A weak PC can still capture decent footage if you treat OBS recording settings for a low-end PC as a budget: 720p, 30 fps, a hardware encoder and a modest bitrate. Anything beyond that spends power your game needs. Do these four things before touching other options and most stutter disappears.

Quick Answer

Set Base and Output Resolution to 1280 by 720, frame rate to 30, the encoder to your GPU's hardware option (or QuickSync on Intel graphics), and the bitrate to about 8 000 to 12 000 kbps. Record to MKV on an SSD. Lower the game's own graphics settings, as that frees more power than any OBS tweak.

📉 Resolution and Frame Rate

In OBS open Settings, then Video. Keep Base Resolution at your screen size, set Output (Scaled) Resolution to 1280 by 720 and choose a common FPS value of 30. The scaling filter matters too: Bilinear is the lightest, Bicubic costs a little more and looks cleaner.

Dropping from 1080p to 720p reduces the pixels OBS must handle by more than half, and 30 fps halves the frames. Together that is the biggest relief a struggling machine can get.

⚙️ Encoder and Bitrate

Go to Settings, then Output, and choose Advanced mode. On the Recording tab pick a hardware encoder if you have one. A software encoder on an older dual-core chip will drop frames, since it competes with the game.

  • Rate control: CBR is simplest on a basic setup.
  • Bitrate: 8 000 to 12 000 kbps gives a decent 720p picture.
  • Keyframe interval: 2 seconds.

Higher figures look little better here and fill the drive far quicker.

💾 Free Up Everything Else

Record to an SSD where possible. A slow, nearly full hard drive stalls the write and shows up as skipped frames. Close browsers, launchers and overlays, disable Game Bar capture, and on a laptop plug in the charger and pick the high-performance power plan.

If you also want voice-over, a plain USB mic from the streaming essentials range adds little load compared with a webcam.

🧰 Small Upgrades That Pay Off

Before replacing the whole machine, look at cheap fixes. Extra RAM, from 8 GB to 16 GB, stops background swapping, while a solid-state drive removes the disk bottleneck. A capture of just your desktop or a lighter game also needs far less power than a modern shooter.

Face-cam is optional on a tight system. If you want one, a basic webcam at 720p is plenty and keeps CPU use down.

Frequently Asked Questions

What resolution should a weak PC record at?

Aim for 720p at 30 fps. Scaling the output and lowering the game's own settings frees more power than any filter change.

Which encoder is lightest on an older machine?

The hardware encoder in your graphics card, or QuickSync on Intel integrated graphics. Both move the work off the processor.

What bitrate works for local recording?

Roughly 8 000 to 12 000 kbps for 720p. Beyond that the picture barely improves on a basic setup but files balloon.

Does the recording drive matter?

Very much. A slow, almost-full disk stalls the recording, whereas an SSD with free space keeps frames flowing.

How do I free up resources while recording?

Close extra tabs, launchers and overlays, turn off Game Bar capture, and use the high-performance power plan on a laptop.

Is it worth upgrading just to record?

Often a small upgrade such as more RAM or an SSD helps more than a new PC. Compare it against what you actually need before you pay.
