What brand and model of graphics card do you have?
You updated the drivers from graphic card makers website?
(drivers updated by windows itself are almost always out of date)
Also, with some laptops you may have to get the update from the maker of the computer.
If in photoshop cs4 you go to Edit>Preferences>Performance, uncheck Enable OpenGL Drawing and then restart photoshop cs4, does that make a difference?
It never seizes to amaze me how many possibilities and switches CS4 has.....
It's a Lenovo with an intel graphics device and the driver came from intel. Flipping the switch in performance did the trick.
Thanks for the help!
That just means it's likely the graphics card drivers causing the problem.
If you leave OpenGL Drawing off, then you won't have gpu features, some 3d features and 3d stuff might be slower.
Anyway, you can read more about it here and see if you want to pursue trying get your graphics card to work with photoshop cs4
If you do, can you post the contents of the Help>System Info from within photoshop cs4?
Hmmm. For now I'm happy in 2d. I'll get back to it when I want to go 3d.
