This mod increases the size of the normal maps to 4096x4096. This will ijcrease the level of detail for the distant LOD's, but because of the higher VRAM required it will cause a performance hit.
The concept behind this mod is simple: It submits that the normal maps in games like Oblivion with dynamic lighting actually become more important than the textures themselves.
What I've done here is to increase the normal map size for the LODs to a whopping 4096x4096 compressed DDS format and increased the "bumpiness" of it.
The drawback to this approach is that increases the size of the file to 10MB a piece - thus increasing the amount of video memory needed. However, since the normal map is now providing so much more information than before, you really don't need 4096x4096 *textures* for your LODs any more and can use 2048x2048 ones without any noticeable difference.
I suggest using Blade's better Tiling LODs 2048 since that's what I used to enhance the normals.
Unfortunately, due to the nature of the compression used (DXT1) for the DDS files, normal maps tend to turn out rather pixelated and that is true for this case as well - though their 4096x4096 size helps to ameliorate that pixelation a bit.
It's really only noticeable in the very closest LODs while the more distant ones look fantastic. So it will be a matter of taste as to whether you like the look of this mod or not.
I will be releasing a 4096x4096 Uncompressed version of these normal maps -but only people with an extreme amount of VRAM would be able to use this though without a huge performance hit, since the file size will be 50MB a piece!
Probably only cards with 768MB memory or more could handle these uncompressed ones.
