Post install
This page contains a few things you can do after installing Adrenaline to get better performance, better stability, etc. Some mods are already configured well enough to get improvements, so this guide will not include information about those. Depending on your system, you may or may not see an improvement, however on low-end systems you should notice an improvement. Some parts of this page were inspired by the Simply Optimized wiki.
There are some ways to improve your performance past installation. Some of them are experimental and should only be used if you really want to.
Nvidium is a replacement rendering backend for sodium that uses Nvidia-only OpenGL extensions to increase FPS by a significant amount. This mod requires an Nvidia GPU that supports mesh shaders - a feature that was introduced in the Turing microarchitecture, which means this mod will work with any GPU that is 16xx series or newer. If you are on an unsupported GPU, the mod will automatically disable itself and your gameplay will not be affected. This mod is currently in a beta state and may, in rare cases, cause Minecraft to unexpectedly terminate. I plan on adding this mod to Adrenaline in the future once it's considered stable enough for general use.
C2ME is a mod designed to improve chunk performance using multi-threading. While on some systems this can increase chunk generation speeds and possibly improve framerates, the mod itself is an alpha and can be unstable at times - possibly, in rare cases, causing world corruption. If you don't care about the mod being experimental, you can install it manually after installing this modpack. The mod is already pre-configured by Adrenaline. Keep in mind that C2ME can possibly increase resource usage.
Exordium aims to render the GUI and screens at a lower framerate to speed up world rendering. This is not included in Adrenaline due to possible mod conflicts and because it can make performance worse on GPU-bottlenecked setups. If you're CPU-bottlenecked and don't have any mod conflicts, consider checking this mod out.
This is an add-on to Sodium that adds some extra configuration settings for Sodium. It does not improve performance by itself, but it allows you to control various graphical effects such as particles and animations, which could improve performance at the cost of visuals. This is already included in Additive.
Methane completely removes the lighting engine from the client. This results in a major performance boost, however it does make the game look way worse as it removes the lighting engine :p If you don't care about visuals and just need the best performance, consider checking this out.
Before setting your memory used by Minecraft, you should first check your system's memory. To see this on Windows, open up Task Manager, go to the performance tab, and under "memory" you should see the amount you have installed on your system.
Allocating more memory to Minecraft may increase performance greatly, but setting it too high can cause issues as well. If you have a low amount of memory installed, please make sure to keep enough memory for your system. As a general recommendation, 2-4 GB (2048-4096 MB) is usually all you should use for bare Adrenaline/Vanilla. Playing with many mods? I'd suggest 3-6 GB (3074-6144 MB), however you may set this lower if needed. Do what works for you. Never set your allocated memory to the same amount as your installed memory.
In Prism Launcher, you can set your memory by going to Settings > Java > Maximum memory allocation. You may set the minimum memory too, however I haven't noticed any improvement over using the default.
By default, Adrenaline does not change any of Minecraft's quality/graphics settings, except for simulation distance which will be explained later.
Start by changing your render distance. The higher this number, the further you can see. If you are playing on multiplayer, servers usually have a cap for render distance. On low-end systems, this should be set to 4-8 chunks. Mid-range systems will usually work well with 8-16 chunks, and high-end systems should be fine with 12-24 chunks.
After this, you can change your simulation distance. This is the distance in chunks that entities, blocks, fluids, etc are ticked, meaning that things like farms outside of this distance may not work properly. Unless you have areas with big farms and such, the default 5 should work well. If not, use 8-12. This only affects singleplayer - you won't notice anything while playing on servers as they have their own setting for simulation distance.
I recommend keeping V-Sync turned off unless you notice screen tearing, which in that case, turn it on or use Adaptive V-Sync. To use Adaptive V-Sync, you will need to install the Sodium Extra mod. If you are using Additive, this mod is already included. Adaptive V-Sync typically has less input latency than normal V-Sync.
Set graphics quality to "fast" on low-end systems and "fancy" on mid-range to high-end systems. This will affect if leaves are transparent or not, weather particles, and other things. Do not use Fabulous unless you absolutely need it's benefits, as it can have a noticeably negative impact on performance.
Set particles to "minimal"/"decreased" on low-end systems, and "all" on other systems. For greater control over particles, install Sodium Extra.
Warning This part is generally meant for advanced users! If you don't understand how to do this, then you should ignore this and stick with what you have now. I will not offer support for setting this up.
Tuning the JVM can be a good way to improve performance for some people, especially server-side. Follow along with this page for some more information about this.
First, you can get Sodium Extra. This mod lets you configure extra graphics options and also add an FPS counter in the corner of your screen. Next, get Reese's Sodium Options. This mod improves the experience and looks of the Sodium menu. If you are using Additive, both of these are already included by default.
To get support for shaderpacks, install the Iris Shaders mod and then go to the Video Settings menu. If you are using Additive, this is already included by default.
If you want to play immersively on VR, the Vivecraft mod exists for that. View vivecraft.org for more information on how the mod works and how to use it.
