preliminary stuff first...
- have you made sure the version of AE you are running is current? (in AE go to the Help menu > Updates)
- have you rebooted your machine
in the realm of AE, 4GB of RAM isn't a whole lot. That possibly could be your issue. Have you checked how the system resources are being used? Are they maxed?
Have you turned on Multiprocessing ? If yes, can you turn it off and can you notice any improvement ?
I7 proc are Quad cores with hyper threading, so it's virtually 8 cores. 4gig of Ram is really not enough for 8 proc, even for 4.
AE works best starting at 2gb / proc. With your 4go, i would not use multiprocessing, or use 2 cores only.
Also is Open GL turned on ?
THanks a lot. It looks like you are right. I'm about to buy some 4GB more. in some few days for sure. I turned of Multiprocessing and now things are a lot better! The Open GL was on but it was not working properly, bow is working well.
not perfectly but a lot better now! I'll buy those 4GB.. that should be enough right?
8Gb is good (I have 8gb on my main PC with vista 64, it's really nice).
But remember, when you set up your cores, be sure that each core gets at least 2Gb of ram. So with 8gig, working with 3 or 4 core should be perfect !
(I personnaly work with 3 cores, as i need the last one for my other apps, and allow 7gb to AE)
