I've got a bit of an issue. Whenever I go for a RAM preview, after effects decides to stop and have a think for a few minutes. This happens even on low-res footage and without any audio.
I'm also a bit disappointed with the general speed I'm getting in After Effects, but fear it is something simple I'm doing in my memory settings.
Please take a look below at my AE preferences and System info. Many thanks for any help. (There isn't much else running on my computer)
I should add that I'm running CS5
Disable multiprocessing. Pointless exercise to even try with only 4GB of RAM....
