Epic to Demo Unreal Engine 4 at GDC 2012

Now this is exciting news, Epic Games has announced in their GDC 2012 press release that they will be showcasing Unreal Engine 4 behind closed doors at GDC 2012. Last year at GDC 2011 we saw the Samaritan demo which was jaw dropping graphics wise but did not showcase much physics, at least destruction wise. Hopefully with Unreal Engine 4 we start to see some awesome physics or PhysX effects implemented on a larger scale. Staye tuned for more news on this and hopefully some nice preview videos like we saw last year with the Samaritan tech demo. The Game Developers Conference 2012 is this week from March 5-9th at the Moscone Center in San Fransisco.

From Epic Games Readies for Action at Game Developers Conference 2012:

Epic will also unveil a preview of its next-generation game technology, Unreal Engine 4, to select licensees, partners and prospective customers during the exhibition. Space is very limited, and appointments and non-disclosure agreements are required to see the Unreal Engine 4 presentation.

NVIDIA 295.73 WHQL Drivers Released with New PhysX System Software

NVIDIA has released new GeForce 295.73 WHQL Drivers which include PhysX 9.12.0209 System Software for improved compatibility and performance in Alice: Madness Returns and Batman: Arkham City. NVIDIA has posted an in-depth article about the improvements you can see in various games on the official Geforce website. There was also a PhysX System Software 9.12.0213 software release a few days before these drivers came out with more detailed info about the changes. You can download the new drivers here.

From the NVIDIA PhysX System Software 9.12.0213 download page:

 

  • Includes the latest PhysX runtime builds to support all released PhysX content.
  • Changes & fixed issues in this release
    • Updated SDKs for Batman Arkham City, Alice 2 and other 2.8.4 applications.
    • Fixed a bug that caused Alice 2 to crash.
  • Supports NVIDIA PhysX acceleration on all GeForce 8-series, 9-series, 100-series, 200-series, 300-series, 400-series, 500-series, and 600-series GPUs with a minimum of 256MB dedicated graphics memory.
    Note: Some applications may have higher minimum requirements.
  • Experience GPU PhysX acceleration in many games and demos, some of which are highlighted in PowerPack downloads here.
  • Supports NVIDIA PhysX acceleration on GeForce for SDK versions 2.7.1, 2.7.3, 2.7.4, 2.7.5, 2.7.6, 2.8.0, 2.8.1 and 2.8.3 (requires graphics driver v196.21 or later).
  • Supports control of your GPU PhysX configuration from the NVIDIA display driver control panel. (Requires graphics driver v196.21 or later).
  • AGEIA PhysX processors users should use and install older PhysX system software such as version 8.09.04. Note – AGEIA PPU acceleration support for 2.8.1 SDK or earlier, and Windows Vista and Windows XP only.

Intel Ivy Bridge Havok Physics Destruction and Cloth Demos

This is old now but I never got around to posting about it back during CES 2012. During the CES 2012 Intel press conference, they showed a lot of information about the upcoming Ivy Bridge Ultrabook processor including a DX11 graphics demo showing off different games that the DX11 capable Ivy Bridge processor will be capable of. They also showed several Havok Physics demos running on Ivy bridge. Intel showed the Havok Cloth Demo and the destructible bridge demo at new angles we have not seen before. The destructible bridge demo shown in the demo is very cool, it shows the presenter destroying the bridge as the train crosses and having it break into countless physics objects that get simulated in real-time. The presenter than points out how after the bridge is destroyed the CPU is still working to process each individual piece, not something that happens with the scripted destruction nonsense we see in many games today. This is another demo that I wish would be released to play around with. Check out the videos below.

New Apex PhysX Art Gallery Destruction Video

The NvidiaApexDeveloper YouTube page has uploaded a new video from the Art Gallery demo showing off some awesome Apex physics and destruction. Check it out below. For more footage of this demo in action check out the original Art Gallery Destruction Demo in UE3 using APEX Destruction with GRB’s video. Hopefully this demo becomes available for download soon, maybe with the release of Kepler? I still don’t know why NVIDIA does not release these cools demos for people to play with.

From the official NVIDIA Apex Destruction page:

Everything in the Art Gallery demo is destructible, the drywalls, beams, ceilings even the wooden floors. The demo is using GPU rigid bodies (GRBs) to ensure that up to 10,000 rigid bodies can be simulated at the same time, which enables a massive degree of destruction unseen before in a game. This demo was was the work of one artist and was done in less than two weeks. It provides a excellent example of how APEX authoring tools allows artists to quickly generate destructible worlds.
