I'll test it.

Press SHIFT when click Options>Preferences - then you will notice new 'Internal' tab appear. Find GPU, and set it to 'TRUE'

Is this what you are looking for?

It did work, but I noticed the rendering time and speed did not improve at all. I was pretty much lucky at that point. So until the VEGAS team fixes and adds in GPU Render Acceleration, I may have to use Vegas Pro 12 for certain videos, for now.

GPU redering isn't officially supported beyond NVidia 5xx cards as far as I'm aware. I'm still waiting for this feature to work with my 7xx cards. It's probably the one feature request most in demand.

I just got a response back from MAGIX that they will make an update for newer NVIDIA gpu support.

Did they give you a time frame?

More to the point exactly what is to be updated.

There are a number of items in Vegas with regards to GPU. An update of timeline OpenCL support to work better on Nvidia implementations. While OpenCL is generic you can do things in certain ways that can lower performance on a given implementation. Luxmark is an example here.

For the most part, MAGIX cannot do anything about the file encoders. They do not write them. Mainconcept does and Mainconcept AVC still does not support modern GPUs. Nvidia or AMD. MAGIX does control the Sony AVC encoder so maybe something there. Mainconcept has stated that they will have Nvidia support (CUDA, OpenCL, NVenc, ?) on their HEVC/H.265 encoder in 2017. Maybe MAGIX will license that, but that helps no other codecs but HEVC.
