I tried all suggestions: update drivers for graphics adapter, update DirectX, hacking the registry, deactivating antivirus software.... No matter what I did, with or without OpenGl drawing activated: the brush was terribly slow, unusable really...
So I gave up and went back to CS3: works like a charm, no problem. A shame though, and regretting some nice CS4 features.
Wanted to give it 1 more try, and this time looked at some BIOS stuff. Tried a few things with no luck UNTIL ..... enabling palette snooping. That did it: CS4 flies, no more lag..... feels even a bit faster than CS3.

Hope this will help others !
Happy New Year, Gelukkig Nieuwjaar, Bonne Année,

Still, if it works for you and helps others that's a GREAT call there Rudolph.
I checked my Asus P5Q deluxe, out of curiousity, and it doesn't have the snooping palette setting. No biggie as my system runs well with CS4.
you can reset it via the clearCMOS jumper on the motherboard.
if you have the manual and know where the jumper is. might be worth finding before fiddling if you're not 200% comfortable...
After using Photoshop CS4 since it's release with virtually no issues and really enjoying the new features I started Photoshop this morning and experienced all of the issues in this thread!
Extremely slow and lagging brushes.
Jittery Zoom tool operation.
Text - very slow! I could type a 5 letter word and sit back in my chair and wait for it to catch up!
etc. etc.
If this would have been like this when I installed I would have immediately reverted back to CS3, completely unacceptable!
Turns out Microsoft update installed a new set of NVIDIA drivers!
I went to the NVIDIA site and downloaded the latest drivers, installed them and now everything is good again.
Processor: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (2400 MHz)
Operating System: Windows Vista (TM) Ultimate, 32-bit (Service Pack 1)
DirectX version: 10.0
GPU processor: GeForce 8500 GT
Driver version: 181.22
Total available graphics memory: 1790 MB
Dedicated video memory: 512 MB
System video memory: 0 MB
Shared system memory: 1278 MB
Video BIOS version: 60.86.48.00.16
According to the BIOS Setup section of the User Guide: "When set to enabled, the pallete snooping feature informs the PCI devices that an ISA graphics device is installed in the system so that the latter can function correctly". Pallete Snooping is disabled by default.
I believe this explains why Open GL does not function properly on some systems. Why this feature is disabled by default on boards with non-integrated video is strange, though.
BTW, BIOS changes are no big deal if you have a Users Guide and a reasonable degree of reading comprehension. If not, ask someone who does that can assist you. Asus tech support is first class.
Beta 2 (which I think folks can get upon request) is quite a bit more OGL friendly, but it does not cure all. I (for one) can not use OGL without a steep performance hit. Everyone needs to know their OGL level and compliance. AE ships with a compliance checker. I would think that it could be a download from Adobe -- or maybe some shareware site. You really need OGL 2.1 or above. If not, game over --> just bite the bullet and get a new card.
