YouTube user ThatsPie has made a pretty cool video showing off the PhysX in Torque 3D. This is a completely new video not from the Torque 3D demos we have seen before. Check it out below. If you are interested in the Torque 3D engine and its PhysX, be sure to check out our Torque 3D Pacific Physics (PhysX) Demo and Video from the Pacific Demo available on the Torque 3D website.

Ever since we saw the Glowball PhysX demo and the Floating Castle Physics Demo running on Tegra 3 powered tablets we have been pretty excited about physics on Tegra powered devices. Back in November NVIDIA announced the released of their new Quad-Core mobile Tegra 3 chip that uses “four CPU cores and its new GeForce GPU to render an interactive environment with real-time dynamic lighting, real-time physics, fluid gameplay and more.” Now instead of another demo, MADFINGER Games, the developer of Shadowgun has made a Tegra 3-optimized version of Shadowgun with some cool physics/PhysX effects that can take advantage of the quad core Tegra chip and it’s GPU. Check out the video below. As you can see from the video, the Tegra 3-optimized version of Shadowgun has some cool cloth, water/fluid, ragdoll and destruction physics effects that really add to the game and its environment.

From Shadowgun Flexes Tegra 3 Quad-Core Muscles:

The popular Android game Shadowgun has been enhanced to take advantage of the Tegra 3 quad-core mobile processor. This demo shows Shadowgun’s graphics performance when played on Tegra 3 devices.

The Tegra 3-optimized version of Shadowgun features console-quality water, enhanced rag-doll physics, particle effects, enhanced shaders and dynamic textures. These are only possible using Tegra 3’s multi-core capabilities, and they make for a truly immersive and realistic gaming experience.

Metro Last Light PC Developer talks about GPU-PhysX

PC Games Hardware has done a really nice and in-depth technical interview about the upcoming Metro Last Light. PC Games Hardware spoke to Oles Shishkovtsov, CTO at 4A Games to talk about the different technology that will be implemented into the game and most interesting and exciting to us the GPU PhysX support! When asked if we can expect some PhysX improvements from Metro: 2033 Oles replies with “Yes, you can expect a lot of improvements, especially in destruction and debris.” You can read the entire interview here.

For more information about Metro Last Light and PhysX check out the posts we did recently, Metro: Last Light Interview Talks PhysX and Metro: Last Light Gameplay Video Shows Amazing PhysX effects for some in-game footage where you can see these new PhysX effects and features in action.

From PC Games Hardware Metro Last Light PC aims for the technology throne: Developer talks about DirectX 11, Tessellation, GPU-Physx & Co:

PC Games Hardware: You keep the support for GPU PhysX in Metro Last Light. If so can we expect some improvements or enhancements compared to Metro 2033 (e.g. soft bodies, debris, and destructible environments)? What graphics card do you recommend for maxed details in Full HD with Antialiasing? An upcoming Nvidia Kepler-based Geforce for example?

Oles Shishkovtsov: Yes, you can expect a lot of improvements, especially in destruction and debris. The upcoming Geforce cards will be fully supported.

PC Games Hardware: When benchmarking Metro 2033 we found out that the engine utilized more than four cores of multicore CPUs if we were using the advanced PhysX effects on CPU, so you are utilizing Nvidias PhysX SDK 3.x? Will all the advanced PhysX effects only be available in PC version?

Oles Shishkovtsov: That’s the common misconception that PhysX 2.X cannot be multithreaded. Actually it is internally designed to be multithreaded! The only thing – it takes some programmer time to enable that multi-threading (actually task generation), mostly to integrate with engine task-model and ensure proper load-balancing. So, 2033 used PhysX 2.8.3, and Last Light uses similar, a slightly modified version at the time of writing. And yes, advanced PhysX effects will be available only on PC.

GenL has released his Hybrid PhysX mod version 1.05ff for GeForce 285.xx drivers and PhysX System Software 9.11.0621. If you use an AMD/ATI graphics card but want to have GPU PhysX support for the latest games that support it you can use this mod to use a second cheap NVIDIA card to calculate the PhysX while the ATI/AMD card will be the main graphics renderer. Check out the official Hybrid PhysX mod thread over at the ngohq.com forums for more information. To see how this works check out the Sapphire ATI Radeon 5870 + 9800GT Hybrid PhysX setup Video and the GenL’s Hybrid PhysX Mod Running ATI HD4870 X2 EVGA GeForce 8800 GTX( Dedicated PhysX Card) that we posted about before.

From the NGOHQ.com Hybrid PhysX mod v1.03 / v1.05ff page:

1.05ff – 26/10/2011:
- added support for fixing new limitations introduced in 285.xx drivers and PhysX System Software 9.11.0621
- mod will now delete all application 3D settings profiles from NVIDIA Control Panel (prevents problems with known PhysX games)
- updated old patterns

* INSTALLATION STEPS (Windows 7):
1. Install the needed GeForce driver 256 package. Update PhysX SS (only 9.10.0223 or later) if needed.
2. Use the mod to patch all needed files and registry values automatically.
3. [optional] Use command line files to set a desired configuration.

* INSTALLATION STEPS (Windows XP/2003):
1. Install the needed GeForce driver 256 package. Update PhysX SS (only 9.10.0223 or later) if needed.
2. Use the mod to patch all needed files and registry values automatically.
3. Extend the display assigned to NVIDIA GPU. Or make sure it is extended already.
4. [optional] Use command line files to set a desired configuration.

* NOTES:
1. If you update PhysX System Software after using the mod, you should use it again to patch the updated PhysX files.
2. It is safe to use the mod several times – all needed files will be patched only once.
3. If you still have problems with fake displays and desktop extension, try to delete a fake display and create it again.
4. To let the mod correctly patch all needed files on x64 versions of Windows XP/2003, install KB942589 hotfix first.
