Are you sure its AGP's problem?

coz i played all the games u said on my computer, they all worked fine.

The only software that i cannot use properly was Win3.1, coz there was no driver supported under Win3.1!!

You may check it's other hardware or software's problems, such as sound card.

I Suggest that you use pure Dos to play those games. I use PC-Dos 7.0

My card is AIW Radeon AGP!!
