AMD has released a new set of Catalyst graphics drivers for its Radeon graphics cards. The new 8.3 drivers bring several new features, including CrossFire X support, as well as significant speed improvements in a number of titles. Thanks to CrossFire X, users can slap as many as four Radeon HD 3850 or Radeon HD 3870 graphics cards (or two Radeon HD 3870 X2s) into a single system and harness their combined graphics processing power in games. We should have some benchmarks of CrossFire X for you very soon. Stay tuned.
Not everyone can afford to buy three of four graphics cards, of course, but there are additional features and performance improvements built into these latest drivers that should make other users happy. In its release notes for the drivers, AMD claims the following performance gains:
Call of Juarez: Performance scores increased up to 20% on ATI CrossFireX™ configured systems containing an ATI Radeon™ HD38x0 series of product Company of Heroes (DirectX 10): Performance scores increased up to 17% (especially at lower resolutions), on ATI Radeon™ HD38x0 products Crysis (DirectX 10): Performance scores increased up to 15% on all supported ATI Radeon™ products Lost Planet (DirectX 9): Performance scores increased up to 36% across all supported ATI Radeon™ products and in ATI CrossFireX™ configured systems Shadermark 2.1: Performance scores increased up to 35% across all supported Radeon™ products and in ATI CrossFireX™ configured systems Unreal Tournament 2004: Performance scores increased up to 10% on ATI CrossFireX™ configured system containing an ATI Radeon™ HD2400, HD2600, or HD3400 series of products
In addition to the above, users who install the new drivers will find:
In addition to this cornucopia of new features, the Catalyst 8.3 release also fixes bugs in Elder Scrolls IV: Oblivion, Enemy Territory: Quake Wars, Guitar Hero 3, Halo 2, Resident Evil 4, Splinter Cell Double Agent, World in Conflict, and World of Warcraft.
