Radiant Amber Glow is built to run smoothly on low-end, potato, and mid-range hardware without draining system resources. If your frame rate still dips during heavy gameplay or chunk loading, pairing the shader's lightweight design with sensible vanilla video settings will stabilize performance.
Balancing Vanilla Video Settings
Because shaders process lighting across every visible chunk across all biomes, vanilla distance sliders have the biggest impact on frame rates:
1. Open Options > Video Settings.
2. Lower your Render Distance and Simulation Distance by a few chunks until frame pacing feels steady.
3. Set Entity Shadows or excess particle effects lower if busy mob farms cause stutter, letting the shader's own soft landscape shadows handle the atmosphere.
Tuning Shader Pack Options
Most shader loaders let you adjust internal pack features without switching packs altogether:
1. Navigate to Video Settings > Shaders.
2. Open the Shader Pack Settings menu (usually located in the bottom-right corner in OptiFine or top-right in Iris).
3. Browse the available profile presets or lighting and shadow menus.
4. Step down shadow resolution or bloom intensity one notch at a time if your integrated graphics struggle during sunrise or sunset transitions.
Click Apply or Done and test your frame rate while sprinting through dense forest or mountain biomes.
