Ty for reply. What I find confusing however is when I check d3d_texfree I seem to have alot of video memory free, but I still get error messages when placing to more models with fairly big textures (2048x2048 with normal maps too) in the map (it does not seem to be related to something specific).

The error message -> "Error E2005 - Can't create D3D texture
The texture format is invalid or unsupported by your video card. Very old video cards often don't support DirectX 9 and can not create textures of the given size or format."
