hi.  i am having problems getting quake 4 mulitplayer to work online when i enable my sli (2 x 7800 gtx).  i try to log on to a server and it locks up at the load screen, or the screen goes black and stays that way, i then get a windows error message and get dumped to my desktop.  

if i disable the sli, it runs perfectly fine.  i also have dual core 4800+ proc., and x-fi fatality...i run open al, and dual core options in game.  i have tried with both these options on, and off, and am still having the same issues...so im thinking its a video setting, but there is no sli option in the settings menu is there?  

also, i have checked and rechecked that i have all the latest drivers for all of my hardware, as well as the latest patch....

lil help please.

tx.
