Sims 4 Lag with new Graphics card

[michaela981]

I recently upgraded my graphics card from an AMD Radeon RX 580R

after it blew, to a NVIDIA RTX 2080

After the upgrade I did a windows refresh and used DDU to make sure AMD drivers were gone and have confirmed the NVIDIA drivers were installed correctly. Ever since this upgrade, Sims 4 claims the graphics card was not recognised and the game runs poorly. Stuttering, lagging. Low FPS.  Etc 

I know it's using the NVIDIA card because the task manager displays it's using GPU 0 NVIDIA. 

I have 16GB RAM

i7-7600K

850W PSU

Hardware wise I'm fine. All other games run fine. It's just Sims 4 being weird.

Please try to start the game in windowed mode as explained here: https://sims4.crinrict.com/en/2014/02/start-game-in-windowed-mode/

Do you have a screenshot of the error message? I believe there are two separate messages for unrecognised cards in Windows.

You could try manually adding your GPU to the GraphicsCards.sgr file. Do you know the Device ID of your card? You can find it in the DxDiag of your machine:

Device Key: Enum\PCI\VEN_10DE&DEV_1B81&SUBSYS_33011462&REV_A1

The bits in bold and red.

Let me know if you'd like to add it and I can help you if you need it

Windowed mode makes no difference.

The error message just says the card was not recognised.

On DXDiag there is no Device Key mentioned. All it mentions  on Display Tab is

Name: NVIDIA GeForce RTX 2080

Manufacturer: NVIDIA
Chip: GeForce RTX 2080

DAC: Integrated RAMDAC
Device Type: FullDisplay Device

Total Mem: 16174MB
VRAM: 8010MB
Shared Mem: 8164MB

Ok. There are instructions on NVIDIA's site on how to find your Device ID here - https://nvidia.custhelp.com/app/answers/detail/a_id/2040/~/identifying-the-graphics-card-model-and-d...

DeviceID: 10DE 1E87 37A71458

Great, thanks You need to add the following line to your GraphicsCards.sgr file:

0x1E87 "NVIDIA GeForce RTX 2080" $cardLevelUber $resolutionHigh

- Locate the GraphicsCards.sgr file here, make a backup of it, and open it in Notepad - Program files(x86) > Origin games > The Sims 4 > Game > bin

- Add the line under the NVIDIA section so it looks like this:

Save and quit then open your game and see how it plays. Close the game and open the Config.log file in Documents > Electronic Arts > The Sims 4. Near the top under === Graphics device info === check the Found and Supported values are 1.

Okay I've done it and I'm testing it. Should it  make the game perform better? Since it's onlysince getting the card not  recognised has the games performance been janky.

@michaela981

Yes, it should Check the Found and Supported after closing the game too.

[michaela981]

How do you check?

The game still stutters but not as much as it did.
