Will the sapphire r9 390 nitro fully support DX12 ?

Sapphire r9 390 nitro 8 GB ram .

 

If you mean by "fully support" run a dx12 game, then yes. If you mean use all of DX12's features then no.

No card today fully support all DX12's features.

I would not worry about it though, R9 390 will do fine. If you checked latest Hitman dx12 benches 390 is performing even better than gtx980.

 

But best card for the money.

 

You can also buy a 290X with the same features.

 

nope that extra 4gb vram is really starting to make a difference.

 

He already have 390.
