dominion seems to need lots of resources .
i have win xp too but fortunately a quite new pc .
if i play though sp and go to the point of insane wishing / battles etc. with hordes of units i have to wait 5-10 minutes for a new turn being generated .
furthermore i have the ati graphics card problem in battles .
when i run dominions twice , e.g. for sp testing and for taking my turns in mp it gets unplayable even on my only 3/4 year old pc .
since windows xp needs more resources , mainly RaM i guess your pc is now slightly too slow .
2 ideas : first try running dominions in windows 98 compability mode .
if this doesn't help :
install windows 98 again too .
each time you want to play dominions you boot then with windows 98 and for everything else you boot with win xp .
i was not able to find anywhere the system requirements of dominions 2 .
johan or kristoffer could you please post them for edi ?
i guess mainly your RaM and your processor are a bit too slow for windows xp AND dominions 2 .
edi what kind of RAM do you have ? i guess a very slow one
