*******POSSIBLE TEMPORARY FIX********
DISABLE DIRECT DISPLAY in steam - I've been having the weird headset lag, about 300-400ms lag between headset movements and tracking. All stats are in the green, but that still happens.
With steam direct display enabled (the normal way) I have this problem. With direct display disabled, it goes away COMPLETELY. You have to get it to treat your headset as a monitor, and then open steam vr and play like normal. THIS CAN BREAK SOME GAMES as steamVR doesn't like non-direct display very much. A lot of games can cause it to go funny until you click on the screen in steam vr with your mouse. Good luck everyone. @Exavolt give this a shot let me know if it works.
@Exavolt were you only having framedrop issues with the pro 1, or were you having the 200-300ms headset tracking delay as well? The DD thing only fixes the delay from what I can tell, I don't know what to do about anything else.
