46
graphics card. The result is a complete frame rendered at up to twice
the performance of a single graphics card.
8 How are the graphics cards connected on a CrossFire
™
system?
The two cards are connected by an external cable. The cable is
attached from the Slave graphics card’s DVI-I connection to the
CrossFire
™
Edition’s CrossFire
™
connection, which is used to convey
information from the Slave graphics card to the Master graphics card
and transmit the combined signal to a display device.
9 Which games/applications work with CrossFire
™
?
CrossFire
™
works with all full-screen 3D games and applications.
Catalyst
™
A.I. is enabled by default in the Catalyst
™
Control Center
software. This automatically selects the optimal rendering mode for
the application.
10 Is a driver profile required to make CrossFire
™
work?
No. CrossFire
™
is enabled by default for all full-screen 3D games and
applications.
11 What happens if you pair a two CrossFire
™
Edition graphics
cards with different architectures?
In this scenario both graphics cards will operate at the speed of the
slower graphics cards while in CrossFire
™
mode. You will be required
to restart your computer for this matching to take place.
12 What happens if the CrossFire
™
Edition graphics card and the
CrossFire
™
Ready graphics card have different clock speeds?
Both cards will continue to operate at their individual clock speeds;
neither card is “stepped down.” The compositing engine on the
CrossFire
™
Edition card merges the resulting images independent of
the clock speed on either graphics card.
13 On what basis are different rendering modes chosen?
When Catalyst
™
A.I. is enabled in Catalyst
™
Control Center, it
determines the optimal rendering mode to use, based on the
application or game being used. The default rendering mode is
dependant on both the hardware configuration and the application
being run.
14 What type of performance improvement is expected?
Performance enhancements experienced on a CrossFire
™
system
depend on the application or game being used. Performance
improvements can be increased up to 100%.
