I was unable to replicate the iMac Pro-specific crashing as of their first 10.13.5 beta and the rest of the betas seemed to continue the trend. We found that the issue was driver related, so on the Mac side that means a OS update to fix. 1 Quote Link to comment
zoomer Posted June 1, 2018 Share Posted June 1, 2018 ^Thanks ! So I don't need to fear any new issues with VW and my outdated nMac Pro w/o the "i" too. Quote Link to comment
markymarc Posted June 1, 2018 Share Posted June 1, 2018 Thanks @Hans-Olav . The 3.2 Ghz you bought, that's the 8 core I assume? Quote Link to comment
markymarc Posted June 1, 2018 Share Posted June 1, 2018 Thanks @zoomer for the excellent thoguths and explanations. Seems to all make sense. What I dont' understand is the 'turbo-speed' vs the quote speed (4.5 Ghz vs 3 in the 10 core, or 4.2 vs 3.2 in the 8 core). What does the turbo mean, and which one is more relevant?

markymarc Posted June 1, 2018 Share Posted June 1, 2018 Thanks @JimW . I do use Renderworks, but probably mostly to present shadow studies, or in elevations etc as a white card model with hidden line rendering over the front of it, or something along those lines. These viewports usually take 1-2 minutes to render - so do you reckon that time could be increase by 10 vs 8 core, or is it too marginal to be relevant? Thanks for all your help everyone , I'll let you know how I go with what I get in the end 🙂 Quote Link to comment
zoomer Posted June 1, 2018 Share Posted June 1, 2018 (edited) The normal core speed is when all cores are working. As not all work is multithreaded often some cores are not in use. In this case a single (or a few) cores can run at even higher clock speeds. Without exceeding specced temperature or power consumption. That is the maximum Turbo Boost speed. This is normally for a single core only while others are sleeping (nowadays sometimes even 2 cores) If more cores are active that speed is reduced step by step. like you can see here in the tables : https://marco.org/2013/11/26/new-mac-pro-cpus Edited June 1, 2018 by zoomer 1 Quote Link to comment

Andrew Pollock Posted June 2, 2018 Share Posted June 2, 2018 I just upgraded to 10.13.5 and I can no longer make VW2018 crash on my iMac Pro when using walkthrough or flyover in open GL. Until the upgrade, it was crashing often. very happy, now back to work. 2 Quote Link to comment
Andrew Pollock Posted June 2, 2018 Share Posted June 2, 2018 I will add my two cents about my iMac Pro (8 core, Radeon Pro Vega 64) experience. I mostly do 3d design work and walk throughs in open GL. The video card makes open GL work much smoother and now that its not crashing anymore (hopefully) I'm very happy with the machine. Simple 2d work is only bit faster then my old 2012 27" iMac, but when my 2D work has many bitmaps there is a great improvement in speed. Since I keep multiple programs open, some running in the background while I work on VW, I believe the extra cores are helpful. If I'm creating an animation, I can jump to Mall or Word and I'm not aware at all the a rendering process is going on in the background. This was not the case in my old machine. If one wanted to optimize the VW experience on an iMac Pro, the 10 core machine has the highest single core speed. If you are doing a lot of long Renderworks rendreings or cinema 4d work, Mac my not be your best bet. 2 Quote Link to comment

Too marginal in that case I would say. 1 Quote Link to comment

Now I feel like I should go back and check what the exact specs were that I've been working with to date, so I can better compare 🙂 Cheers 1 Quote Link to comment

In this quick test render for another video I'm currently recording about Lit Fog: My Macbook Pro took 9 minutes 58 seconds. The iMac Pro took 2 minutes 38 seconds. Has any one run this Stained glass test on a new 2018 MacBook Pro? How long does it take for a preview to check lighting? I never sit and watch my Mac while rendering. Walk away time. However the killer for me is setting lights and waiting for previews. That is a time killer. Quote Link to comment
