@DgekGD , i like your approach because i can use the same VS and PS in differents classes 
!
@Racoonacoon well right now i don`t have the implementation made of Quad2D on my current "Engine"(DX11), i wanted to ask before i do it because DX10-11 works different, but i do have my DX9 version ,
void RenderManager::DrawQuad2D (CTexture* texture, Vector2 position, int w, int h)
{
// position = [0]
//
// [0]------[2]
// | |
// | |
// | |
// [1]------[3]
Vector2 coord_text[4];
coord_text[0].x = 0.f; coord_text[0].y = 0.f;
coord_text[1].x = 0.f; coord_text[1].y = 1.f;
coord_text[2].x = 1.f; coord_text[2].y = 0.f;
coord_text[3].x = 1.f; coord_text[3].y = 1.f;
unsigned short indices[6]={0,2,1,1,2,3};
SCREEN_TEXTURE_VERTEX v[4] =
{
{ (float)position.x, (float)position.y, 0.f,1.f, coord_text[0].x, coord_text[0].y} //(x,y) sup_esq.
, { (float)position.x, (float)position.y+h, 0.f,1.f, coord_text[1].x, coord_text[1].y} //(x,y) inf_esq.
, { (float)position.x+w, (float)position.y, 0.f,1.f, coord_text[2].x, coord_text[2].y} //(x,y) sup_dr.
, { (float)position.x+w, (float)position.y+h, 0.f,1.f, coord_text[3].x, coord_text[3].y} //(x,y) inf_dr.
};
m_pD3DDevice->SetFVF( SCREEN_TEXTURE_VERTEX::getFlags() );
m_pD3DDevice->SetTexture(0, texture->GetD3DXTexture() );
m_pD3DDevice->DrawIndexedPrimitiveUP( D3DPT_TRIANGLELIST,0, 4, 2,indices,D3DFMT_INDEX16, v, sizeof( SCREEN_TEXTURE_VERTEX ) );
}
Well i based in your suggestion , i think i will do some sort of XNA's "SpriteBranch", and that class can be instantiated once, and be passed on the "Render" method, instead of the "RenderManager",
Thank for your greats advice
