cs5 levels slow (sometime not very responsive) with opengl on

Mar 30, 2012 9:56 AM

hi

 

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 normal?

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 ?

 

 

thanks

cheers

    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.

    thanks

    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?
