you are correct!
but in this case vsync nor refresh rate are the problems.
this problem is related for the lattests drivers 182 to 185.
for video cards series 8500 8600 8800 ect. using sli with bridge (not sli via pci)

for some reason other than the refresh rate, vsync,ect. when playing 3d games that use the full beneffits of sli the bridge this flickers and color tears will occur.
now if we remove the bridge and use sli via the pci bus the problem is corrected but the performance goes down.
since i paid to have the full sli brige performance, i will continue to use it.
and at least i see that our friends at nVidia are working on this fix. (is their fault anyways)

and doing the settings that i mentioned on my prior post fixes this anoying problem,
alowing you to use full sli and to use 3d vission as well.

and yes nvidia 3d vision is expensive but with the beta driver 186 they introduced the 3d vision settings for both the $500 gadget and for the $0.40 3d paper glasses

so if you are broke like me, i recoment the cheap glasses. the effects still stunning.
