I tryed BVE 2/4 with GeForce GTX 480 on same PC and same Win XP SP3, testing all drivers available (about 30 versions

hock

, but now this happens (with GeForce 7900 GTX, BVE worked with driver not later than 266.58 version):
BVE 2 (Uchibo Line):

BVE 4: (Uchibo Line):

Seems something about vanishing point of the perspective.
With all other routes is the same.
If I enable or disable anisitropic and/or antialiasing filters there is not changes.
DirectX is updated at latest version available for XP.
If I disable Direct3D Hardware Acceleration BVE 2 works and BVE 4 does not work transparents of the cabin, but I wish that it also works with Direct3D Hardware Acceleration.
How can I solve the trouble?
