I bit the bullet and installed Windows 7 64 bit. All rendering appears to have sped up - Except with Encore when I am using a dynamic link from Premiere and rendering for bluRay. OK I apply lots of filters in Premiere. My quad processor is running 100%, and 76% of my 8 gb of Ram is being used, but it looks like this part takes as long as in XP. Is there a setting somewhere in Encore that would change this or will we have to wait for a 64 bit version?
