I'm in CS4, and I'm painting white on a black layer mask, and I'm getting thirty second delays between my brushstoke and it taking effect? What going on???

CS4 is advertised as being much faster than CS3. I went back to CS3 and the speed is fine/normal in CS3.

Also bizarre is the brushstokes in CS4 look like this (click new window):

As opposed to CS3, which look normal like this:

You are probably experiencing difficulty with CS4's new OpenGL support for 3D video cards, as are many other users. The discussion of this issue has raged on Adobe forums (http://www.adobeforums.com/webx/.ee6b366/?@384.r3n9iUauZ6b@) for several months. Go to the forums page, and you'll see a number of topics on this subject. If you're brave, look for the main thread there entitled "Photoshop CS4 is a disaster", which had over 800 posts the last time I checked. If you start a new thread there, maybe you can get someone who has followed the issue to summarize the current situation for you.

I experienced similar problems when I first installed CS4 and put in a new 3D graphics card to take advantage of the new 3D features. I went back to my 2D Matrox card and have been waiting for the OpenGL problems to be sorted out. There is a new CS4 version out which is reported to fix at least some of the problems, but I haven't had time to check it out yet.

One place to start is with Adobe's list of tested graphics cards: http://kb.adobe.com/selfservice/viewContent.do?externalId=kb405711&sliceId=1. Before the new CS4 version at least, some people with cards on the tested list were still experiencing problems. I'm not sure what the latest situation is.

Something is wrong - CS4 should be noticeably quicker than CS3. Maybe check out GPU and OpenGL settings in Prefs.

As for the brush, it looks to me like you've got a texture or pattern. Reset the brush? Check you've not enabled a layer style.

This is almost certainly the OpenGL problem.

Well the open GL pref is greyed out. Probably becuase my computer is four years old. I just read that for CS4 for work properly you need a state of the art new computer ( ie mac pro...)
I think it's outrageous ADobe does not broadcast this. I'm going back to CS3. Oh well.

The brush was just a normal brush. I triple checked. I don't get it.

One of my computers certainly isn't start of the art, and CS4 works fine. I don't know enough about OpenGL and Mac, so maybe Peter can comment more.

I agree must be your PC/MAC - I have found CS4 to be much much faster and more stable

My DP G5 is 5 years old. CS4 runs about the way CS3 did on both OSX 10.4 and 10.5. Open GL is grayed out in the Prefs and most operations run well. Saving a large file seems slow, but no slower than CS3 on 10.4 - I have prefs set for full compatibility when saving a file.
