Dragon Age: Inquisition and Far Cry 4 both come out today. As one might expect, AMD and Nvidia have released new graphics drivers for the occasion.
AMD's Catalyst 14.11.2 betas promise peak performance in both titles. Radeon owners can look forward to a 50% boost in Far Cry 4 "in single GPU scenarios with anti-aliasing enabled." Dragon Age: Inquisition gets a 5% increase under the same conditions, and AMD has added a "optimized CrossFire profile" for that game. There are evidently issues with CrossFire in Far Cry 4, though:
The AMD CrossFire™ profile for Far Cry 4 is currently disabled in this driver while AMD works with Ubisoft to investigate an issue where AMD CrossFire™ configurations are not performing as intended. An update is expected on this issue in the near future through an updated game patch or an AMD driver posting.
CrossFire isn't completely sorted out in Dragon Age, either. The release notes say AMD is working with BioWare to address "flickering" that is "sometimes observed in Dragon Age: Inquisition on a limited number of surfaces in AMD CrossFire™ configurations."
Nvidia's new 344.75 drivers are tuned for more than just the new Far Cry and Dragon Age titles. They also contain optimizations for World of Warcraft: Warlords of Draenor, which was released last week, and for The Crew, which is due December 2. The release notes (PDF) mention an alt-tabbing problem that crops up with The Crew and dual-GPU Titan Z cards, but that seems to be the only issue affecting the fresh crop of games.
Unlike the Catalyst betas, the Nvidia drivers bear Microsoft's WHQL certification. They also support multi-frame sampled antialiasing, otherwise known as MFAA. This Maxwell innovation uses several tricks, including taking pixel samples from previous frames, to reduce jaggies without sapping performance. MFAA doesn't require engine integration like Nvidia's TXAA, but PC Perspective says the scheme only supports 20 titles right now.
