I have for now a half a year suffered from terrible performance with Rift. Three camera setup, tried with extension and without extension cables. Sensors are in two USB 3.0 and one USB 2.0 ports, tried drivers for USB extension card from Microsoft as from manufacturer. Tried sensors on the motherboard alone etc.
Setup is tested in dark room (no sunlight) with closest distance (1 meter apart each sensor so extreme close-setup) as with one or two sensors instead all three.
The problem is that Rift draws everything twice. Even looking just one eye, everything is ghosting. If I disable ASW then everything is super smoothly ghosting, but if I enable it it just draws ugly everything that is hands and head movements. This is visible everywhere, most of the time. Like just going to Oculus Home, all runs smoothly. If I keep head still but move hands, they are double drawn. And the strange part is that I see them twice so that if I touch some controls so that virtual hand goes to fist or moves finger, the ghost model doesn't, while the normal hand does. The ghost always stays as static open hand form with both hands. If I turn head, everything gets ghosting.
Every graphics games etc run 90 FPS, but all hand and head movements cause serious ghosting.
And that ghosting can not be recorded on the duplication on computer screen, but is only visible on HMD. I can run even extremely heavy CPU games like DCS World without any graphical problems (45 FPS static) but only if the HMD or hands do not move. Once I turn or move head or I move hands, either hands or everything goes double drawing.
I just today ran the Oculus Debug Tool and it gave even on the Oculus Home a performance headroom -15% but 90 FPS. Every animation, graphics etc is smooth unless I move hands or head.
I have no monitoring softwares (MSI afterburner etc etc etc), nor any anti-virus, nor any video recording (Nvidia Shadowplay) nor any V-Sync (even for desktop). And even Steam is not turned On (its OpenVR mode).
I don't want to uninstall Oculus Home as I will lose the games saves and progress...
