Ok, I've been trying to figure this out and figured I would give this a try... After my laptop recently imploded on itself I've been using an old Dell (P4 3.00GHZ, 512MB RAM) desktop for my Photoshop needs... I upgraded to CS4 when I switched to this machine and it works fine until I try to do an HDR (32 bit) image; it shuts down Photoshop and when I reopen it has a message stating that it has encountered a problem with the display drivers and temporarily disabled GPU enhancement... I fully upgraded the drivers for my video card (Intel 82865G)... It still does it... I can use Photomatix and create an HDR image... I'd like to get this working so I can use Photoshop and not have to switch between the two programs all the time... Any ideas?
