Cubase 8 overloading/glitching out in 32 bit mode

I’m using Cubase 8 on OSX 10.8.5 in 32 bit mode. I only had 4 plugins loaded up, but Cubase started glitching out when I used Omnisphere and ValhallaRoom. I could hardly hear the audio it was breaking up so much. Just these 2 plugins overloaded it. Anyone else having glitching issues like this?

Yes. In 32-bit and 64-bit. Seems to build over time. I’m on 10.9.
