Quake Wars goes Larrabee?

Quake Wars Ray Tracing: More screenshots and details released

There are a HD video, new screenshots and additional details of the ray tracing version of Quake Wars available.

It is common knowledge that Intel developed a Ray Tracing version of Quake Wars. PC Games Hardware reported about a video showing ray traced Quake Wars in early June already. Intel employee Daniel Pohl has updated the Quake Wars Raytraced website so we decided to deal with the topic again.

Quake Wars: Ray Traced is, according to the website, a project of an Intel research group. The real-time ray tracer in use is optimized for current multi-core x86 CPUs. The long-run target is to establish real-time ray tracing as an alternative rendering path besides rasterization. Many-core architectures like Larrabee and the Larrabee successor are explicitly named.

The main features of Quake Wars Ray Traced are:
- Water with reflections and refractions
- Realistic glass shaders
- Accurate shadows
- Camera portal effects
- Displaying the MegaTexture
- Collision detection using ray tracing
A demo displayed in 2008 ran with 15 to 20 fps at 1,280 x 720 on a Caneland system with four Tigerton-Quad-Cores (so all in all 16 cores), which were clocked to 2.93 GHz. An enhanced demo, which was displayed in August 2008, already ran with 20 to 35 fps. The system back then consisted of four Dunnington CPUs with six cores each - 24 cores all in all. According to Daniel Pohl the performance is practically scaling linear with any additional core.

In our gallery you can find new screenshots of Quake Wars which have been made on a real-time ray tracing basis. At this point it must be pointed out that the screenshots were smoothened with Super Sampling, which hadn't been the case during the live demo.

All on paper. We shall see real time results when it arrives...

The only thing that got my attention is how the shadow works, and even then its not such a huge leap.

Games are suffering from low FPS as it is without some more Reflections and Refractions (I thought i'll be sick how many times that guy said those words ). Thank you but i'm good with Duke Nukem type of mirrors reflections

And what exactly the portal effect does? I thought they already done all that in Prey...
