Glitchy on fullscreen

@purimas3  Please run a dxdiag and attach it to a post.

Please also make sure that in fullscreen, you're actually running the game at your laptop screen's native resolution, which is probably 1920x1080, but check anyway.

Thank you for your reply, this is my dxdiag

@purimas3  Your dxdiag shows that a component of Nvidia GeForce Experience is crashing, so please uninstall it for now.   You can try reinstalling it later, once the game is working.  Please also manually reinstall DirectX 9, which is the faulting module in the Sims 4 crashes your dxdiag lists.  You don't need to uninstall it; just run the installer over the top and restart your computer.  If you haven't reinstalled a DX runtime before, please check this guide to make sure you're completing all the steps:

Finally, please make sure your computer is set to run Sims 4 in high-performance mode, which will also make sure it's using the Nvidia GPU at all times.  The screenshot you posted looks like what happens when Sims 4 meets an older Intel graphics driver.  Anyway, hit Windows key-i, select System > Display > Graphics settings, click Browse, choose TS4_x64.exe, select the high-performance option, and save.

Let  me know if none of this helps.  It might be worth updating the Intel driver, but it's also usually best to use the driver that a laptop manufacturer offers rather than anything newer.  So please try the other steps first.

Thank you for the respond. I already tried reinstalling NVIDIA drivers several times, including clean install with DDU in safe mode. I installed DX runtime too. The interesting part is.. i checked that The Sims 4 is already set to NVIDIA GPU (high performance), then i experimented using the Intel Iris Xe (power saving) instead. it run so great!. but it's kinda weird now i am using the integrated GPU instead of the more powerful dedicated one to play The Sims 4.

@purimas3  I actually thought it was worth updating the Intel driver, not the Nvidia one, since this problem has appeared with certain Intel graphics drivers a few times.  The problem could also be how the two drivers interact, but that would take some experimenting to diagnose.  Let me know if you'd like to try or want to troubleshoot further in general.

Update: I tried to connect my laptop with external monitor, and it works just fine, no screen glitch or anything. i wonder if my internal monitor compatibility is bad or what. with newer game (AAA ones) there is no problem with it tho.
