you can use the total war attila profile.took the 2nd one with the lesser downloads.It runs pretty well from the get go.
Only thing you have to take care of is not using Geometry 3D, otherwise it will crash when entering world map or a battle.
Use Z-NORMAL instead and it will run, in DX11 of course.
Another thing i had to do was set 3 HUD sliders in the vorpx menu to
1.00, otherwise the mouse cursor didnt point at where i clicked.
