Painkiller (The old one)

[metas]

I have Painkiller (The old one,not Overdose)and although it works ok with 3d Analyze, it seems that there are some problems with TnL technology since some parts of the environment(the floor sometimes but mainly the walls) are totally black!Of course I tried to change the Gamma(foolish solution) and nothing happened.Do you think that this is the emulator's fault? I have a dual core proccessor(2,7GHz),512 ram and 64 MBytes On Board Graphics Card.
