SHEFFIELD, UK (26 July 2010) - Lightworks, the world's leading supplier of rendering solutions for
developers of advanced 3D computer graphics software, will today reveal new solutions which leverage
the latest GPU ray tracing acceleration technology from NVIDIA, the world leader in visual computing
technologies and the inventor of the GPU.

A new OptiX based Lightworks product is at the core of these new solutions which will be previewed
at this year’s Siggraph Exhibition in Los Angeles. They use the power of the NVIDIA GPU and are
built on NVIDIA’s CUDA parallel compute architecture which not only enhances the interactivity of
the user experience but also provides significant performance improvements for Lightworks customers.
Lightworks are showing this new OptiX based product working with the latest Tesla graphics cards on
the Lightworks booth #225 at Siggraph 2010 and on the Rendering Pod on NVIDIA’s booth #717.

Dave Hutchinson, Product Director at Lightworks, commented “Using the OptiX engine in both our
Lightworks Artisan and Lightworks Author products gives us the ability to handle larger and larger
models and to generate compelling, high quality renders. We’re really impressed with the
interactivity seen with large models, as well as the immediate response to changes in material and
lighting previews that we are generating.”

“The tremendous acceleration Lightworks is getting from OptiX is great news for their many end
users, and demonstrates how their rendering expertise can quickly leverage NVIDIA’s CUDA platform
and GPU performance for optimal results” said Phillip Miller, Director of Software Product
Management for Professional Solutions at NVIDIA. He added, “Lightworks recognizes the importance of
continually introducing new functionality and performance into their products and we know that the
features Lightworks is accelerating with OptiX will dramatically improve what’s possible for their
customers.”

Bob Mayer, COO of IMSI Design, remarked “Lightworks has some great technologies coming out this Fall
and we’re particularly excited about the new OptiX product and are looking forward to being able to
integrate it into future versions of TurboCAD.”

A pre-release of these new Lightworks solutions will be available to Lightworks customers in October
and a full product release is planned for December 2010.
