 It is caused by those patches (they depends on each other):

 [2/6] WineD3D: Make pixel shader input an array
 [3/6] WineD3D: Pixel Shader varying indexing
 [4/6] WineD3D: Add a max varyings member to the gl info structure
 [5/6] WineD3D: Handle ps 3.0 varyings in a different way

 You can easily test performance with Nvidia SDK demo
AntiAliasingWithTransparency.exe not every game or application is affected
by this regression. Every affected application is using PS 3.0 (NFS
ProStreet, Call of Duty 4, Unreal Tournament 3).
    

I guess only the last patch finally "activates" the slowdown, right? It sounds 
like a fallback to software rendering by the driver. I thought the driver's 
shader optimizer can sort out issues like that, apparently this is not the 
case everywhere. What GPU do you have?
