Grass looks like carpet at 1440p

It's already on default settings everything is set to off. I have a 7900 gre, it's not the card, because I also had it with my 4070

So go to Catalyst Control Center. Go to gaming and click the drop down. There should be an option called "Morphological Filtering". Disable it.

I'm on an AMD gpu

It does look there's some post-processing smoothing filter going on. The Sims has no antialiasing but everything in your image (including the walls) is smooth.

Can you try to:

1. Open Nvidia control panel
2. Go to Manage 3D settings
3. Turn off Antialiasing - FXAA

I'm on the latest version of windows 11

If you’re on windows 11 use windows key, left shift and S together and you can snip any part of your screen. Alternatively if you’re on windows 10 use snipping tool. The shortcut doesn’t work on windows 10

Yes, I used my phone to take the Picture I'll try print screen on PC if it works

It looks you've either applied an anti aliasing filter on the game or your phone camera applied a very strong noise reduction on the image.

Please post a proper screenshot here using your computer when you can.
