does any body have problems with terrain on vita

does any body have problems with terrain on vita ? is there any alternative solution to have a terrain without big hit in the framerate

 

Yeah, terrains are a big performance hit, on all mobile plattforms. (tried terrains on vita, it was horrible, sometimes it didnt even started the lvl) For mobile platforms, you should convert your terrain into an mesh, for example with this tool:

thanks for the advice i got runnig a terrain at 32 frame but i was using advance terrain shader i think the default one is a fixed shader or something like that i think the issue is in the shader more than a geometry problem
