Campaign map lag

[Gilthine]

Hey guys I have downloaded this mod recently and its really good.But on the campaign map on the places where there are a lot of trees my FPS drops to like 5.I put all the campaign map settings to low but still lags.
I suspect its the trees with their shiny effects... is there a way to remove the trees or make them of lower quality of something? pls help

Are shadows turned on? I've found that's the biggest drain, and always turn them off- on the campaign map and battle map.

Unfortunatley I have turned off the shadows.And the problem is surely in the fancy trees because it only lags in gaul and germanics area where there are a load of trees with their gliterry model.So I can look pretty much anywhere on the campaign map without trouble except the those areas.So this means I can't play with britons gauls germans or juli.And I can't conquer that area with any other faction either.So thanks for trying to help but it really is the damn trees.
And one thing I've noticed that some trees dont have like shiny effect and they dont really cause me much problems,but the ones in the modern france area are really god damn shiny and sparkly.Is there any way to remove this or anything that help my fps on those areas please help.
