Problem with a shadow in Tourist Trophy

[turiboh]

Hi everyone
i found this bug in tourist trophy.
A shadow that appears constantly in the road
and when i do a crash, i can't see the road or the terrain.
There's like an object or texture that invaded the terrain.

Here some screens:



My pc:
amd apu a10 7850k = quadcore 3.7 ghz, vga 720 mhz 2 gb.
Ram: 8 gb 2133 mhz

The shadow disappears when i turn on the directx11 software mode.
But the game runs very slow. In hardware mode, both dx9 and dx11 run very well.

I also own gran turismo 4 that have the same engine of tourist trophy but it run good without bugs.

I'm Italian, sorry for my bad eng

TOURIST TROPHY (PAL): Set Brightness to 0 in the game options to display the tracks correctly. Set EE/IOP---Clamping Mode---Full, VUs---Clamping Mode---Extra. You must use a PAL Bios to avoid locks when saving in a 8MB memory card.

set skipdraw hack to 1 to solve the shadow issue.

i've just set it to 1 but there is always an issue.
the shadow of the bike is not realistic at all.

this happens only in "time trial" mode. not on races.
