Hi Nick,

We never really communicated much, both on each sides of their forums, I really have a question, for which I would like your opinion.

There has been lots of here and there about how to set up Anisotropic Filtering in FSX.

There are basically two ways of achieving that:
1) internally in FSX, Nvidia Inspector set to application controlled (reset to defaults)
or
2) FSX set to trilinear and in Nvidia Inspector ser "User Defined / Off" + 16x

When comparing static pictures of both, there are no real visual differences. Though when moving around, there are visible differences on what shimmers:
1) more shimmering visible on water (gets more extreme with certain REX textures and/or higher altitudes), less or even no shimmering on runway and taxiway lines
or
2) virtually no shimmering in water (tested more textures and various altitudes), but runway/taxiway textures shimmer and alias more

I don't quite get it why each applies where they want, I thought Aniso is Aniso.

But what is extremely puzzling, the performance difference in a certain scenario, which is actually very simple, is amazing: 114fps internal aniso vs. 31fps NI aniso.

The original explanation including some screenshots, can also be found on my blog (can't post the link here, but it's easy to find via Google).

Also, you recommend using 16x in NI. I would very much like to know why you recommend 16x in NI and your opinion on my tests above!

Note: also I did not yet test on the clean FSX, so something else might be interfering, but I'll get around that!

Best
