Sunset_Gossip Open the Bin folder inside the game's program files, here by default for an EA App or Origin or Steam install, respectively:
Program Files\EA Games\The Sims 3\Game\Bin
Program Files (x86)\Origin Games\The Sims 3\Game\Bin
Program Files (x86)\Steam\steamapps\common\The Sims 3\Game\Bin
First, open graphicscards.sgr (Notepad is fine). Click crtl-F and search for 10de , which will bring you to these lines:
vendor "NVIDIA" 0x10b4 0x12d2 0x10de
card 0x0fd1 "GeForce GT 650M"
card 0x0fd2 "GeForce GT 640M"
Create a new line under the one that says Nvidia and copy and paste this:
card 0x2489 "GeForce RTX 3060 Ti"
Make sure this line is indented like the ones below it; the lines in my copy are one Tab in from the left. Save, close the file, and open graphicsrules.sgr. Search for 8800 , which will take you here:
elseif (match("${cardName}", "*8800*") or match("${cardName}", "*9500*") or match("${cardName}", [etc.]
Change the bolded 8800 to 3060 , but don't change or delete any of the other characters, not even the asterisks. This will designate your card as uber-level, as it should be.
Finally, scroll to the top of the file and find this, 8-10 lines down:
if ($textureMemory == 0)
seti textureMemory 32
setb textureMemorySizeOK false
Change the 32 to a 1024 and put a # and a space in front of setb (and leave the other spaces on the left intact). This will tell the game your graphics card has 1 GB VRAM instead of none. It has a lot more than that, but Sims 3 can only use 800 MB anyway.
Save, close the file, load the game, quit, and check deviceconfig again. You should see a [Found: 1, Matched: 1] next to your graphics card's name, and a few lines down, the "texture memory" (VRAM) should read 1024 instead of 32.
If this doesn't work, please post the same section of the deviceconfig as you did this time.
