Nvidia Control Panel - Virtual Reality pre-rendered frames

r/GlobalOffensive is the home for the Counter-Strike community and a hub for the discussion and sharing of content relevant to Counter-Strike: Global Offensive (CS:GO), and Counter-Strike 2 (CS2). Counter-Strike enjoys a thriving esports scene and dedicated competitive playerbase, as well as a robust creative community. This is the largest and most active CS sub on Reddit. On the nvidia control panel , the setting Virtual Reality pre-rendered frames is by default at 1 , changing this setting to application controled changes the way csgo “feels”, I feel like the way I aim changed to be more “precise” and faster but I cant seem to control my spray. This is not placebo, something does change but I cannot tell what it is, same for pre-rendered frames set to 1. Can someone explain what is that option and what is the difference I feel ingame?
