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.

You may have missed something. He stills demands a feature with AGP in its name while using a PCI card.

Also, GTA:SA is good game. STFU and GTFO.
