Serious lag/loading issues

jgall19  Your dxdiag lists a handful of generic Windows errors, so please run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

Please also disable Game Mode and Game Bar, both under Windows Settings > Gaming.

Finally, please update the driver for your Nvidia graphics card.  The newest-available driver is still somewhat old, but it's newer than your current one, so it may help.  Go here:

Select GeForce, GeForce 700M Series (Notebooks), GT 720M [make sure GT is showing], Windows 10, and download the Game Ready Driver from 2019.  Run the installer as an admin: right-click the download and select "Run as administrator."  Restart your computer afterwards and before trying to play.
