FPS drops when plugged in

[atmega88]

Hello,

I've recently got HP Pavilion -15 - cs3011nw and noticed strange behaviour: when laptop is plugged in graphics (Intel Iris Plus G7) performance drops. Meaning that when i play games (tested on League of Legends) occasionally FPS drops from 100 down to 5-10. This can also affect normal usage as I think I noticed similar issue when minimizing windows (small lag). None of this things happen when I unplug laptop and use battery. This issue is very similar to https://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/FPS-drop-when-plugged-in-and-charging.... I have tried:

• changing graphics settings (in game) to lowest
• changing graphics settings in Intel graphics centre for better performance
• changing power plan for better performance
• updating software (windows and graphics driver)
• updating BIOS (laptop came with F.03, updating to F.04 didn't help)

On battery power plan is set to medium, there are some power saving options set in Intel software and still it is able to run game on very high settings without a problem. Charger is original 45W that came with laptop.

Kind regards

I have gone through your Post and would like to help

Do you experience this issue with other Games as well? Does the Notebook meet the Game's requirements?

Please follow the steps listed below to improve the FPS on your Intel Graphics adapter: 

• Increase the amount of RAM - by increasing the shared memory under system properties > Advanced > Performance settings > Advanced > Change Virtual memory > use the recommended file size for paging. 

• Make sure the graphics card is not in power saving mode - If you are after maximum performance of you Intel HD Graphics, make sure you have turned off all of its power saving features. That is why in order to achieve maximum performance you have to make sure that your Windows power plan is not on Power Saver, you can use the Balanced or the High Performance power plan. You can also click the Intel HD Graphics driver tray icon (it should be near the clock in the taskbar), select Graphics Properties, then click the Power tab and select Maximum Performance. 
   
  Please, note that although this tip will certainly improve your Intel HD Graphics' performance it will also increase the power it draws, as well as the heat it generates under heavy load (which is the case for games). Caution is advised, especially if you are on a laptop that experiences temperature problems. 

• Set the 3D preference of Intel HD Graphics to "Performance" - This trick will help you improve the frame rate in games. To apply it click the Intel HD Graphics driver tray icon, select Graphics Properties, then click the 3D tab and move the slider to Performance. In this way, you sacrifice a bit of image quality for improved 3D performance, which should lead to a few more frames per second (FPS)
