Calculating realistic surface reflections, material properties, and physics-based light bounces puts extra work on your graphics card. You can pair Pure PBR Shaders with compatible textures and adjust your settings to balance visual detail with smooth frame rates.
Pairing with Resource Packs
Pure PBR Shaders gives blocks accurate surface properties on its own, so it works right away with default Minecraft textures. If you also want to use a PBR-compatible resource pack:
1. Place the texture pack inside your resourcepacks folder and enable it in Options > Resource Packs.
2. Open Options > Video Settings > Shaders, enter the shader pack's settings menu, and check that any surface or material reflection options match your active resource pack.
Improving Frame Rates Without Losing Material Detail
If wide outdoor landscapes or rainy weather lower your performance while the shader calculates wet surfaces and light bounces, tune your settings in this order:
- Lower Render Distance first: Reducing vanilla Render Distance cuts down the amount of outdoor terrain and sky light distribution calculated every frame.
- Adjust shader pack options: Open the shader's configuration screen inside the Shaders menu and step down reflection, shadow, or light bounce quality settings until camera movement feels smooth.
