I have a 1660 super and can confirm it works for Low-Fi, however I have 64g ram and a 9900k. To start Low-Fi, I start SteamVR first, then navigate to the .exe from my desktop file manager inside VR
I'm going to just use my best buy card and maybe get 32 haha... Yea, I tried to run it again and it crashes the computer, just freezes... thanks again I gotta play this game ASAP
