AMD Radeon HD 6900 Tech Demo Featuring GPU Physics

[caveman-jim]

AMD Developer Central is now hosting a new tech demo, featuring Bullet Physics and extensive DirectX 11 features.

The HK-2207 real-time demo features a number of post processing effects (depth-of-field, lens flare, ghosting, aerial perspective/atmospheric, LUT, emissive and reflection) provided as an easy approach for developers and artists to adopt Microsoft® DirectX® 11 programming. This demo also uses a current trend in game engines utilizing deferred lighting and deferred shading allowing many more lights and rapid prototyping. A newly developed GPU accelerated physics particle system is introduced utilizing DX11 DirectCompute. Bullet Physics is used with a new fracture/destruction approach that also features procedurally generated unique debris leveraging DX11 tessellation.

The HK2207 demo requires Windows Vista® or above operating system, a Radeon™ HD 6900 Series graphics processor and associated Catalyst™ software, a dual- or quad-core CPU, and 2GB of RAM.

I tried it on my rig due to a suspision that technically it should work since it is DX and openCL coded and by jove, it did. Not very impressed with its presentation mind you

[Sasquach]

Yeha its kind of...bleh looking.

[zebra 204]

Tech demo, eh?

[Mystik]

screenshots look.. extremely lacking.

what ever happened to ruby?
they could've done something similar in "Ruby's day at the beach."
complete with gpu physics.

Wait, I played this game back in 1998, back when it was still called Shogo. I would have thought Lithtech would look better then that by now

Just kidding

Does look like it though. Shogo may have looked better in some places. Not that Nvidia's recent attempt at tech demos are any better, they had to get a third party to make the better one for GTX 500 series, Stone Giant. The one they made themselves is crap. Endless City is worse looking then this is, WAY worse.

The GTX 400 demos look better then the 500 demos! Both Nvidia and AMD are cheaping out this generation for demos.

Actually the demo reminds me more of the game Slave Zero than Shago

The water actually looks worse then the 3Dmark 2001 SE shader test. I didn't think water would ever look that terrible in anything else.

While initially "unimpressive" the following readme has significant options

The HK-2207 real-time demo features a number of post processing effects (depth-of-field, lens flare, ghosting, aerial perspective/atmospheric, LUT, emissive and reflection) provided as an easy approach for developers and artists to adopt Microsoft® DirectX® 11 programming.

A newly developed GPU accelerated physics particle system is introduced utilizing DX11 DirectCompute. Bullet Physics is used with a new fracture/destruction approach that also features procedurally generated unique debris leveraging DX11 tessellation.

Deferred shading does not permit the use of traditional anti-aliasing. AMD introduced a new Morphological AA based on DirectCompute in the latest Cayman drivers that can only currently be enabled via Catalyst Control Center as described below.

************************************************* *
* Morphological Anti-Aliasing is not enabled by
* default.
*
* To enable this feature and enhance the
* appearance of this demo, follow the instructions
* below.
*
*************************************************

Step 1. Open the ATI Catalyst(TM) Control Center and

Either: Right-click on an open area of the desktop, and select Catalyst Control Center from the pop-up menu;

Or: Click Start > Control Panel > Display >
Change Display Settings > Advanced; Choose the Catalyst Control Center tab, and select the ATI Catalyst Control Center button.

Step 2. In the upper-left corner select
Graphics > 3D > AA.

Step 3. Check the "Morphological filtering" checkbox

Step 4. Click the "OK" button.

LOL, it also runs on GTX 580.

Why wouldn't it? It uses open standards and non-proprietary technologies...

Remove the bolded video card named above and replace with "Any Direct X 11 supporting video card".

And it could have been worse. They could have locked it to a driver detect like a certain other company does.

Your talking about Nvidia right?... It has to be Nvidia 'cause thats what they do. Yea it's Nvidia.

Matrox did it also, remember the fish tech demo

[noko]

Is there a benchmark mode to it? I wonder who can do bullet physics faster, AMD or Nvidia?

iirc that was because at the time (G400?) was the 1st and (iirc) only to have support for Environment Mapped Bump Mapping, it was not a matter of locking competition out.

edit oh you're talking about the Matrox Parhelia Reef demo, didn't it use PS 1.4 and at the time only the R8500 was able to run it (although very slowly) ?

Negative. Parhelia launched in 2002, Geforce 4 came out around that point. GF 4 Ti supported SM 2.0/2.0A and could eat Parhelia alive in EMBM performance. I loved the Ti 4400, amazingly tweakable card.

Nope GF4 Ti could only do PS 1.3 The First chip that supported SM 2.0 was R300 (Radeon 9700 Pro).

However it seems that Parhelia also wasn't SM 1.4 compliant (though I also remembered incorrectly that it was).

Oops, shows trusting the first page of Google isn't always advisable, lol! I guess we both got bit on that one

You were only able to run that reef demo with a 3rd party patch, If i remembered correctly you couldn't run it directly.

You do remember correctly. It could be run on any D3D supporting card using a wrapper package. I still have all that on one of my ancient archive disks around here somewhere.
