Can anyone say when the metal improvements are slated to be released? Will 3.2 or 3.3 include metal performance improvements or are they later than this? I don’t recall seeing it mentioned in the 3.2 notes.
We’re Apple fans at work but we’re about to change to PC workstations because of our view port and render time perf just not being where the team need it, which is sad but I’d like to see if this is about to change. A 2x improvement would fix this for now
Thanks
As such, it’s possible this patch could be implemented soon. However, based on these rendering meeting notes (link) it seems like some adjustments are expected to be made before the feature gets merged into Cycles. And I don’t know how long it will take to make those changes and so I can’t tell you when this patch will be accepted and merged with Blender.
I’m not completely sure about this but I believe that the 1.1x improvement already landed. Previously around 03:11 in Classroom on my M1 Pro. Now in 3.3 alpha it’s 02:53. Very small change but I think it’s worth mentioning.
Hey, on relatively simple scenes cycles on metal has been performing pretty great. but when I start using on some more complex shots with linked libraries with overrides, view layers, and AOVs, I frequently run into issues where things suddenly will stop rendering or the entire system will lock up. the console reports a variety of issues, some of which specifically mention cycles metal (attached screenshots).
its hard to troubleshoot what is causing it, since it can render find one moment, and then the next it fails. and then render fine after a restart.
Hi all,
On the BMW test, I got 1:24 on Blender 3.3 (May 17 build) and 1:18 on Blender 3.1 (Stable).
Perhaps this is just for this test? I will update this post with some more scenes later when I get the chance. Just wanted to let you all know that the time went down.
Not sure if I’m doing something wrong but on M1Max 64GB running Monterey 12.4 just got 102s on the Classroom and 49s on the BMW scene. Both on the 3.3 Apple Silicon build (GPU only compute)!
Good tip, but I tried it and I notice no difference between scaled or screen default, which is “looks like 1080” I think maybe the effort of scaling the screen is marginal compared to the actual 3d content. Mac Studio Ultra.
