:( tried Photoshop 4 no GPU support for XP 64Bits !!!

[beestee]

My CS4 was really laggy on Vista 64, it was much slower than CS3...then I found the openGL option and have found that the performance is leaps and bounds ahead of CS3 now(on an 8800GTX). Seems that using the windowed trick has pushed the performace even a little further. I am currently getting a kick out of the dynamic zoom and pan. Been looking for an excuse to use the Content Aware Scaling, but havn't found one yet.

hmmm

Its working very well now even with large files.
videocard: nvidia 8800 softmodded to quadro 4600

hey tammo, I have a 8800 GT at home and a GTS at the office, but I haven't succeeded in modding it to quadro. How did you do it? I haven't tried the latest Rivatuners, since I thought they didn't work from 78xx on.

Trial should be here:

You need an AdobeID tho.

I wouldnt really suggest softmodding cards. Tho it's been a while since i last tried. But it's a lot less stable and you never know if a specific problem is due to the modding, the driver or something else in the system.

The official registry mod is available here:

And it helped TONS for me too. Performance is actually pretty okay now.
