Ephyrium Shaders is built to balance semi-realistic visuals with smooth gameplay, but busy player builds, wide water bodies, and long view distances can still push hardware limits. You can recover performance in a few quick steps without turning shaders off.
Lowering the Shader Profile First
1. Pause the game and go to Options > Video Settings > Shaders.
2. Open the pack's settings menu and change the active profile from High down to Medium.
3. Confirm the change and walk around a dense area of your base to test how smoothly the camera pans.
Pairing Vanilla Settings with the Shader
Detailed shadows are cast across terrain, water surfaces, and player builds inside your loaded area, which means vanilla distance sliders directly affect how much work Ephyrium Shaders has to do.
1. Open Video Settings and lower Render Distance by two to four chunks at a time until stuttering stops.
2. If your loader exposes a separate Shadow Distance slider, pull it slightly below your render distance so distant hills do not draw unnecessary shadows.
3. Turn down Simulation Distance when playing in singleplayer near mob farms or villages.
4. Keep Ephyrium Shaders enabled throughout these tweaks—even on the medium profile, you still retain soft bloom around light sources, clear blocks during the day, and sharp visibility at night.
