Nvidia has released a tech video demonstrating the bulging muscle of GeForce GTX in Assassin's Creed IV: Black Flag. Optimized God Rays? Yes! TXAA? Why not!
For obvious reasons the 2 minute long tech video is best viewed in full 1080p to catch the visual differences between fancy techy stuff being off or on.
Assassin's Creed IV: Black Flag releases on PC November 22nd in the US, 25th in EU.
