Recommendation Video Card that Vegas 10 utilizes

[Bill Mash]

I ran a test render with my ati card three times to get an average time to render. Shut my system down and installed my Geforce 430 with CUDA and fired up the control panel to watch the GPU performance.

Kicked off the same render three times with pretty much the same average time (7:01 versus 6:59). All the while the Cuda control panel shows flatline for GPU usage with an occasional ripple to 2%. From this I assessed Cuda wasn’t buying me squat on my XP 32bit system.

Directcompute showed as off in GPU-Z upon investigating I come to find that I needed Vista on Windows 7. My suspicion is the CUDA architecture is being accessed by the directcompute windows API that XP doesn’t support. Poking around my suspicion appears to bear fruit below.

I’m betting a see the CUDA performance kick when I upgrade to Windows 7.

Were you rendering using the Sony AVC render type? This is the only one that is GPU accelerated (unless you disable it).

CUDA and DirectCompute are competing API’s. They don’t use each other; the are alternatives. Read the article you referenced carefully.

Actually I’m wrong. 🙂 DirectCompute does use CUDA for DirectX 10/11. That still doesn’t mean that CUDA isn’t available in Windows XP. It just means that DirectX doesn’t take advantage of it in XP but other applications can.

Wholeheartedly agree. Unfortunately one of those applications isn’t Vegas:-)

I read all this topic a few days ago because I was looking for infos for a new computer for video editing.

I just bought an HP Z600 and a Quadro FX 4000.
Windows 7 64bit, 16Gb of RAM, 2 Hard disk of 1 Tb each one.
I wasn’t sure about the video card, I first ordered a GTX 580 (last model) because of the higher CUDA cores, but this card needs 2 cables of 6pin and 8pin from the PSU, that I don’t have on the Z600.
So I moved to the Quadro 4000.

I will let you know how it works.
