Nvidia control panel settings for development

Hi,

Since I both develop games and play them, I wonder what the optimal settings are for a couple of nvidia control panel settings. I have done a lot of research, but I have never found conclusive answers.

To start:

-Antialiasing - Gamma correction

I’ve heard a lot of things about this.

  1. It doesn’t work
  2. only works with MSAA/CSAA
  3. always turn it on
  4. always turn it off

These can’t all be true so I would like to know the actual answer. If I want the most accurate picture, -let’s say MSAA is used in case it only works with that- will the game engine’s gamma be sufficiently tuned? Is this setting important in modern games/engines?

-Texture filtering - Negative LOD bias

Heard a lot of things again.

  1. allow gives better quality
  2. clamp gives better quality
  3. doesn’t work past fermi
  4. allow with dlss
  5. clamp with AF (which every game has, so never allow unless on dlss)
  6. causes objects to render further or closer.

Every game has AF 16x available these days. Therefore there should be no reason to allow it when not using DLSS. However, does this affect any object rendering, or is it fully limited to just the sharpness of 2d textures? If you look at The Witcher 3, foliage and other textures will be very low quality with it set to clamp. Assuming all modern games use LODs, allow would be the permanent option, except for that they will also use AF. So what is optimal for quality? And above all, can either setting cause artifacts or texture corruption, such as black lines between meshes?

-Texture filtering - Quality

Many people say to just use High Quality since it’s 2024 and GPU’s can handle it. But what does it even do? Sure, it changes 2 settings. “Texture filtering - Anisotropic sample optimization” and “Texture filtering - Trilinear optimization”. But is that all it does? Does that mean that High Quality, and Quality with “Texture filtering - Trilinear optimization” disabled are 100% identical? Or do the settings do something more behind the scenes? Can this setting cause texture corruption, or artifacts? Besides performance, is there any downside to using High Quality?

I have found no proper answers to these questions so I hope experts could answer them here.
