I've been at this for the last 4 days - all day, every day.
I searched the trenches of the internets (and came back, hollowed eyed) in order to find a solution, but to no avail
The thing is that I recently bought a new pc workstation w/ the following specs:
32 Bg Gigabyte Motherboard - Intel i7 hexacore 4930K 3,4GHz w/ hyperthr. (12Mb Cache)
2 x Kingston HyperX 3K SSD 120GB - raid for OS and apps
1 x Kingston HyperX 3K SSD 120GB - as AE's dedicated Scratch disk
1 x Western Digital WD20EZRX 2 TB - as storage
Windows 8 / AE CS6 184.108.40.206
- Adaptive Resolution Limit: 1/8 (Ray-tracing on CPU since my GTX-780 isn't in the list)
Viewer Quality: Zoom Quality: Faster
Color Mgmt Quality: More Accurate Except RAM Preview
Alternate RAM Preview: Preview: 5 frames
Media & Disk Cache:
- Disk Cache enabled (max. Disk Cache Size: 100 Gb) - set on AE's dedicated Scratch disk
- Conformed Media Cache: Database & Cache - also set on AE's dedicated Scratch disk
Memory & Multiprocessing
- Installed RAM: 31,0 Gb
- RAM reserved for other applications: 15Gb (I'm also using Maxon C4d)
- After Effects Multiprocessing's Render Multiple Frames Simulteneously: enabled
- Installed CPU's: 12
- CPUs reserved for other apps: 6
- RAM allocation per background CPU: 3 Gb
- Actual CPUs that will be used: 4
My problem now is that my RAM previews (w/ and w/o Shift) are pretty darn slow, regarding the fact that I'm working on a really basic scene now in 3D space (Classic Render), involving 1 layer w/ the Stroke effect, VCP's Sure Target 2 cam set up and 2 small precomps w/ a small folding contentframe.
To RAM preview a 5 sec take, it takes almost 10 sec to build up this little scene. When I look at the processes in my task manager, I see that as soon as I RAM preview to my Scratch disk, the writing speed is a very dissapointing 3,4 Mb/s. I take it that this is an AE issue, since writingspeed to my Scratch SSD is checked and confirmed 180Gb/s +.
Does anyone here perhaps has a pointer in the right direction? I want to sleep again
Many thanks in advance, appreciate the help!
Expression evaluation is single-threaded and that's exactly what happens when you use Sure Target.
Thanks Mr. Mylenium,
I kind of was expecting that ST could be (one of) the culprits, so I'll have a look at alternative cam rigs.
But, also w/o ST, but only w/ the Stroke effect applied, I have that slow RAM performance (and SSD writing speed). Could that effect also be suspect?
And, furthermore: could you be so kind and feedback me on my AE preference setup? Is that as it should be?
Again, many thanks in advance.
