Fix Fallout VR 4 FPS/TAA/player height issues

First off, somehow, this is a temporary fix. Please apply the official update or patch whenever it's available.
step 1: Make sure your game not running.

step 2: go to your Documents/My Games/Fallout4VR folder in the Drive C. Refer to the below img.

step 3: Locate, open & edit the Fallout4Custom.ini this way:
[General]
sStartingConsoleCommand=cl off
[Display]
iLocation X=555
iLocation Y=90
fTAAPostSharpen=0.675
fTAASharpen=1.0000
fTAAHighFreq=0.8000
fTAALowFreq=0.5000
fTAAPostOverlay=0.675
[VRDisplay]
fRenderTargetSizeMultiplier= 1.0
Hint: right click on that file, check out the "Open with..." section, and use Notepad to edit the Fallout4Custom.ini file. Refer to the below img.

Note: if you could not find that file, plz create it by duplicating another one of the .ini files, deleting all the original contents, and replacing with what we have mentioned.
step 4: save the change you made, try running your game; exit the game, and re-open Fallout4VRCustom.ini, add the following line:
[VR]
fVrScale=80
fKickbackMaxOffset=20.0
Hint: Change the value for fVrScale from 80 to what suits you best based on your own height.
step 5: BACK UP current file, and download this modified Fallout4Prefs.ini file from goo.gl/4kioGY - this helps get the main FPS boost.
