Next week, Ratchet & Clank: Rift Apart is launching on PC! Many of you have asked for details about the technologies used and system requirements. Today we are answering those questions, and on top of that, we have some exciting new feature announcements. To ensure a smooth dimension-hopping experience, our team implemented DirectStorage 1.2 in Ratchet & Clank: Rift Apart on PC, including GPU decompression.

Richard van der Laan, Senior Lead Programmer at Nixxes Software, explains: "To enable quick loading and instant transition between dimensions, the game needs to be able to load assets quickly. DirectStorage ensures quick loading times, and GPU decompression is used at high graphics settings to stream assets in the background while playing. Traditionally, this decompression is handled by the CPU, but at a certain point, there is an advantage to letting the GPU handle this, as this enables a higher bandwidth for streaming assets from storage to the graphics card. We use this to quickly load high-quality textures and environments with a high level of detail."

The latest beta drivers and the first in the 290 series have been released by NVIDIA today, supporting all graphics cards since the venerable 6-series. Their main new feature are official support for enabling ambient occlusion settings in the control panel separately for specific games and enabling NVIDIA Surround on the new X79 SLI-certified motherboards. Ambient occlusion (AO) is settable for uber-popular games The Elder Scrolls V: Skyrim and Call of Duty: Modern Warfare 3. So, what does AO do? We'll let Andrew Burns of NVIDIA explain:

If you're unfamiliar with Ambient Occlusion, it is most easily described as a way to make in-game shadowing more realistic, and therefore better.

What he doesn't say of course, is how it kills your frame rate, especially on lower end hardware. Anyway, there's all the usual goodies in this release: 3D Vision game profiles for games such as MW3, Diablo 3 & LEGO Harry Potter: Years 5-7 (yes really). There's a HD audio update and nine fixes too, including one for random flickering of the Windows boot logo as it's loading or fading away and a fix for the mouse cursor flickering and shaking in games such as Crysis 2 & Deus Ex when SLI is enabled when using 3DTV Play. The NVIDIA product release page is here and they have a snazzy-looking driver selector here. The release notes follow.
