Ultramodern optimization pays attention to the smoothness and stability of the game in various environments. While pursuing a high number of frames, it also carries out a more comprehensive test: compatibility, tps optimization, network optimization, and speeding up the startup speed. In order to ensure a smooth play. This is the result of proper matching of integration package modules, and some newer optimization modules are selected, which is the origin of the name of integration package-ultra-modern optimization actually uses both modern repair and modern UI, huh?

Unlike typical optimization packs—which usually select generic, unremarkable optimization mods—Ultra Modern Optimization adopts an integrated optimization system. The author provides a preset suite of optimization mods, most of which are suitable for inclusion in client-side modpacks.

Version 2.5.2: Provides detailed mod compatibility.

Provides a more detailed introduction and settings. 

Provides more perfect optimization presets. 

Provides configuration file modifications.

Tips: The optimized module can only schedule the remaining performance of hardware better than the original, and the improvement effect may even be accompanied by negative optimization due to different hardware. The purpose of this optimization package is to obtain a smooth game experience in a multi-module environment and a local host environment. If it is a pure client or an original player, a simple collocation of lighter mainstream optimization modules such as Embeddium dium on forge may be enough. As we all know, almost only sodium can greatly improve the frame number of the original version in the optimization module, and the collocation of more optimization modules is to obtain the same stable frame number as the original version in the multi-module environment (at the same time, the author actively compatible and made the integrated package of the optimized version). The following are the tests in the original 1.20.1forge: Test configuration: Intel i7-4710HQ (4 cores, 8 threads, 2.5GHz)+NVIDIA GTX 860M (independent display) with FHD(1080P) resolution. Original setting: Render distance 8 blocks, turn off vertical synchronization and simulate distance 5. The original version is close to 100FPS, and after using the optimized package, it is 350FPS, which is improved by nearly 250%.

Frequently asked questions Q: Can it be put into the integration package for optimization as the optimization bottom package, and what is the effect? Yes, the optimization in this package is very comprehensive. The integration package is biased towards gameplay expansion, and the optimization may not be considered well. The reason may be that the authors of the integration package have better configuration and there are differences, and it is not considered that adding optimization modules is suitable for everyone. (In addition, the author is also actively providing optimization to the author of the integration package, which can be viewed on the author's home page.) Q: Why will there be negative optimization after joining the WTO? By default, the optimization in the package is aimed at the local host and covers a wide range. If it is a pure client or server, adding the optimization package directly will introduce many unnecessary optimizations, which will only have negative optimizations for devices with low configuration. You can choose lighter optimizations instead of being greedy. Q: As a base package, it is compatible with other integration packages. Compatible with most integration packages, but pay attention to eliminating duplicate optimization. Q: Game crash or game experience problems. Please attach the report error log and the rational feedback of the module package environment. express one's thanks/gratitude The optimization effect of the integration package can not be separated from the module contributions of community module authors, as well as the tests and suggestions of their authors: Awei, Argon4W, etc., and many other people.

Known compatibility issues:

1. Optimization Pack v2.4 for Minecraft 1.20.1 Forge is confirmed compatible only up to Forge loader version 47.4.0. Other Forge versions are not guaranteed to work (loader version can be ignored).

2. Starlight is incompatible with Create mod versions newer than 0.5.1j. Removing Starlight resolves the issue if using Create 0.5.1j or later.

3. Create versions newer than 0.5.1j may conflict with Radium, causing crashes. Removing Radium resolves this.

4. Potential incompatibility with XinYa Interconnect mods. Removing Despawn Tweaks, txnilib, Cerulean, and Redirected resolves the issue.

5. Incompatible with Twilight Forest and possibly other mods. Removing "c2" resolves this.

6. Incompatible with GPUs/drivers supporting OpenGL 4.6 or lower. Disabling accelerated rendering resolves the issue.

7. If crafted items don’t appear in the crafting grid but can still be crafted, removing "Workbench Performance Optimization" fixes it.

8. If additional Cataclysm structures cause crashes, remove Radium. If fishing triggers an achievement-related crash, remove Flerovium.

9. If Ars Nouveau crashes occur, disable Rhenium’s “Asynchronous Particle Logic” in its config.

10. Adding Alchemistry v1.1.3 may cause crashes; upgrading to v1.1.6 resolves this.

11. After entering a new dimension, Thaumcraft’s grimoire may occasionally stop working—spells and enchantments won’t display until you re-equip the grimoire. Similarly, spells applied via the Arcane Anvil to armor may disappear from the spell wheel until the armor is re-equipped. (No current fix, but the issue is minor.)

12. Optimization mod Cerulean is incompatible with Icterine—remove Icterine (functionality overlaps).

13. If the optimization mod Ixeris frequently crashes the game, remove it.

14. If the optimization mod Gnetum causes screen flickering, remove it (can be ignored if performance gain is prioritized).

15. In Optimization Pack v2.5 for 1.20.1 Forge, the mods “Recipe Performance Optimization” and “Recipe Essentials” are no longer compatible—remove them (functionality overlaps).

16. The optimization mod “Better Foliage Reworked” is disabled by default. It can be enabled via the Embeddium (Emb) settings menu. (Enabling it should not significantly reduce foliage visual quality, even at quality level 1.)

17. Embeddium+ is disabled by default. It can be enabled via the Embeddium (Emb) interface—only enable “JEI hidden items: show only in search”; avoid changing other settings.

18. Freezing Issue: If you encounter the game freezing on the loading screen or getting stuck on a black screen, you likely have an incompatible mod. Try removing optimization mods of similar functionality—or specifically delete: Despawn Tweaks, txnilib, Cerulean, Redirected, or Ixeris—and test again. (Remember to add Icterine as a replacement optimization mod.)

19. Optimization Mod: TT20 is currently flagged as unstable for single-player on Forge 1.20.1, so it won’t be included in version 2.5 of the pack. You may still add it yourself, but note that it may be incompatible with mods that enhance or extend visual effects. Solution: Remove TT20 if conflicts arise.

20. Optimization Mod: The mod "Save My Shitty Network" (SMSN) may trigger an error labeled "SMSN". Solution: Remove "Save My Shitty Network" to resolve the issue.

21. **Crash/Freeze Issues:  
- Type 1: Stuck on the launch screen without reaching the loading screen.  
- Type 2: Stuck on the loading screen and unable to enter the game client.  
Both are typically caused by conflicts among optimization mods. Please carefully review your optimization mods for compatibility.

22. Optimization Mod: Quick Recipe Lookup & Chisel Stone is incompatible with recipes defined via CraftTweaker, which may cause incorrect enchantment readings. (This usually doesn’t break gameplay.) However, if recipe exchanges stop working entirely, removing the mod will fix the issue.

23. Network Optimization Mod: Packet Fixer resolves some issues but can introduce others. If you're unable to connect to multiplayer servers, try removing Packet Fixer and test again.

24. Optimization Mod: Chloride (Embeddium++/Sodium++) may cause crashes due to its outdated version in the current optimization pack. Solution: Either upgrade to a newer version or disable it.

25. Regarding Chloride (Embeddium++/Sodium++) Usage: Most features in the included Chloride version are disabled by default. If you wish to enable something, it’s recommended to only turn on “Item Manager – Hide Unless Searching”, which you can find under EMB’s Performance settings (scroll down).

26. Why MCreatorMemFix Isn’t Included: MCreatorMemFix is a memory-fix mod specifically for MCreator-generated content. However, if other mods also modify the same underlying files, compatibility issues may arise. Since it’s a *specialized* fix, it won’t be bundled into the optimization pack by default—**but you can add it manually if needed.

27. Shaders/Rendering Optimization Mod: RenderScale may conflict with other shader-related mods. Do not modify it if your setup is already working. Compatible configurations are currently under testing (default settings are applied for now).

28. All-in-One Optimization Framework:  
⚠️ Warning: Risky Operation! Back up your pack before attempting!⚠️  
The author highly recommends deleting all optimization mods from your current modpack and replacing them entirely with the mods and config files from this optimization pack**. Some duplicate optimization mods can be kept or removed (use PCL CE to identify duplicates). This method is highly efficient—but proceed with caution and always back up first!

Question: Were configuration files modified? Can I import this pack into my existing modpack?

Answer:  
Yes, the optimization pack includes extensive modifications to config files and implements aggressive fixes for several issues. You must import the config files from inside the provided config folder into your own modpack’s config folder (be careful not to import the wrong folder). Do not arbitrarily add optimization mods from this pack into a modpack that doesn’t include the corresponding config files—doing so may cause immediate crashes.
