Re: My sims 4 is laggy in gamemode and buildmode

@lincarlssonnea  Please test a new save in a clean user folder for the sake of comparison.  Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and 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 and let me know how it runs.

If you don't see any lag, copy your existing svae from the old Sims 4 folder to the new one, but don't move over anything else, at least not yet.  If that save runs fine too, you can start adding your mods and custom content or anything else you'd like to keep.

If the new save lags too, please run a dxdiag and attach it to a post.
