When I try to activate AH2, I get a message saying "Your video adaptor does not support Hardware T&L. It will not be able to run AH2". I have downloaded Direct X 9.0. I have a Dell Optiplex 170L computer, Pentium 4, with an Intel[R] 82865G graphics controller and an ATI Rage Ultra video chipset/card or something or other (not easy to puzzle out from the Dell web site). AH1 ran just fine- so why the problem with AH2? I have 512 meg RAM, 3.0 GHz Pentium 4. Do I need a new video card- if so, what's my options?
