I have Intel(R) 82915G/GV/910GL Express Chipset Family it has pixel shader 2 and with this card I can run almost all games(by using 3D analyzer) but still I cannot run Prince of persia 4 : The journey begins, which requires pixel shader 3. I tried the following setting:
1)emulate HW Tnl caps
2)Emulate pixel shader caps
3)Emulate bump maps caps
4)Emulate max.sim. Texture
5)Shaders
6)Textures

After applying these settings I got the intro screens but when I got to the menu there were no texts on the menu. But somehow I started the game but then the game crashed.

So, can someone please give me the settings to run this game or tell me how to emulate pixel shader 3?
