Re: Sims 3 white lines
@Bts152 Please disable Game Mode and Game Bar, both features of Windows 10. You can reach the settings for each feature by hitting Windows key-i and choosing Gaming.
If that doesn't help, please go into Documents\Electronic Arts\The Sims 3, open the file labeled deviceconfig.log, copy the first 40 or so lines (stop where "Options" starts), and paste them here. This will show how the game is reading your hardware. The file lists your user and machine names about 25 lines down, but there's no other personal information.
