If you have an ATI Radeon 8500 retail AGP card and you play Tom Clancy's Raven Shield (with or w/out the Athena Sword mod) you might want to consider staying at 10.3.6. The ATI drivers suck. Significant frame tearing occurs only after the upgrade, esp. on maps like Peaks w/ the smoke grenades and thermal sights. Installing or removing ATI Displays makes no difference, at least not w/ the ATI displays version 4.4.2f5 (latest as of 1/05/05). But that has been there since 11/04, 1 mo. before 10.3.7 w/out issue. Vertical sync on or off does not effect Peaks, but does affect the custom U.W.A. map. Now if I can only figure out a way to extract the ATI .kexts and drivers from 10.3.6 pkg.... either that or I guess I'm going to try the version 224 ROM since it's included w/ 227 in the Oct 2004 universal ROM update. But again, ROM version 227 has also been present since way before the 12/04 intro of 10.3.7, and before 11/04 intro of ATI displays 4.4.2f5. Ghost Recon and Splinter Cell seem to work fine.
