Windows 10: Why is my pc lagging so much?

I have an Nvidia 2060 super, 16 gb ddr4 ram. Im running windows 11, my antivirus app cant find anything, my graphic card drivers are up to date. But as soon i start for example Rainbow six siege, its absolutely unplayable, im getting like +/- 10 fps, and sometimes 60. I had previously played easily 120+ fps with very good graphics. I have a lot space on my ssd cards. It played games like red dead redemption 2 with very good graphics easily, and almost got to play every game +120 fps.

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

Windows 10 lags

Hi,



Thank you for writing to Microsoft Community Forums.



We understand how difficult it is when the PC doesn’t perform the way it should be. We were checking the lag issue, but
in order to get clarity and to assist you accordingly, please reply with the answers to the questions below.

• What is the Windows 10 version and Build installed? (Type
  winver in Windows search/Run command)
  
• How much is the CPU and Disk usage showing in Task Manager, also check if any particular program is having high CPU and Disk usage?

We would suggest you to refer the steps as suggested in this article (Exclude step 10):
Tips to improve PC performance in Windows 10



Meanwhile, put the PC in Clean Boot and see if you still get the PC lagging issue. Refer the article

How to perform a clean boot in Windows. A ‘clean boot’ starts Windows with a minimal set of drivers and startup programs. If the settings app is working fine in Clean Boot then please refer the section
How to determine what is causing the problem after you do a clean boot
to determine the root cause of the issue.



Note: After you finish troubleshooting, follow the section
Reset the computer to start normally after clean boot troubleshooting
to reset the computer to start normally.
