Help with P3D graphic settings

[ninerwhiskey9W]

Hello

Can someone explain what the various options in the Image and Texture Quality tab do in terms of CPU and GPU load ? I have looked around, and understand to an extent what the end result will be, but the general consesus is each software will have varied results on how the anti aliasing effects CPU/GPU load.

Normally, P3D uses core 2 at 100%, with other cores under load during texture loading once in a while, and GPU rarely sees more than 20% use. I mainly want to try using DL with the NGX withour losing out on smoothness. 

Current settings are :

FXAA : Off, AA: None, Texture Filtering : Anisotropic 4x, Texture Resolution : Medium 1024x102

My specs are :

i7 [email protected], GTX 860M 4gb, and 16BG ram

Thanks
