for those that are playing hl2 vr if you didn't already you should probably edit this file. i changed the resolution and refresh rate to match the index. add -tickrate and your headset refresh rate, otherwise it defaults to 720@60. this lightens the physics issues a bit, and it runs smoother of course.
