737-21960: Beta 6.3 Catalyst for Elder Scrolls IV: Oblivion - aka The Chuck Patch

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
This special driver is provided to enable additional functionality for Oblivion. Specifically this driver will:

1. Permit High Dynamic Lighting (HDR) concurrently with Anti-Aliasing (AA)
2. AFR mode for CrossFire (2 GPU’s)

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 SupperAA 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 they set resolution is 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.

ATI support and download driver Window Xp/2K & 64-bits

Using both HDR and AA is really a performance killer

You need something better from a X1900XTX to play these game with HDR+AA and maximum graphic settings
