How to Stream PC Games to Twitch

2020-08-20

Game streaming to Twitch on a PC is much simpler than with a console, because, if you have the right hardware, you can play the game, broadcast and run your chat from the same computer. Below, we’ll explain what you need and how to get started streaming PC games to Twitch. 

What You Need to Stream PC Games to Twitch 

  • A capable PC: Though the recommended specs will vary, based on the game and settings you wish to play at. We recommend that you use a system with at least a 6-core CPU (e.g. Ryzen 5 1600 or Core i5-8400 or better), 16GB RAM, and a graphics card from the past two generations (RX 570 or GTX 1060 or better). While playing League of Legends doesn’t require a lot of high-end specs on a PC, streaming needs more horsepower. Using GPU assisted encoding can help a lot, and Nvidia's most recent Turing architecture GPUs (GTX 1650 Super or above) can beat CPU encoding quality with very little performance hit.
  • Your PC should also exceed the minimum specs for any game you want to play and stream. Check Can You Run It or Google to find the minimum and recommended system requirements, and ideally, you want to meet the recommended specs.
  • Multiple monitors: It’s hard to play a game and view chat on one monitor. For the most comfortable and efficient stream, two monitors at a minimum are necessary. Use one for your full-screen game, the second for your chat, and alerts. If you have a third display, that can monitor your recording software.
  • Headset: The best gaming headsets offer great quality audio for gaming and also have some noise-canceling abilities for chat.
  • Microphone (optional): Though any old headset mic will do, one of the best gaming microphones will give you better audio quality.
  • Webcam: In order for your audience to see your reactions, you’ll need a camera, preferably one of the best webcams. However, many of the top models have been in high demand during this pandemic.

You’ll now see your overlay. Whether you’re building an overlay yourself or importing it from StreamElements, adding the process is the same, right-clicking Scenes, and adding an image, video, gifs, or text. If you’d like to solely add your stream alerts because you’re building your overlay on your own, add the alerts’ URL to Browser. It will go invisible because it activates when someone follows, subscribes, or hosts you.

A great addition to a webcam is . It’s essential to have lighting to highlight your features. Standing lightboxes, a ring light, or any type of lighting increases your production value. It helps your camera to function at it’s highest capability. 

10. Add your microphone if you have one. A stand-alone microphone is a good investment for a streaming career. It allows a better sound quality output and a polished look. Having a mic leaves your headset free for party chats on your console. Adding a microphone to OBS is easy because it recognizes the mic and will create a channel for it under Audio Mixer. It does the same thing when it recognizes the Desktop audio is available.

If you’d like to change your game, for example from Rogue Company to CounterStrike: Global Offense, there’s no need to create another source. It’s easier to right-click Game Capture - Preferences then select the full-screen application you would like to display. 

12. Start your Livestream on Twitch. Your Twitch account is connected to OBS. To start your live stream click the Start Stream button in the lower right-hand corner. You can edit your stream title and game on your Twitch Stream Manager. 

These are all the tools it takes to stream on PC. The place where you’ll spend the most time is getting your overlay to look how you want. Many streamers tweak their overlays often to match the games or seasons. With software like OBS and StreamElements, you can add as many overlays as you’d like without having to delete any. And you can take your overlays anywhere by saving them so, if you’re streaming from a new PC, you don’t have to rebuild your overlay or re-add your alerts.
