prikladam jedno vysvetlenie z netu od jedneho manika:
Just in order to explain a couple of things that you might not have gotten at all:
This DX10 fix doesn't provide DX10 enhanced graphics capabilities on XP systems, it just disables them in order to have them compatible with DirectX 9.0 systems. Another point: only a couple of DX10 games run on XP in 3D hardware mode when this RC2 mode is used, the rest of them is running only in 'programme' mode which means no hw acceleration except of native <=9.0 API calls is performed.
When any game is programmed in pure DX10 mode (only DX10 API instruction set is used by game developers), no HW acceleration will be made and the game will be unplayable on DX10 RC2 XP mod. In such cases, the game will even refuse to start.
