This is all in-game test in PvP Club Duels while on 1.21.11 of this modpack. Going to singleplayer or going to other modpack versions (Like 1.21.4) has and will raise FPS greatly. Also using 26.2 with Vulkan can greatly raise FPS on high end systems.

• System 1: Intel i7-7700T, IGPU, 8GB DDR4 - 190 FPS.
• System 2: Intel i3-N305, IGPU, 8GB DDR4 - 230 FPS.

• System 14: Ryzen 7 7800x3D, 4070 Super, 32GB DDR5 - 1170 FPS.
• System 15: Ryzen 9950x3D, 5090, 64GB DDR5 - 1770 FPS. (System used for gallery images)
• More to be added. volunteers allowed!

All benchmarks are real results performed by actual actual people, some benchmarks were taken on later versions of the modpack so benchmarks FPS may be lower then what it actually is.

Resource packs are much more reliable compared to mods. Use when possible. When using a mod, the mod adds startup time, possible issues in the future, and sometimes cause performance problems. Resource packs are much more lightweight and can do much most visual mods can do anyways. To make a simple pack you can use Vanilla Tweaks. You should look for a resource pack before adding your visual mods like BactroMod.

Do /Visiblebarriers fullbright true. If not working in public servers, turn up brightness in sodium settings to max, then if still not working you can turn off smooth lighting in video settings/quality. If nothing works past this, revert your settings and just enable Gamma Utils.

First make sure particles is not set to minimal in video settings/quality. If set on decreased or all and still not showing you can go to video settings/particals and manually enable/disable your choice of particals. Same for animations, go to video settings/animations and select your choices.

First, If you select wrong Java Arguments for your PC or is just incombatible, this can cause some crashing. Second, Make sure you did not add any more mods outside of what comes in the pack. If nothing changed then read the fabric message or read the crash log. If hard to understand you can just ask a friend or send it to a clanker to read. Third, If you cant get a clear answer simply install Crash Assistant then when it crashes read the logs it gives. If you still dont understand the logs you can forward it to the Crash Assistant Discord and get help from someone who understands minecraft modding well. Finally, if your issues are specifically with this modpack please report crash logs/any helpful information so I can personally try to fix for future versions. If you do not know where to put the logs please go to the Report Issues link.

If you see a error like this:

Simply add ( --add-modules jdk.incubator.vector ) to your Java arguments.
