Here's how to 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.
