When i launch the game for the first time, i have these message in output console : Code: err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 3 on device context 0x3c8. err:d3d:context_choose_pixel_format Can't find a suitable iPixelFormat err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 3 on device context 0x498. fixme:d3d:wined3d_get_format Can't find format WINED3DFMT_R24_UNORM_X8_TYPELESS (0x49) in the format lookup table fixme:d3d:getDepthStencilBits Unsupported depth/stencil format WINED3DFMT_UNKNOWN. err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 27 on device context 0x4a0. err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 15 on device context 0x4a8. err:d3d:context_choose_pixel_format Can't find a suitable iPixelFormat err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 3 on device context 0x4b0. err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 3 on device context 0x4b8. err:d3d:context_choose_pixel_format Can't find a suitable iPixelFormat err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 3 on device context 0x4c0. fixme:d3d:wined3d_get_format Can't find format WINED3DFMT_R24_UNORM_X8_TYPELESS (0x49) in the format lookup table fixme:d3d:getDepthStencilBits Unsupported depth/stencil format WINED3DFMT_UNKNOWN. err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 27 on device context 0x4c8. err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 15 on device context 0x4d0. err:d3d:context_choose_pixel_format Can't find a suitable iPixelFormat err:wgl:internal_SetPixelFormat Invalid operation on root_window err:d3d:context_create Failed to set pixel format 3 on device context 0x4d8. I saw in Bugzilla that Dead Space 2 and Age of Mythology have the same problem but there isn't solution.
