    Curves performance has decreased


      Since maybe a month back, curves performance in lightroom has become so slow and unresponsive that it's nearly useless. I usually export to photoshop when I use curves, so it didn't bother me too much when the problem began, but it's worsening and i'm starting to worry about what the problem might be. Basically it takes maybe half a second to react to my mouse or Wacom movements, and takes a second or two to show the result. It makes the process painfully slow.

      I have no performance issues with any other tool (maybe the brush tool with a very large and smoothed brush, but everything else run smoothly), and curves runs fantastic in photoshop, so it's just a lightroom problem.

      Any ideas of what might be happening?
