Hello,
i mounted a EVGA GTX 680 2GB (no Mac Vesion!) on a Mac 3,1.
The GPU works great with every software, in Resolve is very powerfull.
The big problem is the Decklink Studio: it is recognized by the system and in every software like Apple Color or After Effects... but not in Resolve!
Maybe a wrong installation sequence of driver/software?
My system:
MacPro 3,1
2 x 2,8 GHz
24 Gb Ram
SSD Samsung 512 Gb
PCI:
1 - EVGA GTX 680 Superclocked Signature - Windows Version
2 - Empty
3 - DeckLink Studio
4 - Fiber Channel board
SO: 10.8.4
Cuda: 5.0.61
Thanks in advance
