Nvidia tweaks to SH3/SH4

[Rubini]

Hi Sailor _X,

Yes, nhancer no longer. I also use Sh3 nvidia control pannel and the Nvidia Inspector.

My settings on nvidia inspector is below.

Some comments and tips:

1. The settings and tips continues almost the same that we have on the first post when using nhancer
2. If you dont have sun halo please report to your nvidia control pannel and *DISABLE* the gamma correction in your global and sh3 settings (and obviously on the nvidia Inspector too). Double check here!
3. I added a 4x sparse grid ssaa and the related negative texture lod that seems to add some better visuals (just allowed using nvidia inspector I think)
4. Anyway, seems that actually using only the Nvidia control pannel (with that basic tips: max 4xMSAA and no gamma correction) is enough to have a good/best nvidia image for sh3, no more necessary to use Nvidia Inspector or anything more then.
