For a list of supported nVidia CUDA cards go to the FAQ
For others, the nVidia Hack http://forums.adobe.com/thread/629557?tstart=0
I think a MINimum of 1Gig of video memory is required for CUDA/MPE support... does your card have that?
My Nvidia card has 1GB DDR3 Memory
with the notes on the NVidia web site it would appear that the GTS250 is capable of supporting Premiere (see my link above on Nvidia web site) ...it lists CS4 as supported ..... so one assumes CS5 also?.
This card is not listed by Adobe though
Since cards seem to share the same driver set - it will be interesting to try this out
I have ordered an upgrade to CS5 so will be checking that out next week
Supported and hardware MPE are two different things... go read at the HACK link I provided
Virtually "all" video cards are "supported" in that they will run your monitor
Hardware MPE requires either a CUDA supported card, or the hack
Have just purchased an MSI GT 740 Notebook, i7-720QM processor with the "GeForce GTS 250M" graphics card. (Win7 Ultimate.)
The part in quotes is what I added to the cuda_supported_cards.txt file and so far so good.
AVCHD is now rendered 'on the fly'.
I see the 5.02 update does include the GTX 470/485 now, but it does overwrite any additions you added.
Hope this is of some use to others out there. Just a shame it only has a max of 4 Gig and one hard drive ;-(
Still, its better than the machine I had before by about 50 times....
As far as I know, none of the "M" laptop nVidia cards are supported for hardware MPE
Well, I've just rendered a video on the laptop and it seems to work just fine, no lagging at all once it got going, just the poor hard drive dropping out at the start, then it flew through the render.
I guess YMMV.
The 'Hack' probably won't work on every machine, but these are my results so far....
