Unlike heavy realistic shader packs that add expensive shadows and water reflections, NMS Normal Map Shaders is built to run fast on older computers and low-end hardware. You can pair it with sensible vanilla video settings to keep framerates high while enjoying the colorful normal map display.
Adjusting Vanilla Video Settings
Even with a lightweight shader active, your base game settings still control how much geometry your computer has to draw.
1. Press Esc and open Options > Video Settings.
2. Lower your Render Distance and Simulation Distance until frame stutters disappear when loading new chunks.
3. Set Graphics to Fast so leaves and weather effects require less processing power.
4. Turn Entity Shadows off and reduce Particles to Decreased or Minimal.
Checking Performance in Busy Areas
Because the shader colors blocks, items, and mobs based on their surface directions, areas packed with chests, item frames, or animal farms still require your system to process every visible model.
1. Press F3 in game to view your current framerate in the top-left corner.
2. Walk through mob-heavy or build-dense areas to verify your framerate stays comfortable.
3. If slowdowns occur around large farms, lower Entity Distance in your video settings so distant mobs stop rendering early.
