I adopted Sharp3d perhaps 2 years ago, downloaded it on holiday in Lanzerote (as it happens) to keep the mind busy. HAven’t looked back since.
That was on the iPad Air 4th Generation 11”. I also have in on an iMac, but it’s on the iPad that it shines for me.
Last week upgraded to the iPad Pro 13” M5. Man it is sweeeeeet! Highly recommend!
I’m on a new M5 MacBook Air and Shapr3D was super performant in the beginning, but at least with the model I’m working on, it has slowed to virtually unusable levels when creating sketches (spinning and viewing the model is still very smooth). I describe my issue here: https://discourse.shapr3d.com/t/max-features-in-history/41160
I don’t know whether this issue is project-specific, if Shapr3D generally struggles with larger history models, or if this is a Mac-specific issue. I need to try testing on a Windows PC to see if things are any better.
The M5 is suppose to eat this stuff up. Low power mode?
Shapr3D couldn’t render the rat rig vcore 4 on my iPad Air. But did on my iMac i5. Haven’t tried it on the M5 iPad yet. Happy to see how it performs on this iPad M5 if you want to send me the file.
Mostly on my PC, but also on the ipad pro M4, especially when the weather is nice outside. 
Also have it installed on my Macbook Air M1, but I’d say that’s for rather light work only.
Home built Ryzen 7 PC running with a very lean and tuned install Win 11.
Nice how does it perform?
My son has an i9 with 5080 RTX I ought to try in on there to compare.
I’m still running a 2080 Ti. Honestly, no complaints on that front, it’s not that far behind current GPUs when no fancy stuff like raytracing is needed.
I think my i9-9900K is more of a bottleneck. 
Pretty rock solid. I would add more RAM but DDR5 is a million bucks a byte these days.
Good card 2080 Ti. I have a 2080 super ventus in the garage pc. It works great and will run Unreal Engine ok.
3080 OC in the daughter’s machine which is a really really good card for its age.
AMD Ryzen 7 7800X3D 8-Core is a pretty good bang for the buck processor.
AMD Radeon RX 9060 XT is my first ever Radeon. I am uneasy about it not being an Nvidia card. Readon doesn’t have regular driver updates and that makes me nervous. Maybe that’s good?
I am tend to do “most bang for the buck” builds to work and play on.
Shapr3D on my 2024 iPad Pro M4 runs really great for me, noticably faster on large models (with hundreds of parts) than my previous 2021 iPad Pro M1. Working on models with smaller number of parts shows hardly any difference, but the M1 starts to slow down sooner once part numbers go into several hundred.
Interesting. 13” or 11. I just moved up to 13 and i like it much better for Shapr3D work.
Mostly on my M5 MacBook Pro, sometimes on my iPad Pro.
Both iPads are 12.9”
