About this Modpack
How to Install
To install the modpack, go to the Files tab and select the version you want to install. Feel free to add any mods to this pack to have the best time possible. Any versions marked with "Alpha" or "Beta" are still being tested and may lead to game crashes. Be sure to only use the public release version to have the best time possible without any crashing.
Short Summary
This is just a little modpack I have been putting together for the past few months or so. It all started when I was having issues with lag and stuttering on a less than average machine. With the combination of mods I have compiled, you should have little to no issues getting a decently high framerate on a less-than-average PC
Contents (Short Version)
This pack includes:
Cracker's Witherstorm
Viner
and other quality of life mods
The Brains Behind It (Contents Pt.2)
Using the Sodium Renderer, you will have a potential of up to 500+ FPS
Viner allows you to mine ores quickly (in this case to escape the Witherstorm)
Immediately fast allows you to not have that many lagspikes during play
Creative Core combined with EnhancedVisuals allows you to fully be immersed by the damage you recieve (in this case from the storm again) HAD TO BE REMOVED, MUST BE ADDED YOURSELF
EntityCulling hides mobs that don't need to be there
+compatibility with any of your own mods!
How this pack works (singleplayer, multiplayer, lag, etc.)
If you have been having issues with lag, freezing, or stuttering then this pack is for you. This pack should make you have a very easy time running the Witherstorm Mod, all the while having the best time on multiplayer or singleplayer. The extra mods I have added also have little to no extra lag. (Note: in my testing I have seen it works BEST with 2-4 people. May cause lag or other problems. Also only add any extra mods knowing that it may cause more lag.)
Bug Reporting
If you find any bugs, please contact me and send me the error code the Minecraft Launcher give you so I can try and sort out the bugs as soon as I get the chance. I will try yo have my messaging inbox open or can provide an email for any further support.
Good luck and have fun slaying the Legendary Witherstorm! :D

Yes, but check compatibility: only use mods for the same loader (forge) and same Minecraft version (1.20.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
