At the suggestion of an Adobe sales person, I upgraded my PShop CS3 to CS4. The sales person told me that CS4 with Vista Ultimate 32 bit would use close to 4 gigs of RAM if it was available. However, on my system with the RAM usage set to 96%, CS4 uses no more RAM than CS3 did... about 1.6 gigs of my 4 gigs.

Should CS4 use full RAM with Vista 32 bit? If not, is there a PC operating system that will allow CS4 to use up to 4 gigs of RAM?

Need help... working on some very large files...

Vista 64 bit should work, I�m dedicating around 8 gigs to PS CS4 on my work computer.

I honestly don�t know what the maximum RAM is today, I�d guess around 16 (which is probably overdoing it). My work one has 12 and it�s just something that the guys at work put together for me so I doubt there�s a single manufacturer. I can try to find out for you next week.

Vista 64 is suprisingly good, I was reluctant to use it cause of the stigma around it but it was the only choice I had. I have�nt had any problems with it and with just a few settings it�s pretty much like xp only better.

Apps in a 32-bit OS can only ever really access around two gigs on a 4 gig system. The top gigabyte is typically unavailable because Windows uses it to shadow your video RAM. The bottom gig is used by the OS and your background processes. That leaves the middle two gigs for apps to work with.

If you're running out of RAM in Win32, your best bet is to move to Win64.

Nag: I believe maximum RAM depends on what version of Vista you have. I think for Vista Ultimate it's 48 gigs.

Vista 64 Enterprise will see 128GB of RAM
Vista 64 Ultimate will see 128GB of RAM
Vista 64 Business will see 128GB of RAM
Vista 64 Home Premium will see 16GB of RAM
Vista 64 Home will see 8GB RAM

as far as desktops go, 24GB is available with the new Intel i7 chipset using the Asus P6T Deluxe V2 motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E16813131365

Eyewoo: I asked the guys and it�s not off the shelf, it�s all pieced together.

mmmm.. 128 gigs of RAM, just imagine the ramdisk you could create out of that.

B0b · Posted: Thu Jun 04, 2009 4:28 am

yeah, the cost tho'!

im pretty tempted by 24gigs and using 8 or so as a RAM Disk for PS Scratch Very Happy

Photoshop needs the same amount of scratch as you have RAM, so if you allocate 8GB of RAM to PS, it needs 8GB or more for scratch.. a rotating platter of silicone is infinitely slower than RAM, so for ultimate performance, you want to use RAM before hitting the platter

btw Eyewoo, before you go and buy a new operation system then I recommend checking out the windows 7 evaluation. I�m running it at home and it�s working perfectly. (supposed to be faster than vista as well). You can use it for free until June or July next year.

mines started giving me jip with the new PS 4 update..

eyewoo · Posted: Mon Jun 08, 2009 6:47 am

Well... my new system is arriving on Wednesday. Dell desk top with 12 gigs, Vista Ultimate, 64 bit.

Not being that technical, I generally do not want to try a new OS until it's been around awhile. That applies to some software, as well. I learned that when I first started using CorelDRAW! about 15 years ago. That's when they were using their customers as beta testers on what was billed as finished products. Smile

Adobe Photoshop is an exception... I generally jump right on their new versions.

Set up the new system - 12 gig with Vista 64 and PShop CS4... using it with my Cintiq... There is a very annoying lag. I seem to recall in an earlier version of Photoshop, there was some setting that could be turned off which increased speed and decreased lag... Sorry I can't be more specific than that. It was several years ago - maybe PShop 7. AT any rate, might there be something similar in CS4 --- Files in the 3 to 4 Gig Ram become very difficult to work with...

You have to turn ON Aero. If I remember correctly then you just right-click on the desktop and go into window color and appearance settings (or something like that). It makes all the windows and UI semi transparent and slick. What it does is it makes the UI and the windows run on the GPU and thus frees up the CPU.

Sounds kinda stupid to have to turn something on that is graphically intense to reduce lag but that�s what happens.

You might notice some annoying circles appearing around the pen when you click. You just have to turn them off in the tablet-pc window in control panel. There are a few annoying options like that but once you get them out of the way everything should be fine.

Thanks Nag... Have that all set up and rebooted, but the problem still exists.

When doing a cross hatch technique, if I get a line started and swish back and forth without lifting the stylus, the line pretty much stays close to the stylus point. However, if I cross hatch by lifting the stylus to draw a series of separate lines, they get way behind and sometimes lose their brush characteristic for several lines - i.e. a thick non-descript line is drawn.

I'm working here with a 3 gig file with 10 gigs assigned to Photoshop.

How important are the hardware components for this problem?

I have:
Intel Core i&-920 processor(8mb L3 Cache, 2.66 GHz)
12 GB Tri-channel DDR3 SDRAM at 1066MHz on 6 DIMMs
ATI Radeon HD 4870 GDDR5 1924MB graphics card

Thanks much for your help!!!

Not sure what it could be, this does not happen at all on smaller files?

One thing I always do is turn off/down the double click distance in the wacom settings, it sometimes creates strange things at the start of strokes.

Do you get the same problem if you turn off the GPU acceleration in the PS settings?

If the Cintiq is causing the lag, go to the Wacom tablet properties and set Tip Double Click Distance to Off.

Also in Photoshop, make sure the Histogram tab is closed. Otherwise you get the histogram update on every stroke, causing a small lag.

Nag... does not happen on smaller files

Mikko... did it, but it did not help.

I have now noticed that the problem decreases with less layers, even though used RAM may be higher... Seems to have something to do with the amount of layers. On this particular file there are about 15 layers.

Also, the file was started in CS3 32 bit, but after being saved in CS4 64 bit the file on disk is about twice as large. Does that have to do with the 32 to 62 bit change?

...and noticed something else. Large files (this one is 32000 x 20000 pixels) get saved by PShop with a PSB extension rather than a PSD extension... ?

well.. the size you are working on is REALLY big, the largest I personally paint is around 8000. (then scale it up using genuine fractals if needed) So I�m not really surprised you�re experiencing lag. I�m not sure technology is smooth for sizes like that yet.

Don�t know why it�s larger on the 64x.

I don't know why you would need such a high resolution. Even the Star Wars 360-degree mattepaintings were smaller I think.

The biggest image I've used recently was around 12k wide, and that was for a sky cyclorama that I used in a 3d animation.
