40-50% more FPS in MECCHA CHAMELEON, with the same look.

Almost all of the game's graphics cost comes from two settings: Lumen's global illumination and

reflections on Epic. Chromium holds those two at High. The bounce light and reflections are

worked out at a lower resolution and then smoothed, so side by side the picture looks the same.

| Measured on an RTX 5060, Epic settings, in the lobby | 2560x1440 | 1920x1080 |

|---|---|---|

| The game as it ships | 81 FPS | 121 FPS |

| With Chromium | 120 FPS | 173 FPS |

| 1% lows | 77 -> 111 FPS | 111 -> 143 FPS |

Every other setting was tested too: hardware ray tracing, volumetric fog, motion blur, shadows and

post-processing each made under 3% difference. Chromium leaves them alone, so nothing else looks

different.

Also: "unlimited" really is unlimited

With the game's frame-rate limit set to unlimited, the engine falls back to its smoothed frame rate,

which stops at 62 FPS. With Chromium on, unlimited means unlimited (handy on a 144/165 Hz

screen). Any limit you pick in the game's options is kept as it is.

Good to know

  • Only your game changes. Nothing is sent to anyone, so it works on any server, hosting or not,

and other players don't need it.

  • Your saved settings are never touched. Chromium changes the settings while the game runs and

never writes them to disk.

  • Settings already at High or lower are kept. If you change graphics in the game's options

while Chromium is on, that becomes your new choice; Chromium only steps Epic down to High.

  • F7 switches Chromium off and on in the game, so you can compare. A small card at the top

right says what it's doing. It starts on each time the game launches.

Install

With a mod manager ( Mod Manager / r2modman): install Chromium. Its dependency, the

MECCHA CHAMELEON UE4SS package, comes with it.

By hand: install UE4SS's experimental build for Unreal 5.6. Then copy the mod folder from this

package into UE4SS's Mods folder and rename it Chromium, so you end up with

Mods/Chromium/enabled.txt and Mods/Chromium/Scripts/main.lua.

To uninstall, remove the mod. Your settings were never saved, so the next launch is exactly as before.

Made by

Reagent Launcher. Chromium also ships with Reagent Launcher, where it's an Off/On switch in the

Performance section.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
