what's meaning of "enable hmd mask"?

in new version of DCS, in VR Options, a new option is enable hmd mask, what's meaning?

[MadKreator]

HMD mask has been in for a long time. It has to do with the application of anti aliasing. Enable it then theres a slider to select the “box size” or percentage of the screen. Inside of that box it will apply antialiasing/ smoothing. Outside of that it will not. Basically a way to inch out a bit more performance so it’s not “smoothing” out the entire screenspace.

Is this with MSAA only or does it work with DLAA?

AFAIK it only removed the effect not the processing cost, and it is only really for MSAA

thanks for your answer. i thought it is an option about Mixed Reality(XR) such as Varjo, Varjo use a 3D mask model to mask the virtual with the reality.

Oh that would be cool! I’ve only done that on the Quest 3 using Virtual Desktop app and Open Kneeboard. The mask in the settings  was/is sort of a very basic version of foveated rendering. Only it just affects MSAA in the “view” area, and not the actual resolution like FFR

HMD mask just crops the mirror image on your monitor to the HMD view. It is not the same as MSAA mask. That does not appear to do anything.

Oh, was thinking it was to do, in part with MSAA mask. My mistake. Honestly cant say I’ve ever paid much attention to the VR mirror.
