Sims 3 doesn't run properly on my GeForce GTX 970 video card

Hello!

The Sims 3 doesn't run properly on my new high end gaming PC. The game runs very laggy.

Before I decided to post this thread, I tried several popular solutions, but they didn't solve the issue completely.

First and foremost here is my DxDiag report:

When I first installed the game, it told me that it didn't recognize my video card.

Then I searched for a solution, and I did this:

http://simswiki.info/wiki.php?title=Game_Help:Getting_new_graphics_cards_recognized_by_the_game

I did all the steps and the game recognized my card, but the issue persisted - the game was laggy and choppy.

After that when I checked the DeviceConfig file, I noticed that my GPU Memory rating was 1. Then I tried making this change in the GraphicsRules.sgr file:

seti gpumemLevelUber 4
seti gpumemLevelHigh 4
seti gpumemLevelMedium 4
seti gpumemLevelLow 4

The GPU Memory rating changed to 4, but the issue persisted again.

Then in the DeviceConfig file I noticed this line:

"Texture memory: 32MB <<OVERRIDE>>"

This is ridicules, since my video card has 4 GB of memory. I compared the DeviceConfig file on my laptop (that has a vastly inferior graphics card), where the game works just fine, and on that line the memory was 1696 MB.

Here is the current status of my DeviceConfig file:

I also have 2 graphics cards:

1) NVIDIA GeForce GTX 970
2) Intel(R) HD Graphics 4600

I think that maybe the game tries to use the Intel card? I tried tinkering with the Nvidia Control Panel, but that didn't do anything

I kept googling my issue and I'm now stuck. So I decided to post here.

Can you guys help me to get the game working properly?

Thanks in advance!
