1. Re: Some GPU questions
Mylenium Oct 20, 2008 7:03 AM (in response to klsteven-vBdprK)Mmh, might be a limitation in the implementation of OpenGL. In theory you should see no artifacts at all on your card. Color Matching enables an extra processing step which is required for non-sRGB images, so you cannot really go without it if you use hardware accel. I'm just not sure how it all goes together, as I'm a video-centric user and usually forego any of that color profile stuff. Maybe someone more qualified can provide some better info to you.

2. Re: Some GPU questions
klsteven-vBdprK Oct 20, 2008 7:20 AM (in response to klsteven-vBdprK)Now I made a black/white-gradient in ProPhoto RGB. Wow, this is really ugly.
Banding and red/green shifts within that banding if "color matching" is on. But without "color matching" there`s no colormanagement at all.
Looking at that same file in CS3 everything is fine! -

klsteven-vBdprK Oct 21, 2008 4:19 AM (in response to klsteven-vBdprK)Can anyone replicate this behaviour?
Just make a B/w gradient in ProPhoto RGB and see if you get banding.Then turn off "color matching" (in Open GL`s advanced settings) and test again. Then test again without Open GL. -

(Maasel_Sull) Oct 22, 2008 10:42 AM (in response to klsteven-vBdprK)Funny bug in CS4, when I enable OpenGL I cannot see picture. Its grey frame. Picture shows up only when I moving it.
