The short answer is nuanced: officially, Steam Link was never designed nor advertised to support a native 120fps streaming experience. The original Steam Link hardware is limited by its 100Mbit network card. While you might achieve results that feel smoother than 60fps in some scenarios, a consistent, true 120fps experience is not something you can reliably expect. However, modern solutions that leverage Steam Remote Play (the software behind Steam Link) on different hardware, coupled with tweaks and workarounds, can potentially push closer to that goal.

Let’s break down why, explore the limitations, and examine alternative solutions that might better suit your high-refresh-rate gaming needs.

Understanding the Steam Link Ecosystem

Before diving into frame rates, it’s crucial to understand what Steam Link was and what Steam Remote Play is.

Steam Link (Hardware): This was a dedicated streaming device discontinued by Valve. It allowed users to stream games from their gaming PC to a TV or monitor.
Steam Remote Play (Software): The technology that powered Steam Link lives on as software. It’s integrated directly into the Steam client and allows you to stream games to various devices, including PCs, Macs, Linux machines, Android devices, iOS devices, and even other Steam Decks.

The original Steam Link hardware’s limitations significantly impact the 120fps discussion. Since it is limited by the 100Mbit network card, any network speeds higher than this would be irrelevant. The move to Steam Remote Play provides the opportunity for more robust network card functionality, allowing higher FPS streaming capabilities.

Bottlenecks and Limitations

Even with a powerful gaming PC and a fast network, several bottlenecks can prevent you from achieving a stable 120fps streaming experience with the Steam Link ecosystem:

Network Bandwidth: Streaming high-resolution, high-frame-rate video requires significant bandwidth. While Steam Remote Play can dynamically adjust bitrate, exceeding your network’s capacity will result in lag, stutters, and a poor overall experience. The original Steam Link device’s 100Mbit Ethernet port inherently limits the possible bandwidth available.
Encoding and Decoding: Your gaming PC must encode the game video in real-time, and the receiving device (the Steam Link device or a device running Steam Remote Play) must decode it. This process consumes CPU/GPU resources on both ends. Inadequate hardware on either end will lead to performance issues. Older devices or low end processors may cause serious lag and a low frame rate in general.
Latency: Every step in the streaming process adds latency, from capturing the game frame to encoding, transmitting, decoding, and displaying it on the remote device. High latency makes fast-paced games unplayable. The Steam Link hardware itself contributed to some baseline latency.
Hardware Limitations: As mentioned, the original Steam Link hardware is limited by its older hardware, including its network card. The best performance would be through alternative hardware, such as Steam Deck.

Pushing the Limits: Configuration and Tweaks

While a true, stable 120fps experience with the original Steam Link is unlikely, you can try these tweaks to maximize your streaming performance and potentially achieve smoother results:

Wired Connection: Always prioritize a wired Ethernet connection for both your gaming PC and the Steam Link device. This minimizes latency and provides a more stable connection than Wi-Fi.
5 GHz Wi-Fi (If Wired Isn’t Possible): If you must use Wi-Fi, use the 5 GHz band instead of the crowded 2.4 GHz band.
Router Quality: Use a high-quality router that supports 802.11ac or 802.11ax (Wi-Fi 6) standards.
Adjust Streaming Settings: In the Steam client on your gaming PC, go to Settings > Remote Play > Advanced Host Options. Experiment with settings like:
- Hardware Encoding: Enable hardware encoding (if supported by your GPU).
- Prioritize Network Traffic: Prioritize network traffic for streaming.
- Limit Bandwidth: Start with a lower bandwidth limit (e.g., 30 Mbps) and gradually increase it until you find the sweet spot between image quality and performance.
- Disable Hardware Decoding: Try disabling hardware decoding on the client device if you suspect issues on that end.
Game Settings: Reduce in-game graphics settings to increase the game’s frame rate on your gaming PC. This will make it easier for the PC to encode the video stream smoothly.

Alternative Solutions: Moonlight and Beyond

If 120fps streaming is a must-have, consider alternatives to the Steam Link hardware. Moonlight is an open-source implementation of Nvidia’s GameStream protocol. It often offers lower latency and better image quality compared to Steam Remote Play, particularly when streaming from an Nvidia GPU. Moonlight and Sunshine offers streaming up to 120 FPS.

Other alternatives include Parsec and GeForce Now (cloud gaming). Each platform has its strengths and weaknesses, so experiment to find the best fit for your setup and needs.

The Future of Streaming: Steam Deck and Remote Play Enhancements

Valve continues to improve Steam Remote Play. The Steam Deck can achieve impressive streaming results, particularly when used with a fast network and optimized settings. Future updates to Steam Remote Play may further enhance performance and potentially bring more reliable 120fps streaming to a wider range of devices. The Games Learning Society has a great interest in this, as low latency and high FPS can greatly enhance the quality of games used for learning.

Frequently Asked Questions (FAQs) about Steam Link and 120fps
