Running in Win7 I've found mine doesn't like having 2 sensors plugged in.
It might be that the one mounted on the desk wobbles due to the wheel, but I don't get this in any of the free games that came with my rift when I tried them.
Despite what it tells you it will happily run the touch sensors with only 1 sensor, although you'll probably need both plugged in to set the system up.
The other thing I'd advise is to check exactly what your GFX card manufacturer software is upto. When I enabled mine it detected that I run VR for AC and changed loads of settings it 'improve' it.
For some reason they made things worse for me, while frame rates do drop with a lot of cars around I'm getting better performance still with graphics set to almost full whack - just with AA disabled and smoke turned down a bit.
This is with a 1070GTX and I7 with 12Gb of RAM. Next planned mod is to max myself out at 16Gb of RAM.
Then look into dual boot so I can go Win10 and maybe upgrade a bit more - Oculus essentially don't bother to support Win7 so if you run it expect to do a lot of searching in their forums as it seems to be the only place you'll get useful help.
I recommend you start by downloading and installing the software from the website now, there are numerous bugs (For W7 at least) which may take you a good number of hours to work around because Oculus haven't bothered fixing them for about the last year. Not what you want when you have a shiny new toy to play with
Apps-wise I recommend Helicorsa. You'll only have the normal mirrors for what ever you drive in the rift. The 962 isn't even the worst car in the game for placement either
