Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Slowness on MacOS since October 1 update

Is anyone else seeing slowness on Mac since the update rolled out on October 1st? No changes to my Macbook Pro M1 Max or graphics settings. I rebooted, etc.

Build 15891153

Sonoma 14.7

The lag/framerate in Act 3 is terrible.

You saying a new game started after the hotfix 27 runs slow in act 3?

Patch 7 and hotfix 27 was made available for MacOS yesterday. When I resumed my honor mode game in Act 3 I noticed it was very laggy. I tried rebooting and it was still the same. The day(s) before the patch/hotfix there were no such issues.

Submitted a bug report.

yes your old save was made with patch 6 then... which will be why

I saved and rebooted and that didn't help at all.

I have exactly the same issue. Sonoma 14.7 + MBP M3 Max. I loaded an Act 3 save game (saved with Patch 6 of course). I quit the game multiple times, re-enabled High-Power mode on the Mac. Still choppy. Using the Metal HUD I see FPS capping at 45fps, whereas it was hitting 60fps before. Also the GPU + fans clearly do not hit the max speed.

The reply to my bug report stated that they are aware of issues and asked for information.

It may be worthwhile to also file a bug to give them a wider net in order to solve.

I already filed a bug report yesterday and got a similar response. They are fast .

Hi, the performance in Mac is just not good, here my analysis using other ways to play and the Metal HUD:

It is known that performance on Mac is not on par with Windows, but this thread is about a regression.
I do agree that we should be doing what we can to get better Mac support + improve performance.

Your point about Metal 2.1 in your earlier post is interesting. Though I am skeptical that just the use of 2.1 vs. 3 is responsible for reduced performance on the Mac vs. Windows. There might be some low-hanging fruits/code changes that could help with these issues. Note also that when BG3 development started Metal 3 was probably not out at all...

Just my 2 cents: I experience the 'slowness' on act 1 (still). So it's not related to act 3 or some such. Seems to be something general. I'm on macOS 14.7.

Indeed, I am also pretty sure that this is a generic issue. Act 3 was fine (once the fans hit max) before patch 7 (hotfix 27).

I kinda assumed that it wasn't just Act 3. It just happened to be where my current game was and I wanted to be specific.

I did turn a couple settings down from Ultra to high (all things that were fine the day before), but no change. Since this is my... 4th?... playthrough, I am just going to wait for a fix rather than mess with settings more.

Does anyone else have crashing issues in act 3? Every time I start a conversation my game freezes.
