Nvida Cuda GPU

[Tim Kolb]

The approved cards are the GTX 285, the Quadro 3800, 4800, 4800 for Mac, and the 5800.

The Quadro CX is also enabled I believe if you have one of those installed.

Tim and others,
Yes, I see that on their web site, but is the so called “Mercury Engine” same as CUDA technology? If so, there is a whole list of such cards on NVida web site (see below). The so called “approved” list, does that mean others are excluded?

I guess I am asking, for not so serious users who want the least expensive yet somewhat reliable performance, which one is my best option.

Sincerely,
Perry

There’s a work around for just about anything…

I’m using a GTX260 and I got up to 4 layers, so far his reference in the other article he made seems true about the 285

The GTX285 is what? 300? 400 USD?

How “not serious” do you need to be?

The hack mentioned in the link isn’t hard to do…at least not as hard as getting any sort of technical support after you do it of course…

Premiere Pro users have been squawking about dependability for how many versions? Now when Adobe has vigorously tested a group of display cards and ‘certified’ them…users look for a way to run something else.

Tim and Vince,
Thank you very much for your insights. Just for my stats interest, anyone, can you do some test for me? If you put a HDV (30fps 1040p NTSC Video) on a timeline: Track1 original Video, Track2 25% opacity + Quick Blur; Track3 25% opacity + quick color correction (change some color) & Track4 25% opacity + video distort. What’s the different CPU usage do you get?
I have a QUAD CPU Intel Q6600 (average CPU usage around 40%) with Hardware Acceleration with Nvida GT 240 1G or GTX 260 898MB (I saw not much difference). There is some stuttering as well. BTW, I have 8G RAM, plenty of HDD. If I use software only CUDA preview, I got around 60% CPU usage. Is this the best I can anticipate, with these cards and how about with high end cards?

P.S.: I did the hack Vince suggested. I am just curious for a higher end card, does it really get me any better preview effect.

Sincerely,
Perry

Sorry, I meant 1080p, finger went too fast.
