i found an odd behavior
after 10 or 15 adjustament layer ,the levels adjustament layer become slow or to be more specific not very responsive , with opengl turn on
i have to be honest it's about only the levels
with opengl Off the levels adjustament is always perfect
i did notice with openglon this icon , i added a screenshot with a red arrow
well if i click on the icon , it takes 2 seconds and the levels become very fast with opengl on
is there a way to let cs5 to re-calculate the histogram everytime i add a levels adjustament layer?
why does it happen with opengl on ?
If it makes a difference with open GL on or off it is likey your graphics card and/or driver. First step would be to see if you have latest version.
i updated the last ati drivers and i used a tough ati video card
and it doesn't fix it
can you replicate my issue?
i found some information here http://forums.adobe.com/thread/681729
i googled cs5 opengl on vs off , and i found some benchmarks , i don't know but seems cs5 with opengl OFF is faster, really don't know
