Big FPS. Video card overheating. Help with optimization.

Hello everyone. In the assembled project, it gives out 360 FPS, the video card gets very hot. In the editor, it gives out 170 FPS, it also heats up. I switch settings between fantastic and the fastest, there is no difference, it heats up the same way. If I artificially lower the FPS in the editor to 25-30 by moving the camera in the scene so that it loads the entire scene, then it does not heat up so much. If I take the camera outside the scene, then there is no load. What could it be?

Assembled project.

Turn on V-sync to limit your FPS to 60 and avoid overusing your GPU.

Also this: Unity - Scripting API: Application.targetFrameRate

 QualitySettings.vSyncCount = 0;
Application.targetFrameRate = 75;

This code helped a little, the video card keeps the temperature stable. But this is not a way out. My monitor works with a frequency of 75, the standard is 60, there are monitors that work with a frequency of 120. With this code, vertical synchronization is disabled. How can VSync be limited to 60 frames?
According to the schedule, at a certain moment, something loads the video card by 100%. By lowering the frequency, I simply lower the frequency of loading the video card.
How can you find out what loads the video card so much?

I tried to run a 3D game that was released a year ago, there is also a 60 frame limit. My project with the same restrictions performs slightly worse. So how to be?
