The new field blur and and tilt shift filters worked a few times but are now greyed out in the menus. Any ideas why? Thanks.
I've had this happen to me a few times on 10.6.8 with a 4890 vid card. I have the center blur control but no oval control points. Also, will the new blur filters work on smart objects in the final shipping version of CS6? It would be really disappointing not to have these filters on smart objects.
Did you check the settings Chris mentioned? Your issue sounds like there might be a video card or driver issue, which can disable the GPU related features and give you a lesser version of the blur filters. See this link for some troubleshooting suggestions. See if issues with the video card have disabled - Edit>preferences>performance use graphics processor. Also check the advanced settings drawing modes. Be sure you have the current driver (system is updated and current on mac or go to the video manufacturer's website for pc) . That is often the cure.
You might want to copy your system information (photoshop help>system info) here for us to look at.
I am not quite sure how to log in that the problem seems to have gone away - but thanks for the replies. It was clearly an intermittent issue and I wasn't ever able to pinpoint why the filters worked sometimes and not others. But they seem to be working now.
