That is just a small part of it, could you post the full DxDiag? It should be a txt file.

This:

Your graphics drivers are from 2016, try updating those:

You also have some crashes from HCLOUD.exe, which seems to be a Windows proces. Have you seen a notification of this before?

I actually attached an old DxDiag file. I'm up to date on my graphics. I think I've seen the HCloud problem before but would that really affect my games? I've played other games I have on my PC no problem. Like Assassin's Creed Origin and SimCity. Here is the more updated dxdiag attached.

That looks a lot better! I could be affecting it, if it's asking too much. You could try removing it by going to Start > Control Panel > Add/Remove programs.

Other than that your DxDiag looks good to me. Do you have any CC (Custom content) or mods? If so, could you try running the game without?

@bingsoo10  A 240Gb SSD is not big enough for a Windows gaming computer - Windows bloats that is what it does and 44.6Gb is not enough free space on the system device. You will continue to have issues and if you don't free up space the issues will get worse. TS3 is not like other 3D games. TS3 generates temp files more so then other games and you probably had more free space when playing other graphical games.

So I tried to look for the HCloud application but no where to be found in the control panel, program and features. I have no mods. I literally just got the game and the first ever boot up failed.

@roberta591 are you also talking about The Sims 4?

@bingsoo10 does the game run in full screen? Do you still hear the music playing?
