Still waiting for Adobe to fix apparent problems in Photoshop CS4 within their brush and OpenGL GPU video engines. To date, I have found no workable resolutions for all of the similar complaints spread across web forums to address brush lag, Wacom tablet pressure sensitive functionality broken, and general video flakiness. Photoshop CS3 installed on the same machines are reported to work fine. I spoke to both Adobe and Wacom technical support, and they both acknowledged the problems, either directly or indirectly. Wacom said they sent a letter to Adobe "two weeks ago" reporting the tablet pen pressure sensitivity problem. Adobe had me try every tweak in their book, to no avail, and then privately acknowledged the huge number of user complaints. My system is no slouch either, and met with no qualms from Adobe, so one can assume this is a big problem.
