A tutorial where you can see why MTLCompilerService uses significant resources CPU and what is this process on macOS. In what situations does it start running and how can it be stopped.
When a Mac or MacBook it gets noisy, it's best to check in immediately Activity Monitor, and see which application or process is using significant CPU resources.
MTLCompilerService it can be one of the processes that make it difficult for the operations on macOS and make the cooling system audible.

What is a MTLCompilerService
MTLCompilerService is a process on macOS which belongs to the framework Metal. It is used for graphics and data processing on video cards. This process is responsible for compiling the shaders (special programs for the video card) that are used by the applications running on the Mac. Therefore, it is not a process of a malware application that has infected the Mac.
Shaders are programmed to perform complex calculations on the input data so that the video card can display real-time graphics and perform other graphics processing tasks.
Why MTLCompilerService uses significant CPU resources
When you have graphic editing software applications open and there are complex files in them that require advanced processing, it is very possible to see that MTLCompilerService uses significant CPU resources. It means that at that moment, graphic or video editing applications use the framework intensively Metal.
It can be seen in the image above, an almost 100% use of the CPU.
In this situation, the problem was caused by many complex files in progress, open the application Adobe Photoshop. This application uses the framework Metal to display graphics in real time and to speed up photo and graphics editing processes.
Here are some other applications because of which MTLCompilerService uses significant resources CPU:
Final Cut Pro X – Video editing program developed by Apple, use the framework Metal to speed up video processing processes and to display real-time video previews.
Blender si Maya use the framework Metal to speed up the modeling and display processes of complex 3D models.
Games they can also cause an excessive consumption of CPU resources by the process MTLCompilerService. Lots of games on macOS use the framework Metal to display graphics 3D high quality and to speed up the calculation and physics processes of the game.
In conclusion, the size and complexity of the input data used by these graphic and video editing applications can have a significant impact on the use of resources CPU by MTLCompilerService.
