Are you using the four by four texture option. If so you can get them to load in by just doing a 360 on the spot. If that cures the problem then you could Thu, 19 Nov 2009 13:54:23 GMT Drew Stainton http://tech.groups.yahoo.com/group/vtp/message/5698 http://tech.groups.yahoo.com/group/vtp/message/5698 Stefan, Hmm, I hadn't thought of doing that. I see NVidia has their texture tools online so I'll grab those and give it a try. Thanks for your help!

Mipmapping and S3TC compression will also lead to a stutter if enabled. It is best to precompress and pre-mipmap the textures in Windows DDS format.

If you mean you've actually modified the vtTin3d code (rather than using surface types and vtTin3d::SetTextureMaterials) then i'm afraid it's a Wed, 18 Nov 2009 23:10:25 GMT Drew Stainton http://tech.groups.yahoo.com/group/vtp/message/5694 http://tech.groups.yahoo.com/group/vtp/message/5694 Ben, Thanks for your help. I don't have structure paging turned on. I have a single TIN.

You don't get delayed loading into RAM unless Wed, 18 Nov 2009 17:56:01 GMT drew_stainton http://tech.groups.yahoo.com/group/vtp/message/5692 http://tech.groups.yahoo.com/group/vtp/message/5692 Is there a way to have Enviro pre-load all objects and textures to avoid stuttering as I fly around for the first few minutes?
