[UO]Ultramodern optimization
Smooth Gameplay, Engineered to Perfection
Quick answer
Which [UO]Ultramodern optimization release should I use?
[UO]Ultramodern optimization-2.5.6 is a complete pack release for 1.20.1 with Forge 47.4.16. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 26 mods in this pack file.
Pack setup
How should I set up [UO]Ultramodern optimization for players and a server?
Use [UO]Ultramodern optimization-2.5.6 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for [UO]Ultramodern optimization?
[UO]Ultramodern optimization-2.5.6. Change the pack release and its contents or setup may change too.
The selected pack release is [UO]Ultramodern optimization-2.5.6. That file is for Minecraft 1.20.1 with Forge 47.4.16. It contains 26 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
About this project
What kind of pack is [UO]Ultramodern optimization?
Smooth Gameplay, Engineered to Perfection
中文版
Ultramodern Optimization features several highly customizable optimization configuration presets, allowing you to adjust settings based on personal needs in different scenarios. You can also manually disable unwanted mods within the DLC Manager to better tailor the modpack to specific requirements. The modpack includes a built-in new categorization system and offers a one-click option to enable server-side optimizations within the presets.
Precautions
Ultramodern Optimization's default modules are sufficient for small modpacks. For large modpacks, you may need to manage settings within the DLC Manager or enable relevant optimizations in the presets.
Friendly Reminder: Optimization mods can only better utilize remaining hardware performance compared to vanilla; their effectiveness varies by hardware and could even result in negative optimization. The purpose of this optimization pack is to provide a smooth gaming experience for players in local multiplayer/modded environments. If you are a single-player client or a vanilla player, simply combining lighter mainstream optimization mods like Embeddium might already be sufficient.
In the new version of the Forge 1.20.1 2.5 modpack, the client itself is already highly lightweight and compatible with most modpacks. If you need to adjust settings in the DLC Manager, you should pay more attention to compatibility issues!
As is well known, Sodium is almost the only optimization mod that significantly boosts vanilla framerates. Combining more optimization mods aims to achieve stable framerates in multi-mod environments comparable to vanilla (meanwhile, the author is actively working on compatibility and creating optimized versions of modpacks).
FPS Improvement
The following tests were conducted in 1.20.1 Forge:
Test Configuration:
CPU: Intel i7-4710HQ (4 Cores, 8 Threads, 2.5GHz)
GPU: NVIDIA GTX 860M (Dedicated Graphics)
Resolution: FHD (1080P)
Vanilla Settings:
Render Distance: 8 chunks
V-Sync: Off
Simulation Distance: 5 chunks
Results:
Vanilla: Approached 100 FPS.
With Optimization Pack: Reached 350 FPS.
Improvement: Approximately 250% increase.

Vanilla: Unoptimized

Optimization Presets
Most optimization packs simply select mods for optimization without any unique features. However, in Ultramodern Optimization, the author has adopted an integrated optimization system, and the package includes several optimization configuration presets. Most optimization mods can be incorporated into modpack clients.
For 1.20.1 Forge (Optimization Pack version 2.5.2): Detailed mod compatibility is provided.
