Post-Production : Premiere 2017 bugs and large render times by Nick Sebastien Theriot

Has anyone else noticed unusually large render times in the 2017 release of Premiere? I'm running dual 6gb GPU's on a MacPro cylinder (and in FCPX and Avid it is really fast, even for 4K) and it takes hours for clips to render. This is why I like FCPX, but I have to use Premiere to be able to use an up converting plugin from RedGiant Shooter's Suite. Adobe is worse than Apple with dropping buggy updates. Also, SpeedGrade isn;t get an update, which may be a blessing, but the Premier to SpeedGrade workflow doesn't still work properly for me- another downside for Adobe.
