NVIDIA today released the Unreal Tournament 3 NVIDIA PhysX Mod Pack which includes three maps. Make sure to enable "Hardware Physics" under Video Settings in the UT3 settings. Driver release v177.39 or later is required for GPU PhysX hardware acceleration. This pack requires a PhysX-enabled card or a NVIDIA Series 8 graphics card (minimum). Thanks: The Patches Scrolls.
