  2. Enable OpenGL for complex 3D visualizations
  3. Disable animations during rapid updates
  4. Use virtual series for datasets exceeding 100,000 points
  5. Implement downsampling for display optimization
  6. Batch updates using BeginUpdate/EndUpdate
  7. Use clipping to skip off-screen rendering
