recentlly i bought a new vid card (ATI radeon X700 pro pci express) and it works great with all of my other games except halo. before i got the card i could run halo but with crappy performence settings. when i try to run halo now, it comes up with a message stating that i need to run DXDIAG, so i ran it and it found no problems. i've tried reinstalling halo, and re-installing my cards software. nothing is working; Help?
