optimizing 8 core 8gb ram for AE CS3
greetings from seattle
just updated 8.0.1.8 after having issues with ram previewing.
in my activity monitor, i still dont feel like im getting the full benefit of the 8-cores and all my memory.
any white papers on optimizing this.
i also have a Radeon x1900 that came with the machine. I still feel like i havent tasted open GL yet. its always something that i turn off when machines act buggy and usually it helps. is this a decent graphics card and should i be expecting to get any use out of open GL?
thanks

i have half your system (4-core, 4gb ram)…
i’ve done some testing of various settings used the benchmarks i found at barefeats.com as a reference. i used the same total benchmark project files that they used (barefeats has a link to them).
i found that after enabling multiprocessing (which provided a noticeable difference), i had no change in performance by altering my ram cache to allow all processors to be used (with default settings and 4gb of ram ae only used 3 cores). so i left it with the default memory settings and figured i’d have one core to use for surfing the cow.
i also found that setting previews to always use opengl, multiprocessing was disabled for previews (which make sense when you think about it).
so my suggestion would be to download the total benchmark project, use the barefeats graphs as a reference point and tweak some settings to see how yours compares.

already testing with it. im not quite as fast as the 16gb ram machione they used at barefeats, but not far off. disabling multi-proc is over 2x slower.
ram previews are still wierd on this thing, i want this thing be as good interactively /ui response-wise as it is a straight renderer. just put the extra ram in, so hopefully it will crank.
the activity monitor still shows half the CPU not working on MP enables renders…
does this weather suck or what
i used to ride my bike down dexter everyday for 3 years, now i work by victory studios, have to drive -
yup, the weather stinks… sounds like the weekend may get better though. i live down south (can’t afford a family and a home in the city) and my commute has gotten worse just due to the weather…
as far as ram previews, i’ve noticed that they occationally hang at first (and not just the first time the render engines get loaded). also, they sort of surge.. like it renders 3 frames, then pause, then 3 frames, then pause… i assume that’s just my 3 cores rendering, then waiting for the next 3 rendered frames….
but other than that, it has worked pretty consistently.

so is there a ‘final word’ on cache-setup
i totally notice the surging.
is nucleo way faster? i recommended to Rob-art from barefeats to compare AE with and without nucleo 2… would be interesting… this machine is still fast, but unreliable and unhappy previews are killing me

eh! i am starting to grow unfond of AEcS3.
We have an octo-core mac pro w/32 monstrous gigs of ram. It takes AE FOREVER TO GET ROLLING with a render. (you know…the line that says allocating resources…this may take some time…) It has to allocate all of its resources. However Nucleo allocates its resources before it renders, and freezes substantially less than AE. Nucleo isn’t faster, its just more efficient and more consistent. When doing some tests, the AE engine barely used any of our Ram and did not spike the cores in the Activity monitor, and other times it did. Nucleo did it consistently every time.
Think about it. Nucleo’s been around for how long? 2 or 3 years? Ae’s multicore functionality has been around for what? 6 months? I think nucleo’s a worthwhile investment. AE is rocky now, but in a few updates it might be stable.

another thing on the horizon is osx leopard…. supposedly, it will improve ram management for multi-core macs, which is evidently a big problem right now with efficiently feeding multiple processors enough data to perform as well as they could…. but i guess we’ll start to see how much it can help next week.

exactly… as a pure renderer, pretty fast – as the response we would expect from this kind of horse power, not there. render speeds are important no doubt, but i just want fast interaction.
i feel like the ui is zippier with MP turned off.

with the 8.0.1.8 update, (if you haven’t already) you can enable the hardware accelerated panels in ae’s display preference… it may help your ui issue.

I have to say OSX leopard and a mac is starting to look like a much more attractive prospect than trying to botch one of Microsoft’s OS’s to work properly with pro apps and still have drivers for everything else. Especially with OSX running Windows aswell if needs be..
Seems there is no version of Windows that is upto scratch at the mo..take note MS.
