2 multiplayer game questions

hi, i was wondering if someone could clarify this.

i played a game with one of my friends and as far as i can remember, we could choose the difficulty of each AI and ourselves as well. i think we chose warlord for everyone and for ourselves but in the game the AI was ridiculously easy. what should i do to have the AI at warlord/prince difficulty??

also, i run civ5 on the windows portion of my mac and i have to play it through windows to play with a PC opponent otherwise it doesn't work (thx to Firaxis for making things more complicated). the game lags too much for the type of computers we have so i suspect this is the reason why. by the way, she plays with direct x 10 and i play with direct x 9 (i don't if this could interfere). anyways, whatever the reason, i'm looking for tips to make the game faster: smaller map, less civs, low graphics etc. can you suggest something. i don't want to wait 20 seconds before my turn each time.

thx.

 

1-If you put difficulty at warlord for humans and AI, AI play at warlord difficulty and you get warlord's bonus for happiness and barbs. But in mp the AI sucks more than sp. Should be repeared for next patch from whst i've read.

2-I heard that dx9 is better under mp mode. You should try to play both with dx9.

 

ok merci.
