AGP Texture Acceleration

AGP Texture Acceleration is greyed out in dxdiag and its stopping me from playing some games and ive done everything i can to enable it, from installing chipset drivers to downgrading my graphics to reinstalling directx, i dont know what else to do. my chipset and graphics card are, intel 845G chipset and radeon 9200 PCI version, if anyone needs this information. please help me enable it, i havent been able to play GTA:SA for about 6 months.

>>2 was laughing at you because you have a PCI card, yet you want to enable an AGP feature.  Sidenote: it's even funnier because both of these bus types are outdated for graphics cards.

Conclusion: LOL
