[CURRENT ISSUE] Freezing, possible system lockup on Macs with AMD Vega GPUs

I tried windowed mode and it was actually more unstable.

My resolution is currently set to 2560x1440 (first option available for me). I did play around with other resolutions last week but the display looks horrible so I never played on them for very long. 

Yes, but it's already on the lowest available setting, does that matter? 

Sorry, just want to make sure I am doing this correctly, I am currently on the lowest setting of 2560x1440. I have higher resolution options and when toying with things last week tried them out but the settings were horrible so I've been back down to the default/lowest setting.

Also when I did windowed mode it almost immediately locked up. 

Ok see attached - just wanted to include everything.

Yes so when I was running Catalina, I couldn't toggle back to the desktop ever. I would still have a moveable pointer and could hear the Sims music playing though. The only way to move forward was a forced shut down.

Since the Big Sur upgrade I can at least toggle back to the desktop and force quit. I did try to leave it for 10-15 minutes to see if the game would officially crash out but it never does, so force quit it is.

here's what I got 

@Bluebellflora sure, but it keeps deleting itself? is there a special way to post it? not sure how to do that little gray box thing

Click on the Insert Code option and you should get a pop up to c/p into 🙂

got it! thanks! here you go

Hello, 

I've been experiencing the same issues since the September patch, posted this like a month ago on this forum (this or a merged thread). I must say, I'm still experiencing the issues, but my game is not completely unplayable. I've noticed the game lags a little first and only when I continue (and especially spin my camera more or very fast) it freezes.

I have a habit of saving my game a lot (I've had this habit for years, since I had an issue when my Sims 4 game crashed every time a time machine backup was initiated). 

But most importantly, I spin my camera very slowly now... Every time the game lags a little bit when spinning the camera, I save and restart. It's sad of course that I have to adjust and interrupt my gameplay because of a stupid bug, but hey... This way, I'm still enjoying my game :-)

Of course, whether it's an issue on EA's end or Apples end, I hope someone discovers what's causing this freezing thing and it gets fixed either by EA or Apple...

And as a reminder, my specs:

iMac (Retina 4K, 21.5-inch, 2019)

macOS Catalina version 10.15.7 (19H2)

Processor: 3,2 GHz 6-Core Intel Core i7

Memory: 32 GB 2667 MHz DDR4

Graphic card: Radeon Pro Vega 20 4 GB

I do the same thing, many saves and restarts, but I can’t get 20-30 minutes without a camera angle change (or zoom in) to eventually lead to a full freeze. Sometimes the first few times I get the spinning wheel and it unfreezes itself, but it always progresses to a full freeze the next time. 

Yesterday I tried and I got a full game freeze immediately upon loading a lot and zooming in. 

Just PMed you a DropBox link.

Just a thought... Because I was just having lots of freezing on a particular lot in my save...

Could this issue maybe have something to do with the new way the game treats/calculates windows and doors? That broke cc windows for one, but maybe the calculations (or something way too technical for me, I don't know much about this stuff tbh) the game now makes, somehow mess up the way the graphics cards in our iMacs work? I dunno...

The lot I was having the issues with (save file I sent to @Bluebellflora ) is a lot with cc windows that I 'fixed' for the time being by placing Basegame windows on top of them with bb.moveobjects on.

@znijnz Definitely goes along with an earlier theory that something in the the more recent patches is triggering this to happen. If only they could figure out what. I don’t know coding or technology either but I personally have never had a game just not work like this. Even sims 3 wouldn’t do this particular problem to my Mac which is so bizarre to me. 

Update from today’s attempt to play. 

I’ve been staying away from the game in some hopes maybe it will fix itself (silly I know) 

but this is interesting, and still bizarre but today my game gave me the rainbow wheel, red screen, then pixelated screen but much to my surprise fixed itself as in my game came back on screen and worked for a moment but then another rainbow wheel came and completely froze. 

I feel like my game wants to work but something is holding it back!
