Hi,
DS v10 is pretty tightly written around the GPU abilities of the Quadro cards, therefore you may well have problems with alternative Nvidia cards.
I got v10 working under bootcamp with a 6800 card by following this procedure:
1. Open the nVidia control panel and go to ‘Manage 3D settings’
2. Click the ‘Program Settings’ tab and click ‘Add’ to add a new program
3. Select ds.exe from C:\Program Files\Avid\DS_v10\
4. In the settings list, scroll down to “Threaded Optimization” and set it to OFF
5. Click apply
This worked for me and others so may well work for you.
Good luck,
Tone 🙂
