Best OBS Recording Settings for a Low-End PC (No Lag)

If recording turns your smooth game into a slideshow, your OBS settings are asking too much of your hardware. The fix is to spend resources where they matter and cut the rest. Here is how to record watchable gameplay on a modest PC without the stutter.

The single biggest win: use a hardware encoder

The encoder choice matters more than anything else on a low-end machine.

• x264 runs on your CPU and competes directly with your game. On a weaker processor it causes stutters and dropped frames.
• A hardware encoder (NVENC for NVIDIA, AMF for AMD, QuickSync for Intel) runs on dedicated silicon and barely touches your game's performance.

If your GPU has a hardware encoder, use it. This one change fixes most lag problems by itself.

Low-end vs balanced settings

Setting	Low-end (smoothness first)	Balanced
Encoder	Hardware (NVENC/AMF/QSV)	Hardware (NVENC/AMF/QSV)
Base resolution	1920x1080	1920x1080
Output resolution	1280x720	1600x900 or 1080p
Downscale filter	Bilinear (cheapest)	Bicubic
FPS	30	30-60
Rate control	CBR	CQP
Bitrate / quality	8,000-12,000 Kbps	20,000+ Kbps or CQP 23
Format	MKV (remux to MP4)	MKV (remux to MP4)

Lower your output resolution

Recording at 720p instead of 1080p slashes the work for both the encoder and your disk. Set your base canvas to your monitor's resolution, then set the output (scaled) resolution lower, for example 1280x720. The footage is still perfectly clean for sharing clips.

Pick the right downscale filter

When OBS scales down, the downscale filter controls quality versus cost. On a low-end PC choose Bilinear, the cheapest option. If you have headroom, Bicubic looks a bit sharper. Save Lanczos for stronger systems, it's the most expensive.

Drop to 30 FPS

60 FPS doubles the frames your hardware has to encode. For many games, especially slower ones, 30 FPS recordings look fine and roughly halve the load. Reserve 60 FPS for fast shooters only if your system can handle it.

Keep the bitrate reasonable

A sky-high bitrate strains your disk and produces bloated files for no visible benefit at lower resolutions. With CBR at 720p30, 8,000-12,000 Kbps is plenty. If you use CQP, a value around 23-26 keeps files small while staying clean.

What to sacrifice, in order

When you still need more performance, give things up in this order:

1. FPS (60 to 30) - usually the easiest win.
2. Resolution (1080p to 720p) - big load reduction.
3. Bitrate (lower it) - smaller files, faster disk writes.
4. Encoder preset - use the fastest/lowest-latency preset your encoder offers.

Protect your in-game frame rate above all. A choppy recording of smooth gameplay is better than a smooth recording of a stuttering game.

A few extra tweaks

• Close background apps (browsers, chat overlays) to free RAM and CPU.
• Record to an SSD if you can; slow drives cause dropped frames.
• Use Game Capture rather than Display Capture, it's more efficient.

Even a budget PC can produce clean, shareable highlights with these settings. When you've captured a clip, post it to FragClips from the upload page, explore what others are making on the Explore feed, and find your game on the game pages.

Get your settings light, keep your game smooth, and start clipping. Your next highlight belongs on the upload page.
