Unlike realistic lighting packs, ReAlexey Shaders has no heavy graphics requirements and is built to run on low-end potato computers. However, pairing it with sensible vanilla video settings ensures your frame rate stays completely responsive.
Adjusting Vanilla Video Settings
Even with a lightweight joke shader, base game settings still control your overall performance. If you notice any stutter after enabling the portrait effect, adjust your standard options:
1. Open Options > Video Settings.
2. Lower your Render Distance and Simulation Distance so your computer processes fewer chunks at once.
3. Change Graphics from Fabulous or Fancy down to Fast.
4. Turn Entity Shadows off and reduce Particles to Decreased or Minimal.
Checking Screen Resolution Impact
Because ReAlexey Shaders replaces pixels on your screen with repeating portrait textures, running Minecraft at a very high monitor resolution still forces weak integrated graphics to push more total pixels.
1. In Video Settings, locate the Fullscreen Resolution slider.
2. Step the resolution down to a standard lower setting while keeping fullscreen active.
3. Return to your world to enjoy the cursed portrait visuals at a much smoother frame rate.
