I just started my game after the latest update. I wanted to see if the default DX11 is active. There is supposed to be an option for enabling DX9 but I can't find it.
I play on windows 11 with a laptop that's less than two years old. I expect it is recent enough to handle DX11. In play the Dutch version of the game .
Edit: I have Nvidea gforce mx 450
It should be in the game options menu under graphics subcategory.
That's where I looked but couldn't find it.
atreya33 The option should be to the right of the Post Processing setting.
Having said that, the option isn't there at all for players who are still defaulted to DirectX 9. Is your game using DX9 or 11? You can check at the Main Menu, in the lower-right corner with the version number.
If you are using DX9, please check whether the game is using the Nvidia graphics card. Go into Documents > Electronic Arts > The Sims 4, open Config.log, scroll down about 30 lines, and let me know what GPU is listed there.
Gpu : 5 gpu memory : CPU: 3 ram CPU speed 2496 threading 3
tammyrp What issue are you seeing? And what you've posted isn't the information I was asking for. This is the beginning of Config.log; I want the Graphics Device Info about 30 lines down.
The number in the game ends on DX9 so I guess I am playing on DX9.
Here is a part of my config.cog. I have pasted the part about GPU but also the part below which does menstion NVidia

Is there a way to change this to DX11?
atreya33 It's possible that DX11 is only the default for Nvidia GTX/RTX graphics cards (and AMD GPUs), that MX chips are still defaulted to DX9. The documentation doesn't say so, but it would be unsurprising.
At any rate, to force DX11 mode, open the EA App game library, click Sims 4 > Manage > View properties, and add -dx11 to the command line box. Please remember that you've done this, as it will override any other potential changes you try to make.
puzzlezaddictI was mainly interested to see the difference between DX9 and DX11. The game seems to be still running fine so I can keep playing. I don't think I will force DX11 with a command line because I read that we are supposed to disable mods if we do that and I want to kee MCCC.
But what does this mean for the future? Will I be moved to DX11 on a later patch? Or will my game stop working then?
By the way my computer has DX12, so doesn't that imply that all DX11 programs can run as well?
atreya33 DirectX 9 is older than DX11 and as such, has fewer features, especially features that newer programs and newer hardware can use to run better. If you'd like to know more about what DirectX does, please see this:
https://en.wikipedia.org/wiki/DirectX
In general, there's a difference between "the sytem is compatible with and can run this software" and "the software is optimized for this OS or hardware." I don't know what's going on under the hood with Sims 4, but I would guess that DX11 mode has only been optimized for newer Nvidia and AMD GPUs to target higher-end gaming systems. I believe that any computer that can currently run Sims 4 also supports DX11, but that doesn't mean that this implementation of DX11 (as in what Sims 4 is doing) works with any system that supports the API in general.
I would guess that DX9 mode will be around for a while, at least until Maxis is satisfied with how DX11 mode works on any system it cares to support. (I don't know how long that would be, and whether it would end up like the Legacy Edition—opt-in for anyone as long as it exists—or only available to some users.) And I'm reasonably sure your computer can handle DX11 mode; the question is whether performance would be better or worse than in DX9 mode.
And yes, the fact that your system supports DX12 means it can also run DX11.
I took this from the update notes for Sep 18. It looks like the first link should give detailed instructions for using DX11 on systems that don't use it by default.
"For detailed information about DirectX 11 and instructions on how to enter launch arguments for both the EA App and Steam, please visit here. If you encounter any issues with DirectX, you can find assistance here."
