This is a great topic and I too am very interested in figuring out how to best optimize the hardware to render faster/better in several programs such as Adobe CS5 and CS6, as well as Sony Vegas 12 Pro. 

I have 4x GTX-680 Classified (4GB) and no matter what setting I tweak, Sony Vegas seems to take a LONG time to render stuff. For instance, a 15 minute 1080P video with a few effects took me more than 1.5 HOURS to render! This is also with an OC'd i7 3970X, the fastest X79 processor out there!

I selected "Render with CUDA if available" to use GPU Acceleration and EVGA Precision X shows that the GPUs are being used (although not to their full capacity) and the CPU is used about 80% during rendering.

What are some optimal settings in Sony Vegas 12 Pro for rendering in 1080P? I really want FAST rendering and that is one of the main reasons I am going to get the GTX-Titans since its CUDA cores and GPU Compute is not gimped.

For those with GTX-680 Classified, what are the best settings?

Any advice on this is appreciated.

Keep in mind, Fermi had a 'hotclock' where the shader frequency was twice the core; but with Kepler the hotclock was removed and the shader and core are equal.  So while the Kepler cards have more CUDA cores, they aren't running as fast, so you can't look at the number of CUDA independently and expect equal scaling.

For instance, in purely GPU-intensive gaming (which uses the graphics card much more), GTX590 (1024 CUDA at 1240MHz) tends to match GTX680 (1536 CUDA at 1006MHz), and therefore Titan's 2688 CUDA at 837MHz isn't that much better than your total of 1440 CUDA at 1400MHz used under similar GPU-intensive circumstances.

Mathematically, since purely GPU-intensive scales with number of CUDA multiply by their base clock, you may see equal performance while using 66% less power since Titan uses as much as GTX480 did at 250W.  So the $1000 will mainly pay to reduce your power consumption as Titan = 3-way SLI GTX480, for the most part.

For what it is worth, 2-way GTX680 is faster than Titan for the same price, that route would give you around a 26% gain for a cost of about half the power.

What frame rate are you rendering at? I do 30-40 minute videos at 1080p 30fps with 4-5 channels and mine take 2-4 hours. I found out that Vegas 12 has a LOT of issues with GPU acceleration, I would go back to Vegas 11 if possible.

I am running an i7 920 with GTX 480's so your's should be much faster than mine.

Toss me a screenshot of your rendering settings and your project settings and I can throw you some advice.

Hi,

Here are the "Render As" settings I use:


Would greatly appreciate any help with this!

Yeah I already see a couple issues but I don't remember the exact numbers to change them to. I just got to work so when I get home i'll let you know what to do. Can you also paste me a screenshot of your project settings? When you click on file >> new, you should see a window pop up.
