DirectX 11 Details Emerge

Categories: Microsoft DirectX, Programming   Tags: , , , , , , ,

Similar to DirectX 10, DirectX 11 will be available only on Windows Vista and future versions of Microsoft’s operating system. DirectX 11 will add new compute shader technology that Microsoft says will allow GPUs to be used “for more than just 3D graphics,” allowing developers to utilize video cards as parallel processors.

DirectX 11 will support tessellation, a feature which can potentially assist developers in making models appear smoother when seen up close. Multi-threaded resource handling is also incorporated, making it easier for games to utilize multi-core processors in a user’s machine.

GPU PhysX Doesn’t get you to 3DMark Vantage Hall of Fame Anymore

Be the first to comment - What do you think?  Posted by JeGX - at 10:22

Categories: Benchmarks, Graphics Cards, NVIDIA PhysX   Tags: , , , ,

Futuremark has now decided to update its Hall of Fame to exclude all results using PhysX on a GPU, simply because this was not how they intended it to work.

With NVIDIA releasing their GeForce PhysX drivers, users of the PhysX accelerating GeForce cards were at an advantage over their Radeon counterparts, reason being that in a certain CPU test routine of the 3DMark Vantage benchmark, the physics processing abilities of the computer are tested, and since the physics API used happens to be PhysX, users of GeForce get higher scores despite not having a physics processor device such as an Ageia PhysX card. This differs from a real-life scenario where a GeForce accelerator does both graphics and physics and the overhead of physics processing affects the graphics processing abilities.

Gamestudio/A7, the easy all-in-the-box game development system, announces the release of version 7.10.

Gamestudio homepage: www.3dgamestudio.com

Gamestudio is not a game engine, not a game editor, and not a game programming language. It’s all of them together. It contains all necessary tools for creating commercial-quality 3D or 2D games or realtime graphics applications right out of the box. It comes with a state-of-the-art 3D and 2D game engine, a level editor, a model and terrain editor, the lite-C script language with compiler, editor, and debugger, as well as thousands of ready-to-use elements, such as models, level prefabs or textures.

AMD supports PhysX on Radeon

Be the first to comment - What do you think?  Posted by JeGX - at 10:19

Categories: NVIDIA PhysX   Tags: ,

It seems AMD/ATI really want to support the porting of PhysX on Radeon:

“We think that it is great that people continue to use our products in creative ways.”

When we’ve spoken to AMD it doesn’t seem like that AMD doesn’t want this to happen, on the opposite, anything that could add more value to the already affordable Radeon HD 4800 series is a plus.

InfraRed Photo Shows which Part of Your HD 4870 is Hot While Running FurMark

5 comments - What do you think?  Posted by JeGX - 2008/07/18 at 17:23

Categories: Benchmarks   Tags: , , , , ,

German Radeon user Tiesie have posted some Infra-red photo of his/her HD 4870 with Arctic Cooling Accelero S1. The sticker part is hot and keeping the reference red cooler base is no help for cooling. All these shots have been taken after 10~20min of FurMark.

I wonder if Tiesie has used FurMark in Xtreme Burning mode (currently command line but soon in the startup dialog box) or in standard mode…
