Graphics Card Not Recognised by TS4

IncomingNazgul​  That was part of why I suggested the new, local, admin Windows account.  No linked email means no OneDrive in addition to fresh user settings.  I'm glad you addressed that part.

For the unrecognized graphics card, open [install location]\The Sims 4\Game\Bin, here by default:

C:\Program Files\EA Games\The Sims 4\Game\Bin

Copy GraphicsCards.sgr and paste it into Documents\Electronic Arts\The Sims 4\ConfigOverride.  The point is that this copy won't get reverted to the original the next time you update or repair the game.  Open the file, click ctrl-F and search for intel , and you'll land here:

vendor "Intel" 0x8086
    card    0x2A42  "Intel® Graphics Media Accelerator 4500"    $cardLevelLow   $resolutionLow  unsupportedMac

Create a new line under the Intel one, indent it to match the one above (looks like four spaces on my end), and add this line:

vendor "Intel" 0x8086
    card    0x46A6  "Intel Iris Xe Graphics"    $cardLevelHigh   $resolutionHigh

Save the change, close the file, launch the game, quit, and check Config.log again.  Your should see [Found: 1, Supported: 1] in the graphics section.
