At the moment i dual boot win2k pro and win98se. Becuase, i can't be bothered to wait a couple of mins to shutdown and boot into win98 just to play my games i've installed them under win2k and am trying to play all my games in win2k. So far it seems to be ok except rally masters which is just far too slow and juddery. which got me thinking if rally masters got such a big fps hit then my games are likely to be taking some kind of a hit.
So, if you know of any game tweaks for UT, quake3, rally masters, motorcross madness, deux Ex, or any others then i would appricate it.
