Try updating to version 14.2
With the new 2017.2 it's getting worse...
I can not do any preview....
Are there some helpful tipps?
purged all, restarted, put it in a new comp, tried different renderers.
when i move the CTI (with cursor or mouse), the green ram-bar is just on the current time.
previous green-ram disappears.....
no ram problems with other (also adobe) programs
disk-cache isn't on the system drive.
OS X 10.11.6
AE 2017.2 (22.214.171.124)
Mac Pro (Mid 2010)
2 x 2,93 GHz 6-Core Intel Xeon
12 GB 1333 MHz DDR3 ECC
NVIDIA Quadro K5000 4096 MB
I updated OS X, after the restart graphicscard said that there are no drivers available for the current OS, but after some seconds the graphicsdriver updater told me there is a new driver abailable. After that..... TATAAAAAAA......
until now everything works fine!
