If graphics tasks slow down your Mac
If your Mac notebook is slower than expected when you perform graphics-intensive tasks, such as playing games or editing video, open Battery preferences. Depending on your Mac, you may see options that let you improve graphics performance in exchange for shorter battery life.
On your Mac, choose Apple menu > System Preferences, click Battery, then click Battery or Power Adapter.
Deselect “Automatic graphics switching.”
Your Mac then always uses high-performance graphics.
Thanks for your feedback.
