Skybox Texture Compression problems

Hi,
im currently working on a Space “simulation” with real physics, gravitation…
I succesfully imported a 6x2048 .dds cubemap with photoshop and the nvidia tool. (it took about 15 minutes to import the 96mb .dds file :D) But when i looked at the texture it really looked blurry. How do i improve the texture? What compression settings (LOD_Bias is 0, i used TC_HDR) are the best for skyboxes? Where is my fault?
Im sorry that i dont have a screenshot of the texture right now, i will deliver soon (im at work now;) )

thanks in advance

For anyone who has the same problems, I solved them. I set it to “no mipmaps” and “tc_hdr”. Now it looks really awesome without blur.

Nice one man.

I believe on import, you can set your lodgroup to ‘skybox’ or something similar; which should also help with compression.
