Advice Photoshop .psb large format images

<p>Hello guys,<br>

I created the 160.000 X 300.000 pixels image. <br>

<br />When saved on Hard Disk the file size is 4.7 GB, but while working on photoshop it says 110/120 GB.<br /><br />Problem 1) With my current laptop it takes more than 20 hours to save it. (I saved it with compression thou)<br /><br />Problem 2) The image also contains a lot of layers, and when I start to work on the file, like adding objects and moving layers (please consider I'm not using filters, i'm simply creating a kind of mosaic), at the begininng Photoshop responds fast. But more things I do, more time it takes to esecute the command. After 20/30 minutes it becomes very slow, taking up to 2/3 minutes to move a layer or to add a new object... And the time keep increasing up to 5 minutes... (I tried also to remove "undo actions" but improvement is marginal)<br /><br />Problem 3) I stopped to work on it as was strenuos and as I decided I need a new desktop for this project. But when I will resume my work, i estimateed the images size may increase over 10 Gb.<br /><br /><strong>This is my current Laptop: DELL INSPIRION 15-3521 (Pentium 2127U 1.9 GHz / RAM 4GB / HD 500GB / Win 8.1 64 bit)</strong><br /><br />So this is the new desktop configuration i would like to check with you:<br /><br />CPU: i7-6850K 3,6 GHz<br />RAM: G.Skill Ripjaws DDR4 64GB (4x16GB) 3.000<br />GPU: Sapphire AMD RX 480 8GB<br />STORAGE: Samsung 960 EVO NVMe SSD 500 GB<br />STORAGE: WD Black 3.5 7.200RMP 2TB<br /><br /><br />According to your experience do you think will it be enough to work on my project?<br /><br />Do you have any suggestions to change some of the components?<br>

<br /><strong>Please consider my goal is to reduce drastically the saving time and being able to work on the image without minutes idle time beetween commands.</strong><br>

<br />(If printed the image will be big as much as a soccer field. But I don't have to print it.<br />When I will have finished to work on it, I will use krpano software to tile the image and making it viewable/zommable like google map)<br>

<br />Thanks a lot,<br />Ciao<br />Kel</p>

<p>Heavy Photoshop on a machine with 4GB RAM is why you are having such a hard time. The maximum RAM on your current laptop is 16GB, upgrading to that might help. So would switching to a solid-state disk drive.<br>

But your file is so insanely big that 16GB probably isn't enough either. You really need a lot of RAM, that may demand a desktop system. At 64GB RAM (which you propose), Photoshop would still be paging the image out to disk. You probably want to think about 256GB of RAM, which is going to be <em>expensive</em>.<br>

Also, compressing when saving is also non-beneficial in this situation. That's incredibly compute intensive. That's why it takes so long. But you may need a much larger disk to work with non-compressed files.</p>

<p> </p>

<p>1. switch to a 64 bit machine and 64 bit version of PS if you are on a 32 bit version.<br>

2. maximize your ram whether on a lap top or desktop.<br>

3. add a second hard drive and set it to be the scratch disk. default is the c drive, same as the OS and programs.<br>

4. set PS catch levels to 8, the maximum.<br>

5. set PS to use 80% to 90% of available ram, this will depend on your computer and how much the OS needs to operate.<br>

PS Edit Preferences Performance for 3, 4, 5.<br>

I'm on a Dell XPS 8500 running a clean install of Windows 10 64 bit, 3.4ghz i7, 16 gb ram. I rarely open any file larger than .5bg and never have a lot of layers.</p>

<p>Dell packs a lot of background apps that run when you are editing as they think the computer is idle. You can find the windows serial number for your computer and it will work with a clean install of windows. you will loose things like pc doctor and dell detect. an alternative is to disable your internet connection while editing to prevent background apps from accessing the internet and slowing the computer down. I sometimes have to turn my security suite OFF as it starts running in the background loading the computer down.</p>

PhotoShop in general is very hungry of memory,

and doesn't release it until shut down and re-

started. The longer you continuously use PS, the

less free memory you'll have, and the slower it'll

get. Try another program if all you need to do is

mosaic image tiles together.

Graphic processor speed is fairly irrelevant with simple 2D images. Texture rendering etc is almost non existent. However, the amount of graphics RAM and its speed is important. Get a graphics card with stacks of GRAM and forget about its GPU speed.
