Guess I'm just talking to myself here, but I may have found part of the issue with high CPU..
As I mentioned in a previous post, I'm using RAID SSD setup, and really shouldn't have had anything loading into ram as I had things configured properly in 2.9 to accomplish this via suggestion from user gmint:
All you need to do is to set the following preferences and you'll get direct from disk every time:
"When imported, a media is stored in memory when its size is less than:" 0 MB
"When opening a new project, maximum preload memory size:" 0 MB
Voila, everything is direct from disk!
In Modul8 v3, there's different options in the Medias tab:
Start releasing medias when Modul8 uses more than % of the full memory:
When opening a new project maximum preload memory size:
I've had the "Start releasing medias when Modul8 uses more than % of the full memory" set to whatever the default was 70% I think?
I've had the "When opening a new project maximum preload memory size" set to 0 MBytes in order to NOT preload media and go direct from disk on my RAID SSD.
When opening this new beta to my default/template set I experienced the same ramping CPU issues I've been reporting, got up to 50% usage across all cores, video was glitchy and not smooth at all.
Since you suggested I was running out of memory by the crash report (even through I have 32gb ram installed and never see usage over 4gb despite Modul8HD being 64bit?) I thought maybe if I lowered the value for percent of full memory used before the media gets released it would bypass any ram / memory issues..
Low and behold setting this value to 1% IMMEDIATELY dropped my CPU usage from 50% across all cores (i7) to 7-10% and video playback became smooth again.
Basically it seems to be releasing every clip from RAM once it's the next one is done playing - all my clips have red dots in the media sets apart from the currently playing clip, and the previous clip.
Anyhow, any ideas about this? Is this the correct configuration in v3 to stream direct from disk? Just a bit confused about why I would have memory errors suddenly, and only with this app. After Effects, Premiere, C4D, Realflow.. anything I can think of that gets used on the same computer has no issues using my full 32gb, or crashing.
