title: Unity Playmode low fps on Macbook m1
body: <p>I've have found a problem running unity(ver. 2019.4.34f1 and 2021.2.8f1) on my MacBook m1 chip. Whenever I run Playmode <em>while having Scene and Game tab open at the same time</em> I get only around 30fps which is very strange running on m1 chip. But When I <em>closed the Scene tab and ONLY having the Game tab open</em>, the fps jump to 400fps+.</p>
  <p>I have:</p>
  <ul>
  <li>installed mono, .Net Arm64</li>
  <li>Default Unity Configuration</li>
  </ul>
  <p>Is there a way to resolve this issue?</p>
