Title: Is it time for a computer upgrade?
Post by: wmchauncey on October 08, 2014, 09:06:59 am: I tried out the stacking tool that Adobe finally got working but it runs slow. The stack of 80, 22 MP images done yesterday,
took over an hour, I do not multitask while running PS. I do have the performance almost maxed-out in Preferences.
Am using a HP Pavilion with a intel i7-920 Processor with 23 of RAM and 64 bit Windows 7 OS.

Would appreciate any and all suggestions directed toward increasing performance as much as reasonable, including computer up-grades.

Edit. I'm sorry I read that as stitch. But it clearly says stack. Do you focus stack? Use a better tool. I use Zerene stacker but there are others.

But anyway, open Task Manager and monitor your core performance and memory usage during the process. If RAM usage maxxes out, it means swaps to disk, which slow things down a lot. If all (or almost all) or your cores are not busy, it means the app is not efficient at multitasking.

Post by: wmchauncey on October 11, 2014, 11:09:13 am: I was incorrect...it is 24GB of Ram and it does max out, even after making adjustments in PS CC Preferences.

Another point is, when Canon introduces a high MP FF body, I'm gonna get one. I can only assume that stacking
35MP images will be more memory intensive than the current 22MP images...right?

I have been using Zerene for about 3 weeks on my floral stuff and found that it does do a great job, except...it does introduce unacceptable noise.
Prior to that, PS CC was my weapon of choice, albeit, a lot of artifacts. Then it quit stacking at all.
But PS CC upgraded last week...the stacking works much better than before with virtually no artifacts.
As a side note, I took a stack from PP CC and Zerene and stacked them together...looked good.

Upgrading to a 36MP camera is going to increase the file sizes proportionally from your 22MP camera.
