Hacked DX10 for XP appears
From developing a new set of compatibility libraries, Windows XP users may be able to run games coded for Microsoft’s new DirectX 10 set of application programming interfaces. Currently DX10 is exclusive to Vista due to the reliance on Vista’s Windows Display Driver, but that could all be about to change. Called the “Alky Project” the reverse-engineered Geometry Shader code may even allow DX10 games to be played on x86-based Macs running OS X as well as Linux.
If you’re game you can install a pre-release version of the compatibility libraries. To install the libraries, users must copy seven DLL files to the System32 subdirectory. But you might want to try this on a spare machine.
