I still have an older FW card inside my PC, but surely has the T.i. chip on it, very important for the N12.
I know W10 officially does not support FW anymore, but everything still works great so I am very happy.
I did have an issue a few years ago while buying an extra Graphics card(Nvidia) for my 3th screen. The drivers for the Nvidia card interfered with my FW card. So I swopped that one for a very simple Radeon Card and since then the N12 runs just fine.
