Been playing with my new X1950XT all day and while i really cant complain about its performance, it never seems to go into its 3dmode. I noticed while looking through CCC that it was requesting a core/mem of 621/1800 however was only getting 500/1200....no biggie, thats its 2d mode. Using ATI Tray Tools I monitered the clock speeds while playing oblivion and they stayed at this speed however. Anyone have any idea whats going on?
