Windows 10: Maximum frequancy dropping from 170% to around 20% while playing games and it causes drops...

When i play games and my laptop is in high performance mode, maximum frequancy is dropping from 170 to 20% and goes back up and then after some time it goes down again , and like that in a loop. It has not happened before , it just started like 3 4 days ago so I don't know what to do and how can I fix that?IntelR CoreTM i7-8565U CPU @ 1.80GHz 1.99 GHzRAM 8.00 GB

Game frame drop

When I play a game for 20 minutes or less, my frame rate drops to 1-10 fps and I have to restart the game. I'm not sure what's causing this (counter strike global offensive)

 

Internet drops whenever I play a steam game

I'm having this weird issue on my new Laptop. Whenever I play a Steam game that's connected to the internet (e.g. Rocket League or Slay The Spire with Twitch Integration enabled) my internet seems to drop below 1 Mbit/s up and down. This seems to only affect my Laptop though. The Internet connection for e.g. my Phone is still stable. I'm using WiFi for both.
This seems to happen only for games I bought on Steam. However, I don't have to start them through Steam for my internet to drop. E.g. Starting Slay The Spire through the jar with Twitch Integration enabled also causes the internet to drop. If Twitch Integration is disabled, no drop happens.

Also testing with MoonLighter yielded the following result: Starting the game normally causes the internet to drop. However, if I block the Game in the Windows Firewall, the internet connection is unaffected if I open the game.

Speedtest on my Laptop with no Steam game open:

(26.7 Mbit/s down / 9.01 Mbit/s up)

Speedtest with RocketLeague open (Only in the Main Menu without joining a game):
Screenshot (0.53 Mbit/s down / 0.20 Mbit/s up)

After googling a bit I found this tip that states turning off flow control is a potential fix. This did not work for me.

My Laptop has two different Network adapters: Intel (R) Dual Band Wireless-AC 3165 and Realtek PCIe GBE Family Controller

If anyone knows a way to fix this or why it is happening please speak up. Help is greatly appreciated. Thanks in advance.

 

FPS drop in games

I saw also fps drops with some DX9 games at least since the anniversary update (I even did a fresh install but was the same), the only DX9 game that I play that had fps issues was 4Story (some had no changes, for example TERA, Final Fantasy XIII...), I usually
had 20-30fps minimum and it runs at 1fps or even lower.

The only way I found to play it was to change the d3d9.dll with the version of it before the anniversary update. A friend also had fps drops in CS:GO with w10 anniversary, so I think the problem is with that file and it should be fixed... There are posts
that talk about disabling Game DVR in the XBOX app, but since my computer does not meet the requirements I didn't test it.
