CrossFire™
CrossFire™ is a multi-GPU performance gaming platform, using
CrossFire™-ready motherboards and CrossFire™-compatible graphics
cards.
CrossFire™ works with all 3D games and applications. If ATI Catalyst™
A.I. is enabled in the ATI Catalyst™ Control Center software, the optimal
rendering mode available for the application is automatically selected.
Performance enhancements experienced on a CrossFire™ system depend
on the application or game being used. Performance improvement of up to
100% have been recorded. The latest graphics-intensive programs will
generally see over 80% performance improvement at high resolutions and
high image-quality modes.
