Game is lagging so bad its unplayable

@Audigirl1  Thanks for the dxdiag, but I don't see anything obvious that would account for the lag.  I do see that Acer's registration software is crashing, so try disabling that in the Task Manager's Startup section.

For the Sims 4 issue, please try a new save and see how it goes.  If the new save also lags, please try a clean folder.  Move the 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.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just test another new save and let me know how it performs.

If even the new save in the clean folder lags, please look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of your most recent Sims 4 play session.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.

Hi, I'm having the same issue that OP is having. I tried what you said, but I wasn't able to find any errors at the time of gameplay. I've even tried chatting with someone at EA but it wasn't any kind of useful.

@SeleneSimblr  Please post a dxdiag.

Please also let me know whether the game lags in a new save with no mods or custom content present.

I took my original sims folder out and ran the game, it was still laggy but not as bad. Here's the DxDiag report.

@SeleneSimblr  Your laptop's processor and its graphics chip are below the minimum requirements for Sims 4.  That doesn't mean you can't play, but performance may be less than what you'd like.  There's no way to upgrade either component, so you're somewhat stuck here.

One thing you can try is forcing Sims 4 to use DirectX 11 rather than 9.  DX11 was only introduced with today's patch, and the implementation is a bit buggy from all appearances, but DX11 is better than 9 overall in terms of game performance.  There's no harm in trying it, anyway.  Here's how:

Please test in a new save with no mods or custom content, in one of the base game worlds, and let me know what you think.

I have the same issue, since the update, ive been trying EVERY solution to solve the problem of the lag, ive spend like 2 3 hours trying everytihing and nothing help so i gave up, i cant play it at all because of the lag and flickering and * 

@candle221  As a test, please try playing in a clean user folder.  Move the 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.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just start a new save and let me know how it runs.

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