@havefeith Older AMD-based laptops often have a secondary graphics processor, essentially a low-powered graphics card that works in concert with the graphics chip integrated into the processor, that doesn't show up properly in the dxdiag. In your case, you can only see the 6620G, the chip integrated into your processor, listed in the dxdiag, but there's also a driver for the 6600M/6700M series present. That would be for the 6740M.
The driver for the 6740M is the newest AMD has, the only one available for Windows 10; Acer never made Windows 10 drivers for this laptop. It's possible the 2015 driver is the issue here, that it's too old to run Sims 4 properly, but that's difficult to say, and impossible to test since you can't install a newer driver. And even AMD didn't make a Windows 10 driver for the integrated chip—the one you have installed is a generic version from Microsoft.
Anyway, you can try forcing your system to use the 6740, that is if it's even an option. Click Windows key-i, select System > Display > Graphics settings, click Browse, choose TS4_x64.exe, click Options, and choose the high-powered option, then save the change. If that doesn't work, try the power-saving option.
You can also try running the Legacy Edition of Sims 4. It won't run any packs released after October 2019, but it's better than nothing.
