Just reading through some of these old post and was wondering what would be best for my system. I have a AMD dual core 4800+ 2.4GHz processor, 2Gb ram and use pci express NVidia 7800GTX g/card. I am currently running Vista o/s but have just started running UT in XP compatability mode. Would open gl drivers work better for me? I just installed UT and let pc decide, never thought of using open gl before and is there a lot of work to do user side to install and get working ok? Cheerz
