The information in this article applies to the following configuration(s):
Elder Scrolls IV: Oblivion - aka The Chuck Patch
Radeon X1000 series CrossFire
Windows XP Professional / Home Edition
Windows XP Professional 64-bit Edition
Windows 2000 Professional
This special driver is provided to enable additional functionality for Oblivion. Specifically this driver will:
1. Permit High Dynamic Range Lighting (HDR) concurrently with Anti-Aliasing (AA) on RADEON X1000 series graphic boards
2. AFR mode for CrossFire (2 GPU’s)
Note: You will need to enable HDR and disable AA in Oblivion while enabling AA within the Catalyst Control Center. This package does not include Catalyst Control Center.
This driver is provided as a proof-of-concept and is not supported by Bethesda, 2K games or ATI Technologies.
Known issues:
1. SuperAA with CrossFire in HDR mode is not enabled. If you have SuperAA enabled you will get the quality and performance of one card as opposed to two.
2. Rendering issues with grass shadows
3. On an ATI Radeon X1600XT CrossFire configuration, the game may intermittently crash if the resolution is set higher than 1600x1200
4. On an ATI Radeon X1900 series card, the game may crash while task-switching between the desktop and game (alt-tab).
ATI Engineering is currently investigating these issues. Updates will be posted as they become available.
