heres a few more 3dmark tips:
the LOD (level of detail) settings in Rivatuner can have a big effect on 3dmark scores.
it scales from +3.0 to -3.0 for OGL and d3d.
the more positive the #, the less detail it has.
the more negative, the higher detail.
draw your own conclusions
and a bug in 3dmark 2k1 (actually noones really sure why this happens):
if u disable the title screen between tests, your score drops from 200-600 points.
the big fps loser when this happens is nature, which alsohappens to be the most important tests.
so u can disable the non-game tests, but never disable the title screens.
umm, in Rivatuner set ansiotropic filtering in d3d and ogl to force level 0 (or 1). this is off, or nearest point. helps scores a bit cause left to the program believe it uses bilinear filtering.
Timings are much more important in 3dmark (as in almost all proggies) than the fsb.
I ALWAYS run the fastest fsb with max timings, at least always have cas, ras, and rtp(or is it ras to cas?) set to 2. in other words 2-2-2.
most of the time if u run 3dmark with a 133fsb max timings and run it again at 166 with slowest timings, the 133 w/fastest wins out decently.
same with 166fsb max and 200fsb slowest.
umm theres more, ill have to think...
everything Takiwa said is good info as well, and changing hte resolution and refresh manually has no effect on my scores either.
