OBS Studio is a sensible first streaming app to test on a low-end PC, but no software is universally the lightest. The game, encoder, output settings, scene complexity, and your specific CPU and GPU all affect performance. Start with a conservative setup, test it in the game you actually play, and compare the results before changing hardware.
Which streaming software should you try first?
Start with OBS Studio if you are comfortable adjusting settings. Its Auto-Configuration Wizard can suggest settings for your system, and it supports software and hardware encoding where the necessary hardware and drivers are available. OBS itself cautions that basic system compatibility does not guarantee smooth streaming or recording: workload changes with the encoder, resolution, frame rate, and scene complexity. OBS system requirements
That makes OBS a practical first choice, not a proven speed winner. The official sources reviewed do not provide equivalent-PC benchmarks comparing these applications, so there is no evidence-based universal ranking by resource use. Test the apps you are considering on your own machine and game.

What determines whether a low-end PC can stream smoothly?
Encoder: CPU work or GPU work
x264 is a software encoder that uses the CPU. Hardware encoders such as NVENC can shift encoding work to a specialized component in a supported GPU, which may reduce CPU load. OBS generally recommends hardware encoding for performance, but the available encoder depends on your actual GPU and drivers; not every older GPU has a useful option. A hardware encoder is not a guarantee of better quality or smoother gameplay on every setup. OBS hardware encoding guidance
Resolution and frame rate
Higher output resolution and frame rate increase the work involved in encoding. If the PC struggles, begin with a modest target such as 720p at 30 fps, which Streamlabs recommends as a performance-oriented starting point, then test whether your game and system can sustain it. Treat it as a starting point, not a universal optimum. Streamlabs setup guide

Game, scenes, and other programs
The game itself may already be using most of the available CPU or GPU. Animated overlays, browser sources, complex scenes, plugins, and other open programs add work. A simple scene and a test in the actual game give you a more useful reading than checking the streaming app while idle.
Network upload
A stream can have encoding headroom but still fail if the connection cannot sustain the configured output. XSplit recommends at least 5 Mbps upload for HD quality, but that figure is XSplit’s guidance rather than a universal requirement. Check the target platform’s current guidance for the resolution and frame rate you choose, and test the connection under realistic conditions.

How to set up and test a conservative stream
- Check compatibility: Confirm the app supports your operating system and review its current minimum specifications. Open its encoder settings and note which hardware encoder options actually appear; do not assume your GPU supports one.
- Configure a baseline: In OBS, open Tools > Auto-Configuration Wizard and follow its prompts. Alternatively, begin at 720p and 30 fps as a conservative test setting. Apply the chosen settings in the app’s video and output controls; names and layout can vary by version.
- Compare encoders if available: If a compatible hardware encoder appears, run a short test with it and another with x264. Keep resolution, frame rate, game, and scene the same so you can judge the difference. If no hardware encoder appears, use an available software option and lower the workload as needed.
- Simplify the scene: Temporarily remove animated overlays and unnecessary browser sources, and close programs you do not need. Add elements back one at a time after the basic stream is stable.
- Test under real conditions: Play the game while streaming privately or using the platform’s available test method. Watch for dropped or skipped frames, encoder overload warnings, stutter in the game, and audio or video sync issues. Make one change at a time and repeat the test.
- Keep the setting your PC can sustain: If the stream or game falters, lower output resolution or frame rate, simplify the scene, or try the other available encoder. A stable, watchable output is more useful than a higher setting the computer cannot maintain.
Troubleshooting common performance problems
| Symptom | Likely area to check | First adjustment |
|---|---|---|
| The game stutters while the stream is running | The game and encoder may be competing for CPU or GPU resources. | Try a hardware encoder if supported, reduce output resolution or frame rate, simplify the scene, and close unnecessary programs. |
| The stream reports encoder overload or skipped frames | The selected encoder settings or scene may be too demanding for the system. | Use a lower output target, compare an available hardware encoder with x264, and remove animated overlays or extra browser sources for a test. |
| The stream disconnects or drops network frames | Upload capacity or connection stability may be limiting the stream rather than the app’s rendering performance. | Check upload performance during a test and compare your settings with the streaming platform’s current recommendations. |
| No hardware encoder appears in settings | The GPU, driver, or installed software may not expose a supported encoder. | Check your GPU and driver support; do not assume all older graphics hardware includes a usable encoder. Test x264 at lower settings if needed. |
| Performance worsens after adding overlays or sources | Scene complexity can add encoding and rendering workload. | Remove the newest source or effect, retest, and restore elements individually to identify the expensive component. |
When should you upgrade hardware?
First identify the bottleneck. If the game is already stuttering before streaming, the game itself may be too demanding. If the game is smooth until encoding starts, test encoder choices and lower the output workload. If the picture and game are fine but the stream disconnects, investigate the network. The requirements and setup guidance above do not justify a particular GPU purchase for an unspecified PC, and a capture card is not a default fix for single-PC performance.
XSplit’s capture-card instructions describe a different arrangement: a gaming PC sends video to a separate streaming PC. That can move streaming work to another computer, but it is a two-PC workflow, not proof that adding a capture card solves resource limits on one low-end PC. XSplit dual-PC capture-card guide
