Whether a game streams smoothly depends on your CPU and GPU, the encoder you can use, output settings, the game itself, and how complex your scenes are. Start with a conservative setup, test it with the game you actually play, and find the bottleneck before buying hardware.
Which streaming software should you try first?
Start with OBS Studio if you want a flexible application and are willing to configure and test it. OBS says that meeting its compatibility requirements does not guarantee that a computer can stream or record smoothly; processor demands vary with the encoder, resolution, frame rate, and scene complexity. Its Auto-Configuration Wizard can help select settings for your system. OBS system requirements
That makes OBS a practical first trial, not a proven speed champion. The official information available for these apps does not provide equivalent-machine benchmarks, so it cannot establish which one uses the fewest resources on every low-end PC.
How the options compare
Published minimum specifications describe vendor-stated compatibility, not how well an app will run a demanding game and stream at the same time. Check each vendor’s current requirements before installing, since operating-system support and specifications can change.

| Software | What the official information says | What that means for a low-end PC |
|---|---|---|
| OBS Studio | OBS says compatibility does not guarantee streaming or recording capability. CPU demand depends on encoder, output resolution and frame rate, and scene complexity. Its wizard helps configure settings. Source | A flexible first app to test; the published information does not prove it is faster than alternatives on the same hardware. |
| Streamlabs Desktop | Its requirements list Windows 11 or macOS 12 and later, plus 8 GB RAM as minimums. Its setup guide recommends 720p at 30 fps for performance and describes software and hardware encoding. Requirements · Setup guide | Consider it if you value an integrated setup and overlays. The minimums do not establish how it will handle a demanding game on your PC. |
| XSplit Broadcaster | XSplit lists Windows 10 64-bit, a second-generation Core i5 or equivalent, 8 GB RAM, and a GeForce- or Radeon-class GPU with DirectX 10.1 support as minimums. It recommends at least 5 Mbps upload for HD quality. Requirements | Consider it if its production features suit you, but the listed requirements do not show that it uses fewer resources. The upload recommendation is XSplit’s, not a universal rule. |
| PRISM Live Studio | Its FAQ lists Windows 10/11 64-bit, 8 GB RAM, a GTX 1060 or equivalent, and an Intel Core i3-9100 or i5-7600 or above as Windows minimums. Its desktop page advertises low CPU usage, a vendor claim rather than an independently benchmarked result. FAQ · Desktop page | It may suit you if its interface or platform integrations matter. Its stated GPU minimum means it should not automatically be assumed to suit an older integrated-graphics PC. |
Choose an encoder that fits your hardware
The encoder determines where much of the video-encoding work happens. OBS’s x264 option encodes in software using the CPU. A supported hardware encoder, such as NVENC on a compatible GPU, shifts encoding work to a dedicated component in the graphics processor. OBS generally recommends hardware encoding for performance, but availability and results depend on the GPU generation, drivers, and specific setup. An older PC may not have a useful supported hardware encoder. OBS hardware encoding
- Check which encoder options actually appear in your streaming app; do not assume that a GPU brand or age guarantees a particular option.
- If a supported hardware encoder is available, compare it with x264 in a short test. Moving work off the CPU may help, but it does not guarantee smooth gameplay or better results in every configuration.
- Use the same game, scene, and output settings for each test so you can tell whether the encoder change made a difference.
Set up a conservative test stream
- Check compatibility: Confirm your operating system and hardware against the application’s current requirements. In the app, note the encoders that are available on this computer.
- Start with a modest output: Run the OBS Auto-Configuration Wizard, or begin with a conservative preset. Streamlabs recommends 720p at 30 fps as a performance-oriented starting point; treat it as a setting to test, not a guarantee or universal optimum. Streamlabs setup guide · OBS setup guidance
- Simplify the scene: Temporarily remove animated overlays and extra browser sources, and close programs you do not need. OBS identifies scene complexity as a factor in CPU demand, while Streamlabs cautions that other running programs and overlays affect workload.
- Test the real workload: Run the game you intend to stream and make a short test using your intended scene. A desktop-only preview will not show how the game and stream behave together.
- Change one setting at a time: If the test struggles, compare an available hardware encoder with x264, then adjust output settings or scene elements in separate tests. This makes it easier to identify what helped.
Diagnose the bottleneck before spending money
A stuttering stream can come from the game competing for CPU or GPU resources, the encoding workload, or the network. The published app requirements do not identify the limiting component in an individual PC. Change one variable at a time and retest the same game and scene. If simplifying overlays or changing encoders helps, you have evidence about the workload; if not, avoid assuming that a particular GPU, capture card, or application purchase is the answer.

If gameplay or the stream stutters
- Try a less demanding output setting and retest the game; performance depends on resolution and frame rate as well as encoder choice.
- Reduce animated overlays and unnecessary browser sources, and close other running programs.
- Compare x264 with a compatible hardware encoder if one is available. If the hardware encoder does not appear, check the app, drivers, and actual hardware support rather than assuming it exists.
If you are considering a capture card
A capture card is not a general fix for one PC that is struggling to game and stream. XSplit’s capture-card instructions describe a dual-PC arrangement: a gaming PC sends video to a separate streaming PC. That is a different workflow and requires a second computer. XSplit dual-PC guide
