store texture in vram

Hi there a problem concerning the storage of texture ( i presume )

I use this code for loading 8 meshes

Mesh1= LoadMesh("1.x")
Mesh1Tex= LoadTexture ("2_2048.jpg",256)
EntityTexture Mesh1,Mesh1Tex
EntityFX Mesh1,1

and so on on for the 8.

Whern i run the panoramic , i get saccade, which i havent as i was using a single mesh with the 8 textures.
I've tried the flag 256 on Loadtexture, but no result

I presume blitz is removing the texture from vram for object which are not visible.

Flag 256 isn't for having always the texture stored in Vram ?

What is the solution ?

Thank's
