В драйверах Catalyst 4.8 были добавлены следующие возможности: Geometry Instancing: эта возможность будет оказывать заметное влияние, когда в игре используется множество объектов с одинаковой геометрией. Geometry Instancing позволяет VPU создавать множественные объекты, с одинаковой геометрической моделью. Это позволит добиться повышения скорость рендеринга сцен с большим количеством листьев или травы. VPU Recover Enhancement: улучшена работа VPU Recover. EIA 861B Timing Specification: начиная с этого выпуска в драйверах будет представлена EIA 861B Timing Specification для DVI-телевизоров. В Catalyst 4.8 повышено быстродействие Direct3D драйверов в различных приложениях (в том числе, в 3DMark2001, Aquamark 3, Comanche4, Dungeon Siege и Unreal Tournament 2003/2004). Типичное улучшение составляет от одного до пяти процентов. Повышена эффективность OpenGL драйверов. Старые игры такие как Quake III Arena и Wolfenstein — Enemy Territory показывают незначительные улучшения (на 1-2 процента) на низких разрешениях. Фреймрейт Call of Duty вырос приблизительно на 4%, а в Doom3 прирост составляет аж до 12%. Также были разрешены некоторые проблемы в некоторых играх и приложениях (3D Mark03, Beyond Divinity, High Heat Baseball 2003, Madden NFL 2003, Need for Speed Underground, Splinter Cell Pandora Tomorrow, Thief 3, Unreal Tournament 2004).

New features include: Geometry Instancing VPU Recover Enhancement EIA 861B Timing Specification Geometry Instancing This release of CATALYST introduces the support of Geometry Instancing. This new feature provides assistance when a game has to render many objects where the geometry is highly similar. Geometry Instancing allows the VPU to create multiple objects from a single geometric model, rather than passing an entire new model for each item on the screen. This increases the rendering speed of images such as leaves, or grass. VPU Recover Enhancement VPU Recover has been improved in this release of CATALYST. In most cases, VPU Recover will fully recover instead of switching to software rendering mode. This enhancement is supported under the Windows XP operating system. EIA 861B Timing Specification This release of CATALYST™ introduces EIA 861B Timing Specification for DVI based televisions. The RADEON™ Software Release version 8.04 will support 256 byte E-EDID and will decode CEA timing extensions. Further, it will retrieve DTV timing information. When the driver detects EIA 861B timings in E-EDID that the controller cannot handle, it will replace the EDID detail timing with adjusted timings suitable to our controller. The modes will be added as EDID detailed timing. Common modes that are supported include: 640 x 480p at 60 Hz and 25.2 MHz pclk 720 x 480p at 59.94 Hz and 27.0 MHz pclk 720 x 576p at 50 Hz and 27.0 MHz pclk 1280 x 720p at 60 Hz and 74.25 MHz pclk 1280 x 720p at 50 Hz and 74.25 MHz pclk 1920 x 1080i at 60 Hz and 74.25 MHz pclk 1920 x 1080i at 50 Hz and 74.25 MHz pclk 1920 x 1080p at 60 Hz and 148.5 MHz pclk 1920 x 1080p at 50 Hz and 148.5 MHz pclk This feature will be supported under the Windows XP and Windows 2000 operating systems. Performance Improvements As with most CATALYST™ releases performance has increased in various situations. The following performance gains are noticed: Direct3D driver efficiency has improved considerably. Significant performance gains are noted in multiple "CPU-bound" cases, including 3DMark2001, Aquamark 3, Comanche4, Dungeon Siege, and Unreal Tournament 2003 and 2004. Typical improvements are in the 1-5% range. OpenGL driver efficiency is also improved. Older OpenGL games such as Quake III Arena and Wolfenstein - Enemy Territory show small improvement (1-2%) at low resolutions. Call of Duty framerates are up approximately 4%. Doom3 improves considerably more (as much as 12% on some product configurations) as a result of the same software efficiency improvements. Issues Resolved in CATALYST™ Version 4.8 The following section provides a summary of the issues that have been resolved in the latest release of CATALYST™ 4.8.
