Calculating raymarching materials across block textures and casting sharp reflections over water bodies puts extra load on your graphics card. If your frame rate dips near oceans, rivers, or large polished builds, a few quick adjustments in your settings will smooth things out.
Adjusting Vanilla Video Settings
1. Open Options, go to Video Settings, and lower your Render Distance by two to four chunks. Fewer loaded chunks mean fewer block surfaces and water bodies being shaded at once.
2. Lower Simulation Distance and set Graphics or particle levels down a step if busy scenes still stutter.
3. If your shader loader exposes a separate shadow render distance slider on the shader selection screen, reduce it slightly while keeping nearby terrain crisp.
Tuning Shader Pack Settings
Open the Shaders or Shader Packs screen and click the settings button for Bloho Shaders if options are exposed by your loader. Look for quality controls tied to reflections, surface lighting, or materials and step them down one level at a time. Apply the changes and test your frame rate while looking across a wide body of water until performance feels responsive while retaining clear surface contrast.
