Game Streaming Setup Guide: Equipment, Software and Platform Basics

What you need before the first stream

At the most basic level, a game stream needs three things: a computer able to run both the game and broadcasting software at the same time, a free encoder program, and enough upload bandwidth to send video to a platform like Twitch or YouTube. OBS Studio, the most widely used free broadcasting program, lists its own minimum technical requirements rather than a fixed price tag for hardware.

On Windows, OBS Studio requires a DirectX 10.1-compatible graphics card and Windows 10 or 11. On macOS it needs an Intel or Apple Silicon processor, an OpenGL 3.3-compatible GPU, and macOS 11 (Big Sur) or later. On Linux it needs an OpenGL 3.3-compatible GPU and a working X window system or Wayland session, according to OBS Project's official system requirements page. The same page notes that processor needs vary a lot depending on the encoder, resolution, frame rate and how complex the on-screen scene is, so there is no single CPU figure that fits every setup.

Step-by-step: setting up OBS Studio

1. Check your computer against OBS Studio's official GPU and OS requirements for Windows, macOS or Linux before installing anything.
2. Download OBS Studio and run the built-in Auto-Configuration Wizard, which OBS Project describes as adjusting settings based on whether you are streaming fast-paced gameplay or recording, and on your hardware and network conditions.
3. Build a Scene and add Sources: OBS Project's quick-start guide lists Display or Window Capture for the desktop, a Windows-only Game Capture option tuned for 3D games, and Video Capture Source for webcams or capture cards.
4. Confirm audio is working. By default OBS Studio captures desktop audio and microphone input, and levels can be checked in the Audio Mixer volume meters at the bottom of the main window.
5. Choose a microphone. Reviewers at Eneba's gaming-gear guide point to the FIFINE AM8W as a budget pick for beginners, highlighting that it works over both USB and XLR and uses a cardioid pickup pattern described as isolating the speaker's voice from background noise.
6. Pick a streaming platform and check its account rules (see below) before going live for the first time.
7. Match your bitrate and upload speed to the resolution you want to stream at, using the platform's published figures rather than guessing.

Platform basics: bitrate and bandwidth

Twitch and YouTube publish different recommended bitrates for the same resolutions, and streamers need enough spare upload bandwidth above the bitrate itself. A 2026 Twitch-focused streaming guide published by Streamscharts lists minimum upload speeds of 5 Mbps for 720p at 30 frames per second, 7 Mbps for 720p at 60 fps, 8 Mbps for 1080p at 30 fps, and 10 Mbps for 1080p at 60 fps, with a suggested bitrate range of roughly 2,500–6,000 kbps overall across those settings. YouTube's own Help Center gives separate, generally higher bitrate ranges for its live encoder ingestion using the H.264 codec.

YouTube's Help Center also recommends a 2-second keyframe interval, not exceeding 4 seconds, and audio encoded as AAC or MP3 at 128 kbps for stereo sound or 384 kbps for 5.1 surround.

Account basics before going live

YouTube's official live-streaming guide lists three prerequisites: the channel must be verified, it must have had no live-streaming restriction in the past 90 days, and the creator must be at least 16 years old. YouTube's guide also describes several ways to go live, including a simple webcam stream straight from a computer, mobile streaming, and console streaming, alongside an encoder-based stream — the method gaming broadcasts normally use — which supports overlays, external microphones and multiple cameras.

That same Streamscharts guide recommends turning on two-factor authentication before streaming seriously, framing it as protection once a channel starts gaining followers or payout eligibility, rather than a requirement needed only once a channel is already established.

Choosing basic equipment

Beyond the computer itself, a microphone is the first piece of dedicated equipment most new streamers add. Eneba's gaming-gear buying guide recommends the FIFINE AM8W for streamers starting on a budget, citing its dual USB/XLR connectivity — useful if a streamer later upgrades to an audio mixer — and straightforward controls. The same guide notes it does not cover webcams or capture cards in detail, so streamers who want on-camera video or console capture should check a device's own specifications against OBS Studio's Video Capture Source requirements before buying.

Putting it together

A workable first setup, based on the sources above, is: a computer meeting OBS Studio's GPU and OS minimums, OBS Studio itself configured through its Auto-Configuration Wizard, a Game Capture or Display Capture source for the game, an Audio Input Capture source for a USB microphone, a verified account on the chosen platform with two-factor authentication enabled, and an upload speed that comfortably clears the bitrate needed for the target resolution.
