Re: The game won't use my GPU
@Evergreenium Your dxdiag contains a few errors related to the Nvidia graphics driver, so the place to start is with a clean uninstall and reinstall of the driver.
Grab a fresh copy of the newest Nvidia driver:

The Intel graphics driver is also quite old, so it's a good idea to update that too. You can get the newest one here:
The order of operations here is to download both drivers, take your computer offline, run DDU to remove the Nvidia driver, restart, install the new Intel driver, restart, and install the Nvidia driver, then restart before trying to play. You'll also need to redo any settings in the Nvidia Control Panel.
