sAntiAliasing

sAntiAliasing sets the kind of anti-aliasing (AA) used. Leaving it blank disables AA. FXAA (Fast Approximate Anti-Aliasing) costs little performance, but blurs the image, albeit not as much as TAA. TAA (Temporal Anti-Aliasing) costs more performance than FXAA, reduces more jaggies, but can cause flickering at places. TAA can be further modified via the various fTAA- settings in Fallout4.ini > Display, but does not improve much.

Default is TAA. Recommended to leave it blank and use SMAA via ReShade.

sAntiAliasing=
sAntiAliasing=FXAA
sAntiAliasing=TAA

sD3DDevice

sD3DDevice appears to only be used by the Fallout 4 Launcher to detect the correct preset. It has been verified that it is not used by the game itself, just the Launcher. If Fallout 4 is not using the correct graphics card, fix that elsewhere (i.e., the driver).
