A couple of small updates: I rendered the candle stand on my old 2018 i9 (Intel) MacBook Pro. I didn’t write down the time, but it was about a minute. So the M1 Max is about twice as fast. This is single core performance on both machines and running the script without any modifications. Performing the same test under virtualized Ubuntu using OpenSCAD 2021.01, I get 12 seconds again. There is no discernible time difference between the 2019.05 and 2021.01 releases of OpenSCAD. Even virtualized, the linux version is faster. I don’t have any explanation for it. If anyone wants to try out a native M1 version, I can make the thing I compiled available somehow. Compiling it yourself is pretty easy if you use HomeBrew. Of all the open source stuff I’m trying to compile for Apple Silicon, OpenSCAD has been the easiest. Compiling everything from source is more tricky, but those problems are solvable. > On Nov 14, 2021, at 2:36 PM, David Schooley <dcschooley@gmail.com> wrote: > > Yes. All three on the MBP M1 Max.

My Dec 20 16gb M1 Mac Mini previews the candle example in 0.049secs and renders it in 30.862 secs When I first got the M1 I was impressed with the render times compared to my old 2012 I& MacBook, but with my non-optimised designs for some reason it could be a lot slower in the preview. NOP_HEAD provided me with some hints in a thread back earlier in the year. cheers BobC in the UK On 15 Nov 2021, at 20:54, Bob Carlson <bob@rjcarlson.com> wrote: > > I probably will get the new mini when it gets the new chips no matter what.

FWIW, I just tested that one on my M1 Max, I got .055 seconds to preview and 17.502 seconds to render. This is using a recent nightly with all of the experimental optimizations turned on.

I still think that’s too slow given that the linux version does it in 12 seconds out of the box. > On Nov 16, 2021, at 2:48 PM, Whosawhatsis <whosawhatsis@gmail.com> wrote: > > FWIW, I just tested that one on my M1 Max, I got .055 seconds to preview and 17.502 seconds to render.
