Re: Sims 3 refuses to launch Windows 11
@DamienBlackCross Does your computer have a 12th-gen Intel processor? If so, that's the issue: Sims 3 doesn't start correctly on these CPUs. The workaround is limiting the game to one CPU core as it starts loading. Please see the accepted solution on page one of this thread:
If your computer has a different processor, or you're not sure what it has, please run a dxdiag and attach it to a post.
