Okay... So with 64 megs shared RAM, BZFlag presents no obstacle, TuxRacer works like a charm, and Cube runs without a hickup. So what exactly are the limits of this cheapo video hardware? Would it choke on Quake 3, for instance? Would Nexuiz run with the lighting effects tuned down, if I somehow got it not to terminate itself shortly after startup? Or, as I'm suspecting, is Cube just an extraordinarily bloat-free program?
