In the world of online gaming and streaming, performance is everything. Whether you're streaming to an audience of a few friends or thousands of fans, ensuring smooth gameplay and high-quality streams is essential. Streamers often find themselves at a crossroads when deciding between a single PC or a dual PC setup. This guide will delve into the advantages and disadvantages of each option, assist you in determining if a dual PC setup is truly necessary, and provide a step-by-step overview of the necessary hardware and software. While a modern gaming PC can typically handle broadcasting your gameplay online, incorporating a second computer can enhance the streaming experience. It is even possible to utilize older hardware for this purpose, provided it meets the minimum requirements of your chosen streaming platform.
1. Pros and Cons of a Dual PC Setup
Pros:
Uninterrupted Performance: By splitting the workload between two PCs, one dedicated to gaming and the other to streaming, you eliminate the risk of lag, stuttering, or frame drops caused by the intense demands of both tasks running on the same machine.
Higher Quality Streams: With a dedicated streaming PC, you can use higher quality settings in your streaming software, providing your audience with clearer and smoother visuals without compromising your in-game performance.
Reduced Stress on Hardware: Running both tasks on separate machines means less strain on your components, which can lead to longer hardware lifespan and fewer overheating issues.
Cons:
Cost: Setting up and maintaining two PCs is more expensive. You'll need double the components, including motherboards, CPUs, GPUs, and storage.
Complexity: A dual PC setup requires more knowledge and effort to set up and manage. You'll need to understand how to configure the connection between the two machines, and ensure that your audio and video signals are properly synced.
Space and Power: Two PCs take up more physical space and power, which might be a consideration if your workspace is limited.
2. Do You Need a Dual PC Setup for Gaming/Streaming?
A dual PC setup isn't necessary for everyone. Here's a breakdown of who might benefit from one and who might not:
Who should consider a Dual PC Setup:
Professional Streamers: If you're streaming to a large audience and demand the highest quality in both your gameplay and your stream, a dual PC setup might be worth the investment.
Content Creators: Those who produce a lot of content and need to ensure smooth editing and rendering while gaming could benefit from a dual PC setup.
Competitive Gamers: For those in competitive gaming, where every millisecond counts, having a dedicated gaming PC ensures that performance is never compromised.
Who Doesn't Need a Dual PC Setup:
Casual Gamers: If you stream occasionally and primarily game for fun, a well-equipped single PC will likely meet your needs.
Budget-Conscious Streamers: If you're on a tight budget, it's better to invest in a single, powerful PC rather than splitting your funds between two less powerful machines.
3. Hardware and Software Requirements for a Dual PC Setup
To set up a dual PC streaming rig, you'll need the following:
Hardware:
Two PCs: One for gaming, one for streaming. Ideally, the gaming PC should have a powerful CPU, a high-end GPU (e.g., NVIDIA RTX 30/40 series), and plenty of RAM (at least 16GB, though 32GB is Preferred). The streaming PC can have a less powerful CPU, but still requires a decent GPU for encoding any NVENC equipped modern Nvidia GPU or AMD 7000 series with the AV1 Encoder.
Capture Card: A capture card is essential for transferring the video signal from your gaming PC to your streaming PC. Popular options include the Elgato HD60 Pro and AVerMedia Live Gamer 4K.
Microphone/Audio Mixer or Interface: A standalone microphone plugged into the streaming PC, ensures your audience hears you clearly. For simultaneous in-game chat, a mixer with at least two channels is required—one channel connects to the gaming PC, and the other to the streaming PC, allowing the microphone to be used by both.
Webcam or Camera: Adding a webcam to your setup can personalize your stream. Connect the webcam to your streaming PC and ensure that the audio is muted in the streaming software to prevent interference with your microphone. If you use a green screen, you can overlay your image on top of the gameplay, although this adds complexity. Starting with a simple background is perfectly fine, and you can upgrade your setup over time.
Cables: You'll need HDMI cables to connect your gaming PC to the capture card in your streaming PC, as well as other necessary cables for audio and peripherals.
Peripherals: You will need a mouse and Keyboard for both systems
Software:
Streaming Software: OBS Studio is the most popular free option, offering extensive customization and support for dual PC setups. Other options include Streamlabs OBS and XSplit.
Voice Chat Software: Programs like Discord or TeamSpeak can be set up to run on either PC, but you'll need to configure your audio routing carefully.
Screen Mirroring Software: If you want to monitor your gaming PC from your streaming PC, software like Parsec or Remote Desktop can help.
4. Single PC Setup: What You Need to Know
If you're sticking with a single PC for both gaming and streaming, here’s what you should consider:
Performance Impact:
Streaming from a single PC can put significant strain on your CPU and GPU, especially if you're playing demanding games. This can lead to reduced frame rates, increased input lag, and lower overall performance.
Expect to drop some in-game settings or reduce your stream quality to maintain a smooth experience for both yourself and your viewers.
Hardware Upgrades:
CPU: Invest in a high-performance CPU with multiple cores and threads. The Intel Core i7/i9 series or AMD Ryzen 7/9 series are great choices for gaming and streaming simultaneously.
GPU: The most powerful GPU you can afford will help you to get the most out of your system. Nvidia's NVENC encoder is on all of their modern GPU's, and AMD 7000 series GPU's now have a built in AV1 Encoder
RAM: 32GB should be the minimum to consider for a dual use system, 32GB will provide a vastly improved stream and gaming experience over 16GB.
Cooling Solutions: Streaming and gaming simultaneously can cause your PC to heat up quickly. Consider upgrading your cooling system with high-performance air or liquid cooling.
Do I need a Capture Card? You do not for a single PC setup
Setting up your dual gaming/streaming PC Setup
Before going live, you’ll need to install streaming software on your PCs. OBS, SLOBS, and XSplit are all viable options. Once installed, ensure your capture card is connected or installed in the streaming PC, and proceed to connect the two computers.
Connecting the Two PCs: Connecting your PCs is straightforward but must be done correctly.
For an external capture card like the Elgato HD60 S, connect an HDMI cable from your gaming PC to the “in” port of the capture card. Then, connect the capture card to your streaming PC via USB.
For an internal capture card, install it in the streaming PC according to the manufacturer’s instructions. Then, connect your gaming PC’s graphics card to the HDMI “in” port on the capture card installed in the streaming machine.
After the hardware is connected, adjust your display settings on the gaming PC to ensure the HDMI output is duplicated on your primary gaming monitor. This ensures the capture card doesn’t limit your gaming monitor’s capabilities. On the streaming PC, add the capture card as a video source in your broadcasting software, and ensure the video and audio are properly synced.
