VR settings   
Hoping someone can provide insight here.  Trying to optimize VR using rift s.  Things are ok, but want the best I can get and frame rate seems pretty low compared to what I have read.  Running 2.5.5, rift s, GPU 2070 super, i7 3.5, 16 gb ram.  It seems like I get very minimal quality changes when I make even drastic changes to PD, graphics settings in game, or by using nVidia control panel.  I have delete the fxo and metashaders folder contents after changes.  And no matter what settings I run, my frame rate in a module is 40 fps, and multiplayer is typically 20 fps in an empty server.  Thoughts of maximizing quality but also improving my frames???
