Infoseite // After Effects CS3 and multicore frighteningly ineffective?

Frage von Trigget:


Good morning, thanks to some problems I thought I you ask me, on my current system:

Win XP 64bit (5.2, Build 3790)
2x Quad Xeon 2.66 GHz
Quadro FX 5600
8 GB Ram
Raid 10

After Effects is running in the pleasant Peview liquid, but the rendering takes place on 2 of the 8 cores with a capacity of just 12% instead of max, memory capacity of garnicht first to talk (thanks to 32bit).

Preferences:
Maximum memory using 120% = 4 GB
Maximum RAM cache 90%
Maximum Disk Cache: 8000 MB
More process processing course
OpenGL rendering to

Win Pageing file (on disk C and D)
Initial: 4000 MB
Max 8000 MB

The performance of this system is currently about 20% over a single core 32bit system 2.4 AMD ancient synonymous here I still have lying around the kitchen. After seeing the same Xeon machine here again and will have this with a 32bit Win up've seen the performance of different values is not large, but this is only a nuclear capacity. If the multi-CPU capability of AE really Miess or so I have something fundamental overlooked?

Hi,
may be that this is again one of the imponderables of the Open GL option.
You might want to have this script at times.

This allows you to render explicitly to adapt the existing cores.
That you are in the default memory settings mentioned in connection with multi-core CPUs have used I assume.

Your graphics card has multiple cores? Hardly. Off for final renderings.

Complete nonsense for multiprocessing. To give you the foreground process so virtually half of your system memory and the background processes can not breathe. Both around 30% funzt much better.

Antwort von Trigget:

Thank you, both seemed to work wonders and it is nice but then this machine will eventually but with a significant advantage to be seen. Now I still have the problem solved the AF only my 4 GB RAM 8 GB recognizes. Believers but the times have somewhere found a solution to have.

Once you a warm thank you gave me my faith back where s.meine workstation.

I think not. To my knowledge, are not optimized for 64bit applications max.4 G RAM per app assignable.
For an 8 core for AE, it is probably cheaper then only 4 cores attributable
and show where each 1G RAM spendier.
Very detailed instructions on this subject are Adobe

Read through your times. "Render multiple frames simultaneously" is exactly what you are looking for.

Does not. AE is a 32bit application and 2 ^ 32 times now just 4 GB and so Klecker bytes.

Yeah, I just tried and am in the same project with 4 scores 25% slower than with all 8 cores without BG Renderer. With new knowledge, I like to post more details as I now synonymous times will look like the whole as opposed to 32bit system proposes.
