I am using an ATI mobility radeon hd 5470 and have tried both Catalyst 10.6 and 10.7. Most games work fine, but mount and blade crashes at regular intervals, usually when I am entering a new area. The same thing will not always crash it generally. Here is the output from one of the crashes: Code: fixme:d3d:color_convert_argb_to_fmt Add a COLORFILL conversion for format WINED3DFMT_D16_UNORM fixme:d3d_texture:basetexture_generate_mipmaps iface 0xea2cb60 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0x3ffa3ed0 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xe39beb8 stub! fixme:d3d:color_convert_argb_to_fmt Add a COLORFILL conversion for format WINED3DFMT_D16_UNORM fixme:d3d_texture:basetexture_generate_mipmaps iface 0xedc8560 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xed2c5b8 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xee90c50 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xee64210 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xee64480 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xea2cb60 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0x3ffa3ed0 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xe39beb8 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xea2cb60 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0x3ffa3ed0 stub! fixme:d3d_texture:basetexture_generate_mipmaps iface 0xe39beb8 stub! wine: Unhandled exception 0xc0000417 at address 0x7e720023:0x0069cbd3 (thread 0034), starting debugger...

Any ideas what could be causing this or how I could debug it better?
