There is a tweak regarding joystick bindings, but it is the same in Windows and in Linux. The default Valve Index bindings are very bad. I went to the community bindings and found one named "DOOM VFR Configuration for the Index Controller". It requires you to once having started the game, use these commands in the console: "bind STEAMVR_PRIMARY_AXIS2 _lookLeft; bind STEAMVR_PRIMARY_AXIS3 _lookRight; bind STEAMVR_PRIMARY_AXIS4 _jump; bind STEAMVR_PRIMARY_A _weapnext; bind STEAMVR_SECONDARY_A _weapprev". Then it goes smoothly and you can turn smoothly instead of instant, which makes the game much better to play. Teleport still works, which you might need to reach some areas. If you like these bindings, you can just locate the /steamapps/common/DOOM VFR/base/vr_default.cfg, edit it with a text editor and add these bindings one each line at the end of the file
