can AA and AF be turned on anywhere

[candle_86]

How do I enable these, I can't pull up my Nvidia control panel for some reason. I want to force AA and AF, and the AF setting EF2 gives in advanced seems lacking, is there something I can do in the config file?

AMD Athlon 64 3500
Nvidia Geforce 6800GT SLI
1gb DDR400
DFI Lanparty SLI Ultra-D
Windows XP Home SP2

any help is appreciated on this, Id love to get 8xAA and 16xAF

I'm afraid there are just the settings from the menu available:

seta r_ext_nv_multisample_filter 1;
seta r_allowExtensions 1;
seta r_arb_multisample 1;
seta r_anisotropicFiltering 1;
//to applay settings now:
vid_restart
