Luminous Swiftness Shaders FAQ
10 questions players actually ask, answered.
How do I turn on the shader after installing it?
Open your Video Settings, navigate to Shaders, and select Luminous Swiftness from the list. The shader will activate immediately and you'll see the visual changes in your world.
Why is my frame rate dropping even though this is supposed to be low-end?
Check your shadow intensity and water reflection settings—these have the biggest performance impact. Lowering shadow quality or disabling reflections in specific areas will improve frame rates on older systems.
Can I make the shadows darker or lighter?
Yes, use the shader settings menu to adjust shadow intensity. You can find this in Video Settings > Shaders > Shader Options while the pack is active.
The water looks weird or too reflective—how do I fix it?
Open the shader options and look for water reflection or water quality settings. You can reduce reflection intensity or disable reflections entirely if they're causing visual issues or lag.
How do I stop the grass and leaves from moving so much?
Access the shader options menu and find the foliage movement or waving effects slider. You can reduce it to a subtle sway or disable it completely depending on your preference.
Does this work with other mods like Optifine or Sodium?
Luminous Swiftness is designed as a standalone shader and may conflict with other optimization mods. Use it without Optifine or Sodium for the best compatibility and intended performance.
Can I use this shader in multiplayer or on servers?
Yes, shaders are client-side only, so they won't affect other players or cause server issues. Everyone sees your world through your own shader settings.
The sky colors look wrong at sunrise or sunset—can I customize them?
Open the shader options and look for sky color or time-of-day settings. You can adjust how the sky appears during different times to match your preferred aesthetic.
Will this shader work on my old laptop?
Luminous Swiftness is optimized for low-end systems, but very old laptops may still struggle. Start with shadow and reflection settings turned down, then gradually increase them until you find a balance between visuals and performance.
How do I uninstall or switch to a different shader?
Go to Video Settings > Shaders and select "None" to disable Luminous Swiftness, or choose a different shader pack from the list. Your world will return to vanilla visuals immediately.
