RGB software that won't slow your PC down

Most RGB apps run all day in the background, one for every brand, and some are known to cause stutter in games. RGB Engine lights your whole case from one small app that uses about 15 MB of RAM.

Coming soon to Steam. We'll email you when it's out.

Built to stay out of your games

Your lights run on a tiny background engine that uses well under 1% of your CPU. The window only opens when you want it, and closing it leaves just the lights running.

RGB Engine
About 15 MB, 2 processes
SignalRGB
~1.5 GB, 13 processes

Task Manager's Memory column on the same 16-thread gaming PC: RGB Engine itself uses 1 to 5 MB, and OpenRGB, which talks to your hardware, 4 to 11 MB. Windows trims both when they sit idle, so you'll often see less. Full comparison

One app instead of one per brand

Your motherboard, RAM and fans can each come with their own lighting app, and they all start with Windows. RGB Engine lights all of it from one place, so the rest can go.

  • Motherboard RGB headers
  • ARGB fans
  • RGB RAM
  • LED strips
  • AIO coolers

Works through OpenRGB, which comes included. Full supported hardware list. Your mic, keyboard and mouse are left alone unless you switch them on.

Lighter, and it looks better

Over 100 looks, each one designed, not just rainbow waves. When music plays, bass hits the fans, mids the cooler and strips, and highs the RAM, so the whole case plays along. Try one here, or build your own in the editor.

Simple enough for anyone

Pick a look and you're done. Favorites, the editor and the settings are there when you want them, and out of the way when you don't.

The RGB Engine library: the current look shown live on fans, strips and RAM, with palettes and shelves of looks below.

The RGB Engine scene editor: layers like Sky and Aurora on the left, each aimed at fans, cooler and strips or RAM, with a live view of the case on the right.

Set up in about two minutes

Or skip it and start with a sensible default. You can run it again any time.

  1. List your parts

    Fans, cooler, RAM, strips. You say what's in the case, not which header it's on.

  2. Watch each one light

    It lights every part by name so you can confirm it found the right one.

  3. Leave it alone

    The map gets saved. Every look knows where everything sits from then on.

Questions

Will RGB Engine slow down my PC or games?

No. While your lights run, RGB Engine uses about 15 MB of RAM and well under 1% of your CPU, measured on a 16-thread gaming PC. The window only uses more while it's open, and you can close it and keep the lights running.

Can RGB software cause stutter in games?

It can. Players have traced microstutter to RGB apps that wake the CPU in short bursts to animate their lights, often several apps at once. RGB Engine runs every light from one small background engine at a steady pace, using well under 1% of the CPU. How to check your PC

Do I need an account or a subscription?

No. You buy RGB Engine once on Steam. There's no account, no subscription and no ads, and the app doesn't send anything off your PC.

How much does RGB Engine cost?

RGB Engine will be $4.99 on Steam. Join the waitlist and we'll email you the day it comes out.

What hardware does it work with?

Most motherboard RGB headers, RGB RAM, LED strips, coolers and lots of other gear. RGB Engine talks to your hardware through OpenRGB, which comes included, so anything on OpenRGB's supported device list works.

How is it different from SignalRGB, iCUE or Armoury Crate?

One app covers your whole case instead of one app per brand. And it's light: on the same PC, SignalRGB ran 13 processes and about 1.5 GB of RAM, while RGB Engine ran on about 15 MB.

Do the lights react to music?

Yes, to whatever's playing on your PC. Bass drives the fans, mids drive the cooler and strips, and highs sparkle the RAM. How it works

Can I make my own lighting?

Yes. Remix any of the 106 looks or build your own in the scene editor: stack effects like aurora, fire and lightning, pick colors, set the speed and choose which parts of your PC each one lights. You can export scenes to share them.

Will it mess with my mouse, keyboard or mic lighting?

No. RGB Engine leaves mice, keyboards, headsets and mics alone unless you switch them on, so things like a mic's mute light keep working.

What do I need to run it?

Windows 10 or 11 (64-bit), 4 GB of RAM and RGB hardware that OpenRGB supports.
