XPS models GPU and CPU throttling OFF :)))

This will increase the performance in games and removes friezes. In this case, the temperature will remain the same and there will be no overheating! The fact is that Dell has set up throttling in such a way that it starts working at low temperatures for a short time. Because of this, playing games is uncomfortable. But it can be turned off. It is necessary to remove Intel Dynamic Platform And Thermal devices having the ID ACPI \ VEN_INT & DEV_3403. First you need to disable the automatic installation of devices with this ID in the group policy editor.

1 Push Win + R write gpedit.msc (working only windows 10 PRO)

2 Run Administrative Templates\System\Device Installation\Device Installation Restrictions\Prevent the installation of devices with the specified device codes - double click - switched-on - below the "show" button and write in the free field ACPI \ VEN_INT & DEV_3403 (This must be done in order for Windows not to install these devices.)

3 Open the device manager and remove all Intel Dynamic Platform And Thermal devices having the ID ACPI \ VEN_INT & DEV_3403 (there should be 6 of them.)

4 Reboot the computer go to the device manager and should be reflected 6 unknown devices. It is they who limit the frequency of your Hardware.

I render video and play games and my laptop XPS 9575 temperature does not exceed 86 degrees Celsius.This is a very good indicator and you should not worry about overheating. But I recommend turning off the processor turboboost when you play games. It does not affect the FPS but raises the temperature. I see no reason to use it in games. Watch the temperatures and if your hardware can not be heated above 90-95 degrees Celsius then everything is fine.
This method should work on all laptops. I used it on the following models: Dell XPS 9575, Inspiron 7567 and Xiaomi Air 2018.
