First few tests are showing v2014 to result with render times about 20% faster than v11.5. And lighting is really very nice. In the image below notice the color bleeding. All light (global radiosity) is bounced from a single quadratic point light with a power setting of 5. No sunlight. No direct lighting. The bleeding is from a bounced shadow. Not bad. Also what looks like a little bit of bloom at the bright spot. Render time was 1 min 52 with Ultra settings.
