I was running version 12 for a long time (and have been a customer since V10) but was hoping for Sony to get the GPU acceleration running for CUDA based cards. I use K1 and K2 cards, and two with GTX750ti cards. And none of then can use the GOU to speed up rendering.
When they posted on the website they would give me a free upgrade to V14 if I upgraded from V12 to V13, I thought I could trust the advertising (my bad - I should have known)
But seeing it wont happen, I am not really keep on just throwing that amount of cash away
