The Elder Scrolls IV: Oblivion Performance Tweaks

If you're still trying to get more performance out of the PC version of The Elder Scrolls IV: Oblivion, then you might want to take a look at GameSpot's new hardware performance guide or ATI's latest beta driver. This new driver actually allows you to enable High Dynamic Range Lighting (HDR) and Anti Aliasing (AA) in the game at the same time, as long as you have a supported ATI video card. Check it out:
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 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 driver is provided as a proof-of-concept and is not supported by Bethesda, 2K games or ATI Technologies.
