Administrator Popular Post JuanP Posted August 14, 2020 Administrator Popular Post Share Posted August 14, 2020 A software that can keep up with you! Vectorworks 2021 brings you performance enhancements with better response times in 3D navigation and file load times up to five times faster. Additional caching unlocks the full potential of your hardware, shortening wait times and eliminating redundancies by making more operations multi-threaded. This way you can focus on what’s important: your design. Tell us what you think below! 19 Quote Link to comment
Kevin McAllister Posted August 18, 2020 Share Posted August 18, 2020 @JuanP do you happen to know why these teaser posts don't show up in my unread forum posts? Are they originally hidden posts that you reveal? I'm not sure that many forum users are seeing them....... Kevin 1 Quote Link to comment
Administrator JuanP Posted August 18, 2020 Author Administrator Share Posted August 18, 2020 @Kevin McAllister You're correct they are originally hidden post, I will check the forum settings to see if there is anything else I can do. If not, I will start posting the same day. Thanks for reporting the issue. 3 Quote Link to comment
_James Posted August 18, 2020 Share Posted August 18, 2020 @JuanP What is the total number of cores VW2021 will be able to utilise? Am I right in thinking up until now VW's limit was 4 cores? Quote Link to comment
Vectorworks, Inc Employee Popular Post Josh Loy Posted August 18, 2020 Vectorworks, Inc Employee Popular Post Share Posted August 18, 2020 @_James Vectorworks had a core limit in the past which would throttle down tessellation to only use 3 cores; with Vectorworks 2021 it will use the available number of cores in your system. 11 Quote Link to comment
_James Posted August 18, 2020 Share Posted August 18, 2020 @Josh Loy Cool! So theoretically if you had a fancy AMD processor with 64 cores and you had a theoretical process that could be parallelised across these cores (not including renderworks as I think that could already use any number of cores) there is nothing in VW stopping this from happening? It sounds great and hopefully results in a big improvement. 1 Quote Link to comment
Mark Aceto Posted August 18, 2020 Share Posted August 18, 2020 (edited) This feels too good to be true... what’s the catch? Edited August 18, 2020 by Mark Aceto 2 Quote Link to comment
Samuel Derenboim Posted August 18, 2020 Share Posted August 18, 2020 @Josh Loy Does this include hidden line processing / rendering in viewports? I know that it wasn't supported for multi threaded computation. Has that changed? 2 Quote Link to comment
Vectorworks, Inc Employee Popular Post Josh Loy Posted August 18, 2020 Vectorworks, Inc Employee Popular Post Share Posted August 18, 2020 @_James Renderworks has and will continue to use all available cores while rendering but I believe it is capped at 16. @Mark Aceto there is a little catch to file size because we needed to save some additional data to help with the threads efficiency. Our primary focus for VW2021 was improving the performance getting graphics data to the renderers and have seen great speedups switching layers and visibilities when in 3D views. All of this said we're always working to improve performance and have more gains to come in future versions. @Samuel Derenboim no improvements with hidden line this release but I wouldn't be surprised if it was next on the list. 5 Quote Link to comment
Mark Aceto Posted August 18, 2020 Share Posted August 18, 2020 (edited) @Josh Loy thanks for clarifying. Improvements to Hidden Line are always welcome! Does this caching increase file size? Edited August 18, 2020 by Mark Aceto Quote Link to comment

For example, the Ryzen 3960 looks like the best performance (and value) in the table below. @Josh Loy what are you thoughts? Also, how will the GPU/VGM factor into this?

Vectorworks, Inc Employee Josh Loy Posted August 18, 2020 Vectorworks, Inc Employee Share Posted August 18, 2020 2 hours ago, Mark Aceto said: So, without being able to test drive this yet, this really doesn’t sound like true multicore performance in the sense that we’ve all been hoping for (as it was announced 2 years ago in a Teaser Tuesday). This sounds more like a workaround to speed up viewing vs drafting/modeling/rendering (at the expense of file size which could be an issue when project sharing). Hey @Mark Aceto thanks for the feedback, I not exactly sure where you're going with this but any speedup for drafting/modeling/rendering seems like a win to me. This system is independent of Project Sharing and will have no impact on its performance. 1 hour ago, Mark Aceto said: This announcement reminds of last year when instead of moving more processes from the CPU to the GPU (VGM) as was the trend from 2015-2018, the workaround was to draw less detail in the background. Reading between the lines, it sounds like GPU and multicore optimization have plateaued, and we should manage our expectations accordingly. I wouldn't say anything has plateaued or that there are any lines to read between. We support a vast set of hardware and must provide support for a broad range of workflows while always providing the best experience. The more tasks we can multi-thread and multi-task the better. 1 hour ago, Mark Aceto said: I spend 80% of my time drafting and modeling (not just opening files and viewing the model). I spend 20% of my time plating (wireframe, hidden line, OpenGL). And I'm on a Mac, so I need the fastest single core base clock speed available. Awesome and I'm sure most users fall into this same category, the performance gains will absolutely help your large model workflows while working in wireframe and OpenGL. I would also agree and recommend higher clock speeds over core counts as long as you have at least 6 cores; I'm also on the Mac. 1 hour ago, Mark Aceto said: Sounds like VW2021 will make use of more storage and faster broadband (to save and share larger file sizes). That said, I automatically uncheck all caching options to minimize file size, so I'll be passing on this feature. It will use more storage 10 to 30% that I've seen up to this point, and if that's an issue for your broadband it can be easily disable just like "Viewport cache." I wouldn't make any choices or pass judgement until you try it and are happily surprised. 🙂 1 hour ago, Mark Aceto said: Considering that adding cores lowers clock speed, and potentially increases thermals (if VW is actually using more than 1-3 cores), I would still go for the fastest CPU base clock speed. Some of this logic isn't quite correct. As clock speed increases the power demand isn't linear, meaning the same 'n' amount of work can be done on 4 cores at lower clock speeds in the same amount of time and using less power than a high clocked processor. Base clock speeds are pretty useless as the system will ramp up and down the clock speed depending on demand. You'd probably be better served looking at the single and multi-core turbo speeds since they're generally the limiting factor and usually not far apart. If you want to get really into it TDP will generally dictate the performance you'll see since cores can run at different speeds and in the end heat limits it all. Feel free to direct message me if you want to talk about this more or have any additional questions. 1 Quote Link to comment

Feel free to direct message me if you want to talk about this more or have any additional questions. Thanks, Josh. After rewatching the videos from 2 years ago, I deleted/edited a lot of my initial responses but thanks for taking the time to reply. As for clock speed, the Turbo Boost speeds have proven to be little more than marketing BS for us Mac users, so the real world turbo usually splits the difference between the base clock and the turbo boost (until it gets too hot). The other point of reference is when my Mac maxes out with the message "Vectorworks 20XX (Not Responding)" and I look at Activity Monitor, and see 1 thread slammed against the ceiling, and all the other threads not even being used. That's why the CPU-constraint has always been the speed of a single core/thread. I don't care about the other 19 threads that aren't even being used if they're dragging down the performance of the one that is being used. The 2nd screenshot shows the "4.5GHz" turbo boost maxing out at 4.26 which is the fastest I ever saw it spike on that 2017 iMac Pro. Edited August 18, 2020 by Mark Aceto 1 Quote Link to comment
Mark Aceto Posted August 18, 2020 Share Posted August 18, 2020 (edited) And then there's Cinema/RW efficiently using all 20 threads @ 3.68GHz... This is the dream (even just 4 cores/8 threads instead of 1 thread would be an 800% improvement): Edited August 18, 2020 by Mark Aceto 1 Quote Link to comment

line-weight Posted August 19, 2020 Share Posted August 19, 2020 It's a little disappointing to hear that there will be no improvements to hidden line rendering. I find 3d performance not bad as it is. I can spin around my 3d models pretty smoothly most of the time. Most of my time spent waiting for VW to draw something, is spent waiting for it to draw hidden line viewports. 3 Quote Link to comment

Tobias Kern Posted August 19, 2020 Share Posted August 19, 2020 Hi, this looks promising. Enhancements are always very welcome! Biplap mentioned in the last Design Summit 2020 that, for us Macusers Vectorworks 2021 supports Apple Metal. See this: https://www.vectorworks.net/design-summit/virtual-keynote?utm_campaign=blog&utm_medium=planetvectorworks&utm_source=button&utm_content=042320summitkeynote&hsCtaTracking=fef62d7d-b19b-4108-bc45-de2b801c36c7%7C2fa30288-08a8-44a9-aced-94cdd10b05e1 Does the Performance Enhancements only enhances the CPU, or does it also affect the GPU (with Apple Metal)? … or ist the Apple Metal Enhancement a separate thing? Greetings from Germany Toby 1 Quote Link to comment
Guest SteveJ Posted August 19, 2020 Share Posted August 19, 2020 Hello Toby. Apple Metal is a separate thing. These 2021 enhancements target the CPU. We are committed to providing a smooth transition to Apple’s Metal. In 2021 our focus is to maintain quality and stability as Apple transitions to its new Big Sur Mac OS 11. That said, please know that we are hard at work transitioning our VGM to use Metal and we plan to replace all OpenGL with Metal for the 2022 release. Speaking of Big Sur... It is very nice to report that we have been working with Apple and their Big Sur beta since its introduction in late June - ALL known issues have been resolved. We will be providing more updates about Big Sur compatibility in the near future. Quote Link to comment
