Yeah, how are you playing it before release?
Also, i bet Nvidia will release a driver in a day or two to help optumize it, being an Nvidia game.
I just hope it doesn't run as bad as AC4 does on AMD cards, especially given Nvidia's gameworks doesn't allow AMD to optumize drivers in any proper way.
I already have the NVIDIA optimised driver with SLI profile etc
Still runs like crap.
