Hardly Optimised
best optimisation modpack to exist.
⚠️ Critical Warning: Minecraft 1.21.7 Unsupported ⚠️
All versions between 1.21.6 and 1.21.7 suffer from severe problems on Intel GPUs (Mojang-confirmed bug). This is NOT Hardly Optimised's problem, this is a problem in minecraft that i cannot fix.
This is not optional if you use Intel UHD or any low-end system, continuing use of these versions may corrupt worlds or constantly crash.
About
Hardly Optimised is a modpack made for 1.16.5-1.20.1-1.20.4-1.21.x-26.1.2-26.2 that is made with one goal in mind: to be very stable and performant. See, unlike other optimisation modpacks this one isn't bloated with 200 mods you're probably never using in your life or using 2 of the mods there at best, or made poorly where it does get a lot of fps but crashes every 5 minutes. Hardly Optimised focuses strictly on stability and making FPS make you feel like you have a RTX 5090.
FAQ

Q: Does this replace OptiFine?
A: Yes. This pack gives significantly higher FPS than OptiFine and has almost every OptiFine feature.
Q: Can I add my own QoL / gameplay mods?
A: Absolutely! Hardly Optimised is an optimisation modpack and was purposly made to be as comatible with mods as possible, so you can add whatever mods you like on top.
Q: Is this mod compatible with lunar client?
A: Yes, it should. There is no mod in this modpack that breaks lunar client in some way for it to not be compatible.
Recommended Settings
-
RAM Allocation: Allocate 2GB to 4GB of RAM. For example, if you have 8GB of total RAM, allocating half (4GB) works great. However, if you are rich and have 16GB of RAM or more, do NOT allocate half (8GB+), allocating too much RAM will actually cause lag spikes due to Java Garbage Collection! Stick to 4GB max.
-
Graphics Settings: You should usually leave these as they are. The pack is already tweaked to give you max FPS right after installing it.
