CPU underclocking itself under load

I have a Lenovo Legion Y520-IKBM with i5-7300HQ, 1060 Max-Q and 16 GB RAM (I know it is a little bit weak for 2021). Recently I noticed that my CPU underclocks itself when it is under load. For example when I just browse the web or talk in discord the processor sits at around 3.20-3.30GHz, but when I start playing some heavy games like PUBG or COD the CPU just goes to 2.20-2.30GHz after 3-4 minutes of play time and the games don't run smoothly. I am using HW Info and saw that the laptop isn't thermalthrottling or anything like that. I also attached a HW info log, which was made while browsing the web. If someone can help me I would be thankful.

Your log does not show the issue. Base Clock is 2.5 GHz, so that's roughly what should be expected from the CPU under full load with optimal cooling.

Main: AMD Ryzen 7 2700X, Nvidia GTX 1080 Ti, 16 GB 3200 MHz DDR4 Fedora 35 x86_64

Secondary: Intel Xeon W3680, AMD Radeon HD 6950, 24 GB 1333 MHz DDR3 Windows 10 Home x86_64

Server: 2x Intel Xeon X5670, 72 GB 1333 MHz DDR3-R Ubuntu Server 20.04.1 LTS x86_64

Home Laptop: Intel Core i5-L16G7, 8 GB 4267 MHz LPDDR4x Windows 10 Home x86_64

Work Laptop: Intel Core i7-10510U, NVIDIA Quadro P520, 8 GB 2667 MHz DDR4 Windows 10 Pro x86_64

Here is a log while playing PUBG and talking in discord. You can clearly see when the base clock jumps down from 3.3GHz to 2.3GHz and i can't figure out why. When i turned the game off it immediately went back to 3.2GHz
