Titan with CUDA fails on vegas Pro 12

Hi;

We have recently purchased an nvidia-titan, and installed the nvidia beta driver 314.21 (the official driver make vegas crash frequently during various operations) Now with teh Beta-Driver the rendering of an mp4 video without CUDA works just fine. But rendering with CUDA still shows 2 issues:

1.) There is no speed increase at all. (Same render time as without CUDA)
2.) At the end of the rendering Sony Vegas crashes.

Here are the render settings:

- MainConcept AAC/AVC
- size: 1280*720 pixels
- framerate: 25(PAL)
- aspect ratio: 1
- maximum bps: 18.000.000
- average bps: 12.000.000
- Encode mode: Render using CUDA if available
- enable progressive download

Is there anything we can do to get the power of titan used by Vegas ?

thanks

I think you can benchmark preview too by making a test project, like "render test 2010" but with more compositing. I am very happy with my system but to be honest, preview of scrolling text with the Sony text generator is still not running at full settings; I have to run it at "Good Full" or sometimes on "Preview Full". Also 32bit projects with 4:4:4 footage or 4K RAW will be tough to work with unless we use proxies.

Quadro cards are still based on the same chips as consumer cards. you can find all the GPU chips and cards in this link http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_600_Series
GK 104 & 106 are used in the K600 up to the K4000 but the GK104 in the K5000 has a different code name for the consumer card; GK104-400-A2 and hence might be a "stripped down" version that is missing the compute part of it... there are plenty of speculations on the Internet about that too.

I don't think you can ever have it all as with new technology on one side comes new one on the other one. PCIe 3.0 has not even been fully utilized yet.

It would nice if Vegas had an internal or command line setting to dump audio and let preview go as fast as it can for simple benchmarking. Otherwise, we just have to create a project that does not preview well on what we have and see if a better GPU card helps. Not exactly something review sites will ever do.

Yes, It appears the K5000 is the GK104 chip and should perform similarly. I looked at the Nvidia site and a technical site. Still ripping people off. Who knows if some things are hardware jumper enabled in the package which is commonly done in the chip world. That cannot help 64-bit FPP performance, as the execution unit are literally not there, but apps like Vegas don't typically care about 64-bit floating point numbers.

I have only followed the graphics cards and tesla and then only the top models in the Nvidia world.

I am just really appalled at Main Concept and their development model, or lack thereof, with the AVC OpenCL and CUDA encoders.
