AMD had released an updated hotfix to its ATI Catalyst 8.10 drivers the other day, with hotfix 71310. It succeeded hotfix 70517 for the said version of Catalyst. Hotfixes specific to certain games, are intended to selectively improve hardware performance and/or visual quality. When AMD released the older hotfix for version 8.10 of Catalyst, it aimed to improve performance in general. It was later found by keen observers, that the hotfix manipulated with visual elements of the game in an attempt to gain performance. A popular example of this, was noted in the "lost rocks" issue in Far Cry 2, where the hotfix 70517 caused the texture and/or geometric loss of certain rocks along a track from a scene, presumably reducing load on the graphics processor(s).

With hotfix 71310 issued yesterday, AMD seems to have fixed the issue. Expreview put the hotfix to test, where it was found that the "lost rocks" issue was fixed. The larger issue was of the driver interfering with visual elements the game has to offer. The fix however, came at the expense of performance. Expreview used a test-bed consisting of Core 2 Extreme QX9650 CPU, ATI Radeon HD 4870 graphics, 2x 1 GB of DDR3 1066 MHz memory, all seated on an ASUS Striker II Extreme motherboard, running Windows Vista 32-bit operating system. The testers used Driver Sweeper to make sure a new variant of the driver installed on a purged environment. Testing Far Cry 2 revealed that the issue was addressed, but at a performance loss. The frame-rate dropped from 48.12 fps to 43.20, which is roughly a 10% loss in frame-rate.
