I got a valve index, and I'm noticing a lot of games have watery distortions when I whip the camera around. What setting fixes that? I googled 'valve index watery distortion' and nothing really came up.

Isn't there a setting where you just tell steam to figure out the optimal configurations for the graphics?Or is it individual for each game? Some games look great, other look like PS1 garbage, screen door, watery distortion. And for the games that look bad, none of the reviews on steam mention bad graphics so I assume I need to fix the settings.
