Ahh ,I see, Still seems that some games like to kick out when the visual demands are put on the video card, IE: BattleZoneII. This game runs for hours in 640*480, but will kick you out very quickly in 1024*768 with some bells and whistles on. Same goes for Unreal Tournament. Maybe its just a Tnt2 thing as i have not heard or seen reports of Voodoo 3, Matrox, or Savage2k performance.
Any Ideas??
