i recently bought a game named painkiller that requires direct x and when i try to enter the game it say ERROR:directx 9 renderer if u can help me plz email me

I'm guessing that game requires a DirectX 9 generation video card (Geforce FX or ATI Radeon 9550 or greater) to run. Chances are it will need shaders to render the graphics but you could try software TnL emulation with 3DAnalyse

It's possible to run Painkiller on a Voodoo4/5: https://www.3dfxzone.it/dir/news/3dfx/painkiller/index.htm
