ATI driver enables HDR with AA in Oblivion

— 7:13 PM on April 6, 2006

ATI has released a driver update that allows users to enable both high dynamic range (HDR) lighting and antialiasing in The Elder Scrolls 4: Oblivion. Dubbed the "Chuck" patch, after its creator, it requires an ATI Radeon X1000 series graphics card and also allows CrossFire's alternate-frame rendering (AFR) mode to be used in the game. Chuck ran some preliminary benchmarks, which were kindly provided to us by Terry Makedon, ATI's manager of Radeon software and video marketing. The benchmarks were run at 1600x1200 with HDR on, and show a jump of 25 to 40.5 frames per second from CrossFire's AFR mode with 6x FSAA enabled, and an average of 33.6 to 59.6 frames per second without antialiasing. While the tests were apparently run on an AMD Athlon 64 FX-57 machine, there is no indication of which video cards were used—it's likely Chuck went for a pair of ATI's X1900 XTXs, though, considering how demanding Oblivion is.
