which are using lots of memory are open, close them via task manager (Press CTRL + Shift + Escape.) Just be sure not to close anything essential for your computer to run.

Setting Minecraft to high priority can result in minor FPS improvements. A tutorial can be found here https://www.youtube.com/watch?v=j1Rtd8JiClA
Disabling Hardware-accelerated GPU scheduling reduces latency and stuttering and increases FPS across all games. To do this, press the Windows button and search Graphics Settings. On Windows 10, simply turn the switch off. Windows 11 requires a few extra steps - click the blue text.
