@stacieokay12 Alright, it's worth getting your graphics chip recognized. It shouldn't matter, and usually skipping that step doesn't cause anything like what's in your screenshots, but you've tried most of the other fixes already.
Yyou're looking for a couple of files called graphicscards.sgr and graphicsrules.sgr, which are both located in the Sims 3 program files. For a Steaam install, the default file path is:
Program files (x86)\Steam\steamapps\common\The Sims 3\Game\Bin
Note: These instructions only apply to and will only work for the original poster's graphics card. If you'd like help getting your own card recognized, please post the same information from deviceconfig and ask for help.
Open graphicscards.sgr (Notepad works fine), and crtl-F to search for 8086. That will take you to these lines:
vendor "Intel" 0x8086
card 0x0042 "Havendale"
card 0x0046 "Havendale"
Create a new line under the "Intel" 0x8086 line, copy this text, and paste it in the new line:
card 0x8a56 "Intel UHD Graphics"
So you should now see this:
vendor "Intel" 0x8086
card 0x8a56 "Intel UHD Graphics"
card 0x0042 "Havendale"
card 0x0046 "Havendale"
(with indents from spaces that this site isn't displaying properly). Save, quit, and open graphicsrules.sgr. Crtl-F and search for Havendale, which will take you here:
if (match("${cardName}", "*Havendale*"))
seti cardLevel $cardLevelMedium
seti isCardMatched true
elseif (match("${cardName}", "*4?00*"))
Create a new line under the "true" in the third line above, and add this:
elseif (match("${cardName}", "*UHD Graphics*"))
seti cardLevel $cardLevelMedium
seti isCardMatched true
Add a tab before each seti, to match the formatting with the other entries. Save, quit, and delete options.ini, again, to allow the game to generate a new copy with the new default graphics profile.
Now launch the game and see how it looks. After you quit, please also check how deviceconfig.log lists your graphics chip, about 30 lines down. You should now see a [Found: 1, Matched: 1] next to the name.
Let me know both whether the game itself looks better and whether your graphics chip is now recognized.
