try -vidmode 800,600,XX XX= your refreshrate, add to the command line halo.exe -vidmode 800,600,85
I didn't need to disable my refreshrate program with this
method.
If using a geforce 3 or 4 add -use11
If geforce 2 -useff
my command line is halo.exe -novideo -vidmode 800,600,85 -use11 -console -screenshot
