Reduce Lag Spikes During Sunset and Sunrise

Identify the Problem

Sunset and sunrise cause intensive lighting recalculations as the sun moves across the sky. This can create temporary frame rate drops even on capable systems.

Adjust Transition Settings

In Shader Options, look for settings related to:

• Sky Lighting Transitions: Reduce the smoothness of lighting changes during sunrise/sunset. Faster transitions mean fewer intermediate calculations.
• Ambient Light Updates: Lower the frequency of recalculation if available.
• Volumetric Effects: Disable or reduce god rays and atmospheric lighting during these times, as they're most intensive during transitions.

Lower Shadow Quality Temporarily

Shadow rendering intensifies during low-angle sun positions. Reduce shadow resolution or softness—the visual difference is less noticeable during transitions anyway.

Disable Advanced Features

Consider turning off:

• Screen-space reflections
• Advanced bloom effects
• Complex atmospheric scattering

Test the Fix

Monitor FPS stability. If lag persists, lower overall shader quality tier.
