Step 2: Optimize BSL Shaders for Low FPS Fix

Now that BSL Shaders is installed, we need to adjust the settings for higher FPS while keeping good visuals.

1. Lower Shader Settings

• Render Quality: 0.7x

2. Adjust Video Settings

Go to Options > Video Settings, and set:

• Graphics: Fast
• Render Distance: 6-8 Chunks
• Smooth Lighting: OFF
• VSync: OFF
• Bobbing: OFF
• Clouds: OFF
• Particles: Minimal

3. Turn Off Unnecessary Effects

In Shader Settings, disable:

These tweaks will dramatically improve FPS on low-end PCs!

Step 3: Test FPS & Make Final Adjustments

Once you’ve optimized BSL Shaders, restart Minecraft and test your FPS using:

• F3 Menu: Press F3 to check FPS in the top-left corner.
• Try different areas: Some biomes (like forests) are more demanding.

• If FPS is still low:
• Lower Render Distance even more.
• Reduce Shadow Quality to 0.3x.
