Source - AVC 25fps progressive, 4096x2160x12
Clean install Windows 7 x64
Processor: Intel Xeon CPU E3 - 1231 v3 3,40Ghz
RAM 16GB
Editing:
VEGAS 12 ....... 3 - 6 fps (Preview (half)
VEGAS 14 ........ 25fps (Full Preview).
When Transition simple or simple ProType Titler in V14 is 20fps.
After repeated GPU on / off and retrying is simple Transition 15 - 3fps. I've never reach 20 frames.
Rendering 10sec. shot, the quality of BEST

Intel HEVC (ignoring my settings 4096x2160. Renders 3840x2160) ----- 2:40 minutes
Sony XAVC - MXF - 0:37 minutes
I would welcome a truly functional feature - NO-RECOMPRESS RENDERING FOR AVC HD AND 4K.
Conclusion:
A simple cut is a good V14. On complex projects we will have to wait for full support for the newer GPU.
AVC MP4 size is 46 megabytes, Sony XAVC has 275 megabytes, Magix Prores is by the quality of 850 megabytes - 1.27 gigabytes.
Working Processor:
editing with GPU: 43%
editing without GPU: 32% (without GPU works less ???)
rendering GPU / CPU: equal to 85 - 90%
GPU function for GTX970 is purely decorative. I look forward to VEGAS 15
