serious slowdowns on some maps

[francoisD]

i do not speak of map size, but map type. in the desert of north africa i played one delay battle, and everything was the same, but the presence of trees!!!

the waiting time jumped from a few seconds (let say 1 minute when taking into account a few key points) to half an hour...

i do not think my pc is relevant here.

by the way it is modest, a one ghz whith many applications in the background

but, again, i was perfectly enjoying the game so far.

until i met a map covered by trees! so i asked if it was normal

or if i should check my computer for a virus

am i clear?
