Re: Sims 3 not detecting GPU, despite modified configuration files
@szymon2512 Your laptop is actually missing the driver for the integrated graphics chip. The information for the RTX 3050 is further down in the dxdiag. It's normal for a dxdiag from a dual-GPU laptop to list the iGPU first, then the dedicated card, but I can see how that might be misleading if you didn't know what you were looking at.
Anyway, please install the AMD graphics driver listed here:
Restart after installing and before doing anything else. Even if Sims 3 doesn't necessarily need this, it will make other tasks that use the iGPU run a lot better.
