Re: Re: UHD 620 vs AMD Radeon Vega 8

@NicoleMcC25  There could be any number of issues with Sims 3, from the Pets expansion being too demanding for your graphics chip to save corruption.

Please move the entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just start a new save in Sunset Valley and let me know how it runs.

Please also run a dxdiag and attach it to a post.

Edit:  I've merged your two posts and created a new thread for you in the Sims 3 section so we can keep everything in one place.
