Running White Noise Shaders Smoothly on a Low-End PC

White Noise Shaders is built to run on low-end hardware and potato PCs without causing lag. If your framerate still dips, the problem is usually elsewhere in your setup, and the vanilla settings are the first place to look.

Check your base settings first

1. Open Options → Video Settings.

2. Lower Render Distance a step or two. This is the biggest performance factor in vanilla Minecraft, with or without shaders.

3. Reduce Simulation Distance if you're in singleplayer.

4. Set Clouds to Fast or Off, and turn down Particles.

5. Turn off V-Sync if your framerate feels capped or uneven, or turn it on if you see unwanted tearing. Keep in mind that this pack adds screen tear effects on purpose.

Make sure the pack itself is the one running

• Open Video Settings → Shader Packs and confirm White Noise Shaders is selected. If you leave a heavier pack active by mistake, you'll get lag that this pack isn't meant to cause.
• After switching packs, reload into your world so the new shaders fully compile.
• Close other heavy programs, such as browsers and video players, while you play.

The pack replaces standard graphics with noise and distortion instead of adding expensive realistic lighting. That makes it a good choice when other shader packs are too much for your machine.
