Press release:  VIDEOLOGIC VIVID!XS(tm) HARDCORE GRAPHICS ACCELERATOR

Date : 2001-03-22

VideoLogic Systems - a division of Imagination Technologies - has today
announced the VideoLogic Vivid!XS, its first performance graphics add-in
card based on the new PowerVR KYRO II(tm) graphics processor. The 32MB
Vivid!XS will ship in April 2001, with a RRP price of £85 ex. VAT.

The VideoLogic Vivid!XS is a fully featured, high performance graphics card
for gamers at an affordable price with blazing games performance, future
proof technology, full support for industry-standard game APIs like
Microsoft® Direct3D(tm) and OpenGL(tm), a fast 128-bit 2D engine, hardware
video playback, TV output and DVD decode acceleration.

Kevin Dale, president, VideoLogic Systems, says: "Vivid!XS is a
high-performance successor to the award winning Vivid! graphics board. For
high-intensity gaming Vivid!XS provides segment leading performance at a
very affordable cost with an enormous effective fill rate, intense scene
complexity and all with the dazzling visual quality of full 32-bit
rendering."

Vivid!XS features stunning 3D effects including environment mapped bump
mapping, 8-layer multi-texturing, DXTC texture compression, pixel-perfect
full scene anti-aliasing (FSAA), superior colour precision via 32-bit
Internal True Colour(tm), alpha blending, advanced texture sampling and
filtering modes and specular highlights.

Vivid!XS\' PowerVR technology thrives on complex 3D games - its effective
fillrate actually increasing as the games gets more complex, drawing
increasingly \'deep\' and complete 3D worlds. At an average image depth
complexity of four (typical of new 3D games) Vivid!XS provides an effective
fill rate of 1.4gigapixels per second. Vivid!XS includes 32mb of high
performance SDRAM memory and its PowerVR KYRO II graphics processor has
support for resolutions up to 2048 x 1536, 175MHz clock-speed, 2X AGP
support, and over 12 million fully featured polygons per second.

Vivid!XS is based on the KYRO II processor from STMicroelectronics and
designed by PowerVR Technologies (a division of Imagination Technologies).

Tile Based Rendering



VideoLogic\'s Vivid!XS utilizes patented PowerVR Tile Based Rendering to
avoid memory bottlenecks and deliver state-of-the-art image quality and
stunning 3D graphics performance, with crisp 2D graphics, studio quality
video playback, and DVD decode support.

Hidden surface removal identifies surfaces that are not visible in the final
scene and discards them before the scene is textured, lit and shaded. The
resulting deferred texturing eliminates much of the redundant processing
performed by conventional 3D systems. Vivid!XS\' combination of tile-based
rendering and deferred texturing makes extremely efficient use of memory
bandwidth, typically giving three times the performance of conventional 3D
accelerators with comparable memory bandwidth.

TV output


Vivid!XS can connect to any television, VCR or projector to display games
and DVD movies in full-screen format or tape game sequences and videos for
digital editing.

Full Scene Anti-Aliasing (FSAA)


Vivid!XS can implement both 2X and 4X high quality pixel-perfect Full Scene
Anti-Aliasing. Full Scene Anti-Aliasing delivers a significant improvement
in visual quality by using a high data resolution image and scaling that
image to the display resolution. The result is smoother, more realistic
graphics at low resolutions.

Superior Colour Precision - 32-bit Internal True Colour(tm)
All of Vivid!XS\' pixel operations are rendered on chip at full 32-bit
Internal True Colour resolution, maintaining the best possible image quality
irrespective of the number of image layers or frame buffer bit depth. When
operating in 16bpp frame buffer, Vivid!XS avoids the colour banding or
grainy effects seen on traditional 3D hardware to give best game performance
without sacrificing visual quality. Internal True Colour also saves memory
bandwidth whatever the colour depth, thus enabling Vivid!XS to provide
class-leading performance in 32bpp modes.

Realistic Environments Using Unique 8-Layer Multitexturing
Vivid!XS fully supports 8-layer multitexturing, significantly improving on
the dual or triple texturing capabilities of traditional accelerators. With
its support of multiple texture layers, Vivid!XS allows more detailed
backgrounds, realistically lit models, and more plausible environments to be
rendered. When compared with traditional accelerators, Vivid!XS\' 8-layer
multitexturing results in significant performance and quality improvements.

Direct3D Environment Mapped Bump Mapping


Vivid!XS provides efficient Direct3D Environment Mapped Bump Mapping, which
adds significant realism to 3D rendered scenes by allowing the developer to
create the illusion of depth on a surface. Vivid! XS\' Environment Mapped
Bump Mapping uses per pixel operations to represent detail on much larger
polygons. As Vivid!XS\' Environment Mapped Bump Mapping is fully Direct3D
compliant, developers are able to use it to create a wide range of surface
texturing effects including making metal, plastic, rubber, or other objects
look real.

Future Proofing


As the depth complexity of games continues to increase other graphics cards
bought today will begin to slow down, delivering much lower performance
scores on future games than they do on current software. Because Vivid!XS\'
PowerVR technology is not slowed down by increasing depth complexity
Vivid!XS will still provide excellent performance on the games of tomorrow.

Compatibility and Support


Vivid!XS fully meets the requirements of PC 99A. Vivid!XS ships with
high-performance drivers for Microsoft Windows 95/98, Windows Me, Windows NT
4.0 and Windows 2000 operating systems and accelerated video and 3D drivers
for DirectDraw, Direct3D and OpenGL (No Direct3D in NT 4.0).

PowerVR Tools provide control panel utilities for screen resize and
adjustment, refresh rate selection, gamma correction, TV control, 3D feature
selection and optimisation, customer support and diagnostics information.

The Vivid!XS retail package also includes the latest version of InterVideo\'s
award-winning, fully-featured WinDVD 2000 software for high-quality software
DVD playback.

Other Vivid!XS features include a fast 128-bit 2D engine, hardware video
playback and DVD decode assistance, AGP 2.0 Interface supporting AGP 1x and
2x with SBA for host based textures, a 128-bit SDRAM interface and
integrated palette DAC.

Vivid!XS is backed up by the very best in free lifetime support including:
technical support hotlines; Internet based support; and a five year hardware
warranty.
