If I play with a Valve Index, will I need a biofeedback device? If so, what is the cheapest I can find?

I am using a camera and Polar H7 heart sensor together for the game. The camera is freezing (turns off) very often for one second. The led indicator turns off on the camera for one second and the game lagging at the same time. My system: cpu ryzen 3 1300x, 16 GB ddr4, gpu gtx 1060 6GB. The camera in an old Microsoft webcam. But it is working well with other softwares no freezing. Without the camera the game is not lagging. I experienced lagging only with the camera even with the lowest graphic settings 800...

I am trying to get all of the achievements of this game and for some reason, I have gotten all of the neuro advanced stuff except for the part in the guide that talks about an area that used to have the coffee machine there. like when the coffee machine disappears from the kitchen. so am I supposed to like look at that area before going to the third stage or is this some kind of glitch I have encountered? or it is somewhere else? the hint of what is locked for me is "I never liked coffee anyways". I hop...

The need to constantly push in the thumbsticks to move is uncomfortable enough that I find the game unplayable. There should be an option in the input section to disable this.
