Artifacting on Macs with AMD GPUs or M1 chips

See those dark lines running through the leaves of the bush (first image) and upper half of the floor texture (second image)? This happens on every lot in every world in all my saves. It appears on certain objects, foundations, floors, etc. It also happens with certain CAS items (clothing items with reflective textures specifically). I should also note this issue has persisted for several months through at least 3 patches.

I've tried the following:

- deleting options.ini

- running my game without mods

- turning off v-sync

- turning off post processing effects

- changing resolution

- playing in windowed mode

I'm playing with Ultra graphics settings

and my computer specs are as follows

2019 iMac

3 GHz 6-Core Intel Core i5

32 GB 2667 MHz DDR4

Radeon Pro 570X 4 GB

Retina 5K Display

MacOS Catalina 10.15.4

Any suggestions would be helpful 🙂

Ah that sucks. Thanks for your help!

Hi All.  Just thought I'd bump this thread by pointing out that I have this issue too and have had it at least since late 2019 (this is the first time I could find anyone reporting the issue, so pardon my tardiness!) I too have the little lines appearing in direct sunlight, which is visible in my stop motion build videos (on Youtube under username xoxDahlia) and experienced them even when I didn't have any CC in my game.  Here are my specs—looks like the issue isn't isolated to AMD graphics cards.

Macbook Pro (13-inch, 2016)

2 GHz Dual-Core Intel Core i5

8 GB 1867 MHz LPDDR3

Intel Iris Graphics 540 1536 MB

I've tried all the repairs, redownloads, etc. to no avail, and I'm running the latest OS Catalina 10.15.6 so my drivers are (in theory) fully updated. I've also set SSAO to false in GraphicsRules.ini so I know it's not related to that.  If I had to guess, I'd say it has something to do with the interaction between Sims 4 and Mac-specific graphics drivers, possibly Metal-related, but good to know I'm not the only one with this issue.

It would be really awesome if EA could patch this the way they did with the box shadow effect under sims.  🙂

Hi @Bluebellflora 

Thanks for that.  I've attached some screenshots of the little lines on a plant and foundation in afternoon sunlight.  I'll also attach photos of the same plant and foundation after turning off RenderShadowsEnabled, just for interest's sake.  It solved the line glitch, but as you mentioned before in this thread, I'd rather deal with some lines than lose all shadows.  (Sad we have to choose, right?)

Hope this is helpful!

Cheers

As per above, after shots attached.

It is affecting Windows users too - https://answers.ea.com/t5/Bug-Reports/Weird-texture-lines-on-some-objects-when-hit-by-direct-light/m-p/9812011

I also have it on my MacBook Air with M1:

I thought it may be a hardware issue with AMD GPUs but my air doesn't have an AMD, even though the Config.log thinks it is:
