colour difference in processed files

In our studio we recently switched to capture one 5.0.1 from capture 3 with a short testing time on capture 4
the new capture already fixed a lot of the problems we experienced with version 4, however we noticed a systematic difference in luminance and saturation in the files between the Capture one viewer and the processed file opened in photoshop. the file is roughly 1/4-1/2 stop darker and is more saturated.
we work on colour calibrated eizo displays and the files are acquired using phase one's backs profiles (we use a few different ones) and exported in Adobe RGB (1998)
I know that the Adobe RGB '98 is an old and in many way outdated profile, but due to business reasons it's not an option to use anything else.

I can't imagine all the difference derives from the conversion from the camera profile to adobe rgb...alsco because in capture one 3 and 4 was not happening, still using the same profiles...

any help would be very welcome!

Thanks

  Hmm, difficult to say. One thought that came up with me was Photoshop CS4's OpenGL setting. Familiar with it (Preferences, Performance)?

  Set the Proof Profile, Output Profile and Default Monitor Profile to Adobe RGB 1998. Redundant to be sure but it leaves no room for error in the color workflow. With that setup what you see is what you get, and if not the issue is due to settings in Photoshop. Once you determine that everything is copasetic with Capture One you can change the settings one by one to see which is the problem. Usually the default Monitor Profile.

  Hi, thanks for the replies,
  @Paul, we are on PS Cs3...
  @ Drew,
  when you say to set all the profiles to adobe RGB 98 what do you mean exactly? at the moment my settings are:
  display profiles: are the ones created by the eye one Gretagmacbeth,
  capture one profiles:
  capture: default profile for the digital back,
  process recipe: adobe RGB (1988)
  rendering intent: Perceptuel
  Ps Cs 3:
  settings: Custom
  RGB: Adobe RRGB (1998)
  CMYK: iso Coated 300% (ECI) because is the one the printers we work with use
  gray: dot grain 15% very rare to work with grayscale images
  
  any more help welcome,
  
  thanks a lot!
  Marco
