I have a self built gaming PC which has had no issues with games, and have just added Oculus Rift Touch Bundle. At first everything is fine, perfect VR experience, but after about 20 minutes to half hour of use, the tracking starts to get jittery, the audio sounds garbled and corrupted, and games start to lag. Exit out the VR menus and you can see in Oculus application that there are poor tracking quality issues, either on the sensors or the headset or both.
I've tried every USB port combinations (USB 2.0 and 3.0). I've disconnected all USB devices except mouse and keyboard and the 3 Oculus USB plugs. I've killed all other applications with Task Manager. I reboot the PC and things are ok again briefly but then it all goes wrong again.
Please help diagnose.
