The Witcher 3 will be a game that will sell graphic cards on PC. Regarding the tech part, The Witcher 2 was a beast, a game capable to compel the players to upgrade their computers. The third iteration in the franchise will follow that path according new rumors about the performance of this game.

These stories describes how is the game currently, bear in mind that the Witcher 3 was delayed time ago, so, CD Projekt still has time to improve the yield of this product.

PC

GTX 780Ti: the game struggles to run when higher levels of AA are enabled. Everything enabled and 8xMSAA, the game runs at 35-45fps and 1080p. This card can run the game at 60fps with lower levels of MSAA.

Consoles

PS4: 900p and 30fps.

Xbox One: 720p and 30fps.

Those settings would be equal than the minimum settings on the PC version. The source claims that The Witcher 3 on PS4 and One will look similar to The Witcher 2.

Apparently, Console versions of The Witcher 3 are unoptimized yet.
