Nvidia is really tooting their graphics technology horn a lot lately, probably trying to grab some attention back from AMD.
On the future-tech side, Nvidia showcased its GI Works and Optix tech and explained how Gameworks is its development vision for Nvidia-based gaming (it will even support Linux, OSX, and Android platforms).
So what about PC games you can play now? We previously looked at an impressive tech demo for Assassin’s Creed 4, and in that vein, Nvidia has also released some 4K resolution screenshots of the game in action.
According to Nvidia, the tech on display (which goes beyond what the next-gen gaming consoles are capable of) includes:
- Nvidia HBAO+ adds realistic Ambient Occlusion shadowing and shading around objects and surfaces that occlude light, with a considerably-higher degree of precision than previous AO techniques.
- Nvidia Percentage-Closer Soft Shadows add contact hardening soft shadows throughout the game, increasing image quality by a significant degree.
- Nvidia TXAA temporal anti-aliasing eliminates the distracting movement of anti-aliased lines and edges, and also eliminates other artifacts associated with anti-aliasing. Edge anti-aliasing is comparable with 8xMSAA, but at the performance cost of 4xMSAA.
- Higher-resolution textures, effects and assets make full use of the available VRAM and system RAM of PCs, adding extra detail even at 3840×2160, the next-generation 4K Gaming resolution.
- High-precision light rays increase the quality and fidelity of environmental lighting.
Check out the 4K (3840 x 2160) screenshots below (give them a click to see the full size version). There are some Full HD (1920 x 1080) shots for comparison below that.
Can you tell a difference? Let us know in the comments.
Below is Nvidia’s Assassin’s Creed 4 tech demo, showing PCSS shadows, optimised god rays, ambient lighting technology, TXAA, and other features that are unique to PC.

Ubisoft has confirmed that the fourth primary installment in the Assassin’s Creed franchise, Black Flag, will launch on PC on 22 November, Xbox One on 22 November, and PS4 on 29 November.
The current-gen release dates are 1 November for the PS3 and Xbox 360 versions, and the Wii U version is coming on 22 November 2013.
The game has been in development for nearly two years, and is spearheaded by Ubisoft Montreal, the veteran AC studio. Ubisoft has pulled out all the stops and has support from other Ubisoft studios in 6 locations across the world.
