Photoshop Configuration
  • (Bigger Tiles) Remove tilde from program files/adobe/adobe photoshop cs2/plug-ins/adobe photoshop only/extensions/bigger tiles
  • Info => Info Palette Options => check => document sizes, document dimensions, scratch sizes, and efficiency
  • Scratch disk to separate volume, preferably solid state
  • Do not launch bridge. Edit => preferences => General => deselect launch bridge
  • Turn off palette preview (Layers, channels, paths) (Palette) => palette options => thumbnail none
  • Image cache is number of small images stored for display. Try 2.
  • Memory between 55% and 75%. Not to exceed 75%. Plug-ins and raw processor do not use photoshop memory allocation
  • History state stores entire image copy for plug-in or tile for local edit. Try 40.
  • Turn off font preview and/or check for damaged fonts
XP and Vista Disk Settings
  • On all disks optimize for performance and enable write caching. Especially important for usb drives, where the default is off. Computer management => device manager => disks => select disk => properties => policies
Vista 32-bit Memory Settings (XP similar but use boot.ini)
  • BCDEdit controls the boot configuration data source via a command prompt.
  • By default only 2gb of memory is exposed for application use. Solution: change application memory to 3gb (maximum) (3072) (increaseuserva). Note: Photoshop further reduces the memory it will use. If user-va is 2gb, photoshop will access 1.7gb. If user-va is 3gb, photoshop will access 2.5gb.
  • In default mode, addresses above 3.12gb are not utilized by anything. Solution: turn on pae. (pae). MSDN has articles on pae theory. Pae mode changes memory paging to allow access above 3.12gb for 32-bit.
  • In default mode, the operating system kernel occupies low memory, competing with applications. Solution: assign the operating system kernel to high memory (nolowmem)

Run a command prompt "as administrator." The following commands are entered:

bcdedit /enum
bcdedit /set increaseuserva 3072
bcdedit /set nolowmem true
bcdedit /set pae ForceEnable
bcdedit /enum

Output should look like:

nx OptIn
pae ForceEnable
increaseuserva 3072
nolowmem Yes

Turning Off Automatic Updates
The following appears to eliminate the annoying demand at boot up time for updates: In the popup which appears are boot up: (a) Click "preferences." (b) Uncheck "automatically check for adobe updates." (c) Uncheck all of the applications in "choose the applications to update" (d) Click ok (e) In the main screen click "delete all". This will clear the updates it is wanting to do right now (f) If all else fails obliterate or rename at least the exe files in c:\program files\common files\adobe\updater5\
