I seem to be having an issue with the image cache not updating quickly.
For example, I will scroll around my timeline or turn on and off layers and will not see a change in my composition window until 10 seconds later or it wont update at all. I find myself continually going to edit > purge > purge all memory & disk cache.
Im working on a laptop, osx 10.12.5, 2.5ghz intel core i7, 16gb memory, graphics: intel iris pro 1536mb. There is about 200gb of space left on my 500gb flash storage drive.
I tried using an external ssd (usb3.0) to see if that would help but still slow. I thought it might be my laptop but im also having the same trouble at home on my iMac, which is more powerful.
One thing I do notice is that if I put the "posterize time" effect on a comp, that will slow it down even more.
Im kind of at a loss of what to do. I just started having this problem about a month ago or so. Any help is much appreciated!
