Photoshop CS4 on Vista x64 - Nightmare!

System:

Windows Vista Ultimate (x64) Service Pack 1 (build 6001)
3.00 gigahertz Intel Core2 Extreme
8126 Megabytes Installed Memory
NVIDIA Quadro FX 1700 Graphics Card: Driver Version: 7.15.11.7813

Firstly, when I installed CS4, I downloaded and installed the latest driver for the Quadro FX 1700, namely, the 181.20. It was a nightmare, so I have rolled back to the one listed above. Also, "Enable OpenGL Drawing" is turned off in Preferences.

My main problem is with Bridge/Adobe Camera Raw(ACR) 5.2, not with Photoshop CS4. It (Bridge/ACR) is riddled with memory issues.

Memory in PS/CS4 is set to 60%.

When using ACR to process 120Mb Canon files, I keep getting the dreaded "There was not enough memory." error message. But, when Bridge/ACR are running, no other program is open. This error message never appeared in CS3.

It is now so bad that I have to process one file at a time. Even then, I am getting a new error message when trying to click from one processed file to the next one in the ACR window: "Could not switch, there was not enough memory."

To fulfill a deadline, I have had to revert back to CS3.

Can anyone suggest a fix?

CS4 64bit has been a huge disappointment as far as I'm concerned.

Help, please.

lol, that's interesting. I'm using Photoshop CS4 64 bit, and it works prettier than CS2.
My graphic card is Nvidia Geforce Go 7200, which Vista gave 2.7 point.

Thanks for the reply.

1. How much RAM do you have and what do you have it set to in Photoshop's Edit/Preferences/Performance?

2. My problems lie almost totally with Bridge/ACR 5. Do you make heavy use of them? i.e. lots of files open in ACR and lots of adjustments made to those files?

Thanks.

I have 2 GB ram, but I don't use bridge. Sometimes I deal with very high resolution images, but as I said, it works prettier than CS2.

I didn't change that much preferences that may affect performance. IDK, maybe you should re-install?
