Our notes on Keo Optimized

What sets it apart

Keo Optimized is a small performance pack. The project page says it holds only proven optimization mods, with no extra content or features, so the game keeps its vanilla feel. The author aims it at low-end PCs and laptops.

The mod list for the newest build includes Sodium, Lithium, ImmediatelyFast, ModernFix, ScalableLux and Iris. What stands out is the shader side: the list also carries several shader packs, including Complementary Reimagined, BSL, Photon and Solas. Most optimization packs leave shaders out, so this one is closer to a performance base with a few visual options already present.

The page promises higher frame rates, less stutter, faster loading and better stability. It gives headline frame rate multipliers, but no benchmark conditions are published, so this note does not repeat them.

Who it suits

It fits players on weak hardware who want vanilla gameplay and would like to try shaders without assembling the mods themselves. It is not a content pack, so it adds no blocks, mobs or systems.

Before you install

Version coverage is wide. Modrinth lists Minecraft 1.20.1 through 1.21.11 and the 26.x line up to 26.3. Most builds are Fabric. The version list shows two Forge builds, both for 1.20.1, and one NeoForge build for 1.21.1, so those loaders are covered for one game version each, as of this writing.

The Modrinth description describes the pack as a Fabric pack and does not mention the other loaders. Check which file you are downloading before relying on it.

No RAM recommendation is published. The pack is CC0 licensed.

Playing with friends

Modrinth marks the pack as required on the client and optional on the server. The page text does not spell out what that means for servers.

No server pack is published. The mod list is mostly rendering and performance mods, which mainly affect the machine running them, so each player would install the pack on their own PC to get the same setup. Whether mixed setups cause problems is not documented.
