My Intel UHD graphics 620 is lagging, HELP

[Ayman1]

I bought an hp elitebook 830 g6 with this config:
Device name DESKTOP-RB59MCE
Processor Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz 2.11 GHz
Installed RAM 16.0 GB (15.8 GB usable)

And A Intel UHD graphics 620 which actually a good GPU.

BUT THE PROBLEM THAT I SEE LAG EVERYWHERE, WHEN READING A SIMPLE PDF FILE, or scrolling in spotify or anywhere.

I tried to reinstall the driver and even format all the computer so i can see if it can solve the issue, but it doesn't...

Hello Ayman1, 

Thank you for reaching out to us regarding the issue you’re experiencing with your graphics and game performance. To better assist you, I need to gather some additional information. Could you please answer the following questions? 

1. Can you please run the System Support Utility (SSU) and share the logs with me? 
2. How did you perform the last update? Did you use a device manager-clean installation or Display Driver Uninstaller (DDU) before updating to the latest graphics driver? 
3. Have you tried rolling back to the previous graphics driver version? 

Providing this information will help me diagnose the system more accurately and check for available solutions. Thank you for your cooperation, and I look forward to your response.
