On my Retina MacBook Pro with PD7 and Win8 I was getting a score between 110-115 FPS for Steam's Lost Coast video stress benchmark with highest settings at 1920x1200. After upgrading to PD8, the score went to 85-90 FPS, all same settings. I have the VM configured as 4 CPU, 4GB RAM, 1024 VRAM as before. That's about a 20% loss. Where's the 30% increase? I was really excited about that!
