Unity 4.3.4 lag problem after apply grass

Unity Engine
1

Hi, I have a lag problem with grass…

I’m attempting to make a small map with Terrain Composer and when I generate my map I have a great lag after TC geenerating grass

I tried without generating grass and map work fine even an huge map and many others objects

I tried the same with unity default terrain tool also and I obtain the same resiult after apply the standard unity grass

so my problem is only when I place grass

has someone my own issue??

how can I solve it??

this is not and hardware problem I think becasue my pc specs are : Quad Core Intel Q9500@ 3,8 ghz , 8GB RAM, SVGA HD 6870 1GB GDDR5

thanks in advance

Same. Even in Unity 4.5. I don’t think there’s a fix other than an update. Maybe download a pack with grass textures off the asset store and see if they lag less than the default ones.
