Unity does not use a high-performance graphic card on macOS 10.15.1?

I am using Unity on MacBook Pros Catalina (10.15.1) installed. However, it seems that Unity does not use a high-performance graphics card regardless of whether I turn automatic switching on or off, even if I designated a GPU device in the Unity's preference menu.

The first image below shows the case when the automatic GPU switching on. As shown here, Unity uses an integrated GPU.

The second image below shows the case when the automatic GPU switching off. Even in this case, it does not seem that Unity is using a high-performance one considering the Graphics Card column of the unity processors shows No for all. But in this case, I am not too sure if Unity is actually using a high-performance GPU although it says no on Activity Monitor. However, I am not positive about this considering that the Unity editor's performance is the same as the case of an integrated card.



[with automatic graphics switching off]

I tested this issue with two machines, MBP 15" with Radeon 560 and MPT 16" with Radeon 5500M, and both machines exhibited the same behavior.

[As a comparison, Adobe Illustrator works as expected]

As a comparison, all other apps, such as Illustrator or Photoshop, that are supposed to use a high-performance graphics card behave as expected. Even when the automatic switching is on, they run on a high-performance graphics card and Activity Monitor shows they are actually using it.

Is this a normal behavior that is expected? If so, is there any way that I can use a high-performance GPU for Unity with an automatic switching option enabled? I do not want to use a high-performance GPU all the time, so it will be best if Unity can automatically use a high-performance GPU when it runs.

Any input will be greatly appreciated.

 

I have run into the same problem... tested with both 2019.2 and 2019.3.

With the VFX Graph running, the editor seems to be glitching out a bit too (why I looked into what GPU it was using)... and finding a solution for this would be good.
