Sad to report I'm running multi machines editing on OSX 10.13.6 Macpro 12 cores 16 gigs to 32 gigs of ram on a Nexis 100TB. After working for a couple of hours avid begins to get sluggish with poor performance. I can report that this has happened on 4 machines that I've upgraded from 2018.12.1 to  2018.12.2

side note: let's hope the next version is 2019.4? it's a new year!

Hi t3chfaith,

  I send this over to support team 03678983.

Thanks,

I'm having a similar experience here.

Tom

Yes! It starts working fine then slows down to the point you can't work. A reboot fixes it but then it just goes right back to slowing down again after an hour of working.

I'll be honest here I have no idea how this was released without real-world testing in a post-production environment. I've been catching so many errors and issue's with these new avids being released, I have multi-tickets opened.

Resolved in 2018.12.3 coming soon.

Hi Marianna,

I have 2018.12.3 and I'm still having the same sluggishness after a few hours. Makes MC unusable until you restart computer.

I'm working on MC 2018.12.5 for the first time on my home MacPro mid 2012 12Core 2.66 GHz, Mac OS 10.12.6, GTX-680 2GB vram, 64GB ram.  I'm on a 4K 4096_2160 Rec 709 project.  I rendered a safe color limit on upper track to ProResHQ, like I always do and am getting stuttery playback in 10 bit green.  Usually this plays smoothly but I just jumped from MC 2018.12.1.  At work I have a similar setup but with a mid 2010 MacPro and there I have a sanmp fibre raid chassis and this works.  At home I'm playing off an internal 4 drive apple software raid with 4 x 4TB Hitachi Deskstar drives.  I know this has worked in the past with even a 3 drive stripe.  I've experienced more strained performance on the later MC 2018 software, I know it's not qualified but it's worked so far

I had heard of the memory leak but what I found today when I discovered the stuttery play I quit MC and looked at activity monitor memory tab and even with Avid quit the memory tab show Avid Link using over 18GB or ram.  I restarted the computer and checked activity monitor and Avid link was around 300mB.  I quit Avid Link and launched Avid and now it plays without stutter, at least for now.  Before when I had the stutter Avid had been running all afternoon and rendering for 3.5 hours.  I don't understand why Avid link would ever use 18GB or ram, especially after quitting Avid.

Does Activity Monitor not reflect the current usage of memory of an app/software?  When I saw 18GB or memory for Avid link did that actually mean that at that moment Avid link was using 18GB.  I don't know if this is also a memory leak issue.  I recall that when I questioned how much cpu etc... Avid link was taking I was told a new version was coming out to address that in some way.

So is the Avid link usage I'm seeing indicate a real problem of system resources?  Don't know if it's tied to my stuttery playback or what.

I just had the stutter come back.  I found if I went to 8bit green no stutter.  Perhaps there is something about ProResHQ render at play here.  I'm going to rerender to DNxHRHQX to see if I get better performance.  Possibllly the VBR of ProResHQ might be at play here?  Just guessing out loud.
