We all know it. Unreal Engine and Unity can crush a local machine the second your scene gets ambitious. You know the moment. The fans spin up, the frame rate tanks, and suddenly that high-fidelity experience you worked so hard on becomes a slideshow.

That’s where Pixel Streaming changes the game. It’s a technology that lets you render your project on powerful cloud servers and stream the output, as pixels, not files, directly to any device. Your end user gets the full-quality, real-time experience you intended. And their hardware? It barely breaks a sweat.

In this guide, we’ll break down what Pixel Streaming actually is, how it works under the hood, and where it fits into modern workflows. We’ll cover real examples, challenges to watch out for, and smarter ways to implement it — whether you’re showcasing an architectural model, running a multiplayer game, or presenting an interactive product demo.

If you’re exploring Pixel Streaming for Unreal or Unity, or just tired of fighting hardware bottlenecks, you’re in the right place.

What is Pixel Streaming?

Pixel Streaming is exactly what it sounds like, streaming pixels. Not code. Not files. Just the raw frames, rendered in real-time on a powerful server, sent straight to your device over the internet.

Think of it a bit like remote desktop, but built for high-performance graphics and real-time interaction. Instead of your machine struggling to render that dense Unreal Engine scene or complex Unity project, a cloud GPU does the heavy lifting. Your device? It just displays the finished result, almost instantly.

Here’s the core idea:
👉 The user sends input (a click, a keystroke, a controller move).
👉 A cloud server with a GPU renders the next frame based on that input.
👉 The server compresses and streams that frame as a video feed (using formats like H.264, H.265, or AV1).
👉 Your device decodes and displays the frame.

Because the frames are rendered on the server, Pixel Streaming lets you deliver demanding 3D apps, VR experiences, or interactive visualizations to almost any device, even low-power laptops, tablets, or phones.

And it’s not just about hardware savings. Pixel Streaming makes it possible to run Unreal or Unity apps inside a browser without the user needing to install or download anything. That’s a game changer for interactive product demos, architectural walkthroughs, virtual events, and cloud playtesting.

How Pixel Streaming Works?

At its core, Pixel Streaming is all about speed, taking your input, rendering the result on a cloud GPU, and getting those pixels back to you fast enough that it feels like you’re working locally. Simple in theory. Tricky in practice.

Let’s break it down step-by-step so it’s easy to picture:

1️⃣ Your Input Gets Sent to the Server

When you click, type, drag, or move a controller, that input doesn’t stay on your device. It’s instantly sent over the internet to a remote server, usually one with a high-end GPU (NVIDIA RTX, for example) sitting in a data center.

👉 In my experience, this is where latency starts to matter. The closer the server is to the user, the snappier everything feels.

2️⃣ The Server Renders the Next Frame

The cloud server receives your input and uses it to compute what the next frame should look like. This is where your Unreal Engine scene, Unity app, or 3D experience actually gets rendered, using all that GPU horsepower.

Whether it’s dynamic lighting, complex materials, or physics, the server handles it. Your device doesn’t do any of that heavy lifting.

3️⃣ The Frame Gets Compressed + Encoded

Once the server has the frame ready, it compresses it using video encoding tech (usually H.264, H.265, or newer codecs like AV1). The goal is to shrink the size of the data without making it look ugly — so it can stream smoothly even on regular internet connections.

👉 Here’s a pro tip: H.265 offers better compression than H.264 at the same quality, but takes more processing power to encode/decode. AV1’s even better, but not all browsers support it yet.

4️⃣ The Frame Streams to Your Device

Now that the frame’s compressed, it’s streamed to your device using a protocol like WebRTC, chosen because it’s designed for low-latency, real-time applications (think video calls, live gaming).

Your device’s job? Just decode that stream and display the pixels on your screen. Even low-end devices can usually handle this without breaking a sweat.

5️⃣ The Cycle Repeats in Milliseconds

This process loops continuously: input → render → compress → stream → decode → display. Done right, it feels seamless, like the app is running locally.

That’s the magic of Pixel Streaming: your users get to experience high-fidelity graphics and real-time interaction without worrying about their device specs. The cloud does the hard work; they just see the result. But beyond the technical flow, the real question is: why does this matter? Let’s look at where Pixel Streaming shines, why it’s becoming the go-to choice for demanding 3D applications, and how it stacks up against cloud gaming, app streaming, remote desktop, and traditional on-device rendering.

What Are Advantages Of Pixel Streaming?

I’ve seen teams create stunning Unreal Engine scenes or Unity builds, only to hit a wall when it’s time to share. The client opens it on a basic laptop or tablet, and suddenly the frame rate tanks. That’s where Pixel Streaming completely changes the game.

It lets you run your app on powerful cloud GPUs and stream the output as pixels, like a video feed. The user doesn’t need high-end hardware. Just a browser. I’ve watched people explore complex 3D models or test VR demos on tablets without any local install or setup.

That’s another huge win: no installs, no downloads, no “can you run this on your machine?” headaches. You send a link, they click, it works. This simplicity opens doors for demos, client reviews, training, or public showcases where you don’t control what device people have.

Updates are effortless too. Patch the app once on the server and everyone gets the latest version the next time they open it. No chasing people to update. No fighting with different OS versions or hardware setups.

And security? It’s solid. The app code, models, and data never leave the server. The user only sees the pixels. It’s a safer way to share sensitive projects, pre-release builds, or proprietary tools.

Scaling is another advantage. Need to demo to one person? Easy. Need to stream to hundreds at a virtual event? Spin up more cloud instances—no extra hardware needed on your end.

If you ask me, Pixel Streaming removes the friction. You focus on building great experiences. And your audience gets to enjoy them, no matter what device they’re using.

How to Implement Pixel Streaming?

If you’re considering Pixel Streaming for your project, you’ve probably already weighed the trade-offs between building your own setup and using a managed service. Let’s break it down, what’s actually involved when you go the traditional route, and where alternatives like Vagon Streams can save you time (and headaches).

#1: The Traditional & Technical Self-Hosted Way To Implement

In its raw form, Pixel Streaming means you’re hosting the whole environment yourself. You set up cloud GPU servers, usually on platforms like AWS or Azure, and configure everything: the rendering machine, network layer, encoding pipeline, security, client app, and so on.

On AWS, for example, you’d spin up a GPU-accelerated EC2 instance, install your engine build, set up WebRTC signaling servers, and fine-tune bandwidth and latency settings. It works — but it takes time, skill, and ongoing management. You can check out our detailed guide for implementing pixel streaming on AWS.

Azure’s process is similar: deploying high-performance VMs, configuring ports, managing firewalls, and handling GPU drivers. You can follow our comprehensive tutorial for implementing pixel streaming on Azure.

Both methods give you control. But they also mean you’re responsible for uptime, scaling, security patches, and cost management.

Unreal Engine vs Unity — What’s Different?

At the core, Pixel Streaming works similarly for both: a server renders frames based on user input and streams them as video. But Unreal Engine has native Pixel Streaming support out of the box — it’s built into the engine. You package your project with Pixel Streaming enabled, deploy it to your server, and the engine handles WebRTC signaling and stream generation.

Unity doesn’t have native Pixel Streaming in quite the same way. Instead, you’d use Unity Render Streaming, which relies on WebRTC to deliver frames. The setup requires extra components, like signaling servers, and usually more customization. Unity’s approach is powerful, but tends to be more hands-on than Unreal’s built-in system.

#2: The Simpler & Powerful Alternative — Vagon Streams

Here’s where Vagon Streams makes life easier. Instead of building and managing infrastructure yourself, you can upload your app, Unreal or Unity, and start streaming in minutes. There’s no server configuration, no manual scaling, no WebRTC tinkering.

Vagon Streams is built with native support for Pixel Streaming, Render Streaming, and its own streaming technology, optimized for low latency, high resolution, and smooth interaction across devices. Whether you’re showcasing an architectural walkthrough, hosting a virtual event, or running a multiplayer demo, Vagon Streams lets you focus on the experience, not the setup.

In short: you can absolutely roll your own Pixel Streaming setup on AWS, Azure or eve from your local device. But if you’d rather skip straight to streaming without the infrastructure complexities, Vagon Streams is ready when you are.
