RGB Curves crashing Premiere after update

Question

I just updated Premiere CC and every sequence that uses RGB curves has been crashing on me. Premiere starts acting as if it is being asked to do way to much. The video starts displaying still images every ten seconds from the video until the entire program becomes unresponsive. When I pass the buck to media encoder and watch my CPU usage it tells me that I am using 775% of the CPU. I've opened sequences where is hasn't had curves and applied them and immediately the program begins to slow down and crash. Anyone else having this issue?

Hello,
I'm sorry for the trouble this is causing. We are aware of the performance issues that were introduced in version 7.2 with certain AMD GPU cards.
We're investigating the problem now.
I know this is not ideal but in the mean time here's a few workarounds:
- Revert back to 7.1
- Disable GPU acceleration when using those effects
Here's a list of effects that seem most problematic:
*Fast Color Corrector
*RGB Curves
*ProcAmp
*Edge Feather
*Lumetri Looks
These effects do not appear hinder the performance in my testing:
*All Blurs Effects
*Three Way Color
*Crop
*Garbage Mattes
*Levels
Again, I apologize for the inconvenience.
Best,
Peter Garaway
