--- Comment #6 from Christoph Hohmann reboot@gmx.ch 2010-01-31 11:10:28 --- I tried it and my X did not crash, but League of Legends complains that an unknown DirectX error occured. I ran it with WINEDEBUG=+d3d9,+d3d,+relay and the log does not show any calls to D3DXCreateTextureFromFileExA, so I guess with the native driver the game has other issues before it tries to use this function of DirectX.
