i really need help my sims 3 is so laggy

@katelynwstxoxo  The dxdiag doesn't show whether Razer Cortex is installed or not; it just reports on recent Windows errors.  That's how I could see that Cortex was crashing.  There are no new errors in this dxdiag, just the same list as last time.

I mentioned this before, but please make sure you're playing only while the laptop is plugged in and charging.  Running it while on battery will throttle performance.

Please also go into Documents > Electronic Arts > The Sims 3, open the deviceconfig file, copy the first 40 or so lines (stop when you get to "Options"), and paste that info here.  This will show how the game sees and rates your hardware.  You can delete your computer and user names, about 20 lines down, if you want; the file doesn't contain any other personal information.
