@Pooka20 Asus support is wrong. Frankly, even if it were true, that would be an incredibly shoddy result for a gaming laptop that is heavily marketed as such. I'd love to speak to that support rep myself and share some thoughts, but suffice it to say that that statement is categorically incorrect and also totally irresponsible. Now if Asus wants to give you a full refund so you can go buy something else, that's fine. But making up a bad answer and punting is not the way to go.
Your config file shows the Xe chip isn't recognized. I triple-checked my work before uploading the GraphicsCards.sgr file, but I checked it again just now to be sure, and the device ID is in the file. So there are a few possibilities here. One is that you didn't remove the - sign from the file. Please double-check that and that the file name is properly capitalized. Another possibility is that you added the .sgr file to the wrong ConfigOverride folder, not the one the game is reading. Please make sure it's in the correct folder; here's how to find it:

Finally, you'll have needed to launch Sims 4 once after adding the .sgr file to ConfigOverride, and you'll need to look at the Config.log that's in the proper user folder, again the one in the file path the game provides.
