I try VP14 and i have a GTX 780. When i render a small sample with MainConcept AVC it takes 31-32 seconds with CUDA enabled and 31secs with CPU only. I have a i5 4690. GPU rendering is enabled in Preferences.
Is this option just a placeholder?
GPU accelerated rendering of MainConcept AVC/AAC only works up to the GTX 580. I doubt you will ever see that change.
Yeah, who needs cards newer than 2010 in editing apps released in 2016? C'mon Magix...

I tried using Sony AVC encoder and the same sample video takes 12-13 seconds with CPU,GPU enabled, GPU disabled. (used 1080p settings). MainConceptAVC took 22seconds with 1080p res.
Basically no difference with Sony AVC either.
Il take it as non-working and if it's working then it's working badly. I was hoping for some true real difference in this new version of VP. Thanks anyway.
Assuming Magix hasn't changed GPU compatibility since VP13 then the definitive answer to this question is given by Nick Hope above. Sony never made the NVidia 6xx, 7xx, 9xx etc. cards compatible with Vegas. I don't remember any reports of success with these cards. Perhaps there were some complicated workarounds but until Magix improves GPU compatibility then we're all out of luck. Virtually all the video rendering software I own is now fully compatible with GPU except Vegas.
Vegas 13 works with my Nvidia 980. By works I mean the Vegas video engine (compositing, effects, scaling, etc). The Mainconcpet AVC or Sony AVC file encoders are another matter.
MC AVC only ever supported Nvidia up to 5xx (via CUDA) and AMD up to 6xxx (via OpenCL).
If my memory serves me my AMD 7950 did work with Sony AVC but my Nvidia 980 does not. This does not really matter as Sony AVC only gets a tiny GPU boost. I once measured all that when way back when I had an AMD 5850.
Regarding Sony AVC I am not talking about Quicksync support. That is something completely different.
Back to Nvidia in Vegas 13 (no 14 yet). When using pure Vegas effects, aka pure OpenCL, it seems to work well. Not as good as AMD I think but "well". AMD being good/great. However if I use third party effects that use OpenGL GPU acceleration (NewBlue, Hitfilm) then performance really toilets. It could be that the OpenCL->OpenGL->OpenCL transfer is not so good on Nvidia compared to AMD.
Some effects like Boris Continuum 10 and Twixtor Pro are accelerated using GPU in Vegas Pro 13 on my system. Not sure if they'll need to be updated for VP14. It's hit and miss with NVidia and Vegas. What we need is consistency through out the whole work flow.
When Boris uses GPU it is typically OpenGL. Don't know about Twixtor.

I'm not really sure but when I've tested rendering a project to AVI/MXF/MPEG with BCC/Twixtor it's definitely faster with GPU on. Sometime significantly.
