The majority of the update works just fine for DirectX 8. Contracts, drops, coins and maps—they all work! Unfortunately, the uniquely decorated weapons do not. When you are playing with DirectX 8, you will only see the basic, undecorated weapons. This is true both of your own and others' weapons. To gain access to unique weapon decorations, run Team Fortress with DirectX 9. Players running DirectX 8 should remove
mat_dxlevel from their config files and add
-dxlevel 95 to their launch options.
