Oculus CV1 Head Tracking a stuttering nightmare suddenly! Desperate to fix!

[PayneSculptures]

Hello Oculus forum members. I am having a major issue with my system head tracking. Please help!!!:

I have had my Oculus Rift and Touch and new PC since this past Christmas '16, and it worked perfectly in Oculus Home with smooth head tracking on my 2 sensor forward facing setup. About 3 days ago I decided to update my Nvidia driver (and Java to run the nvidia system scanner) for the first time (without noting what driver version shipped with the system). After updating to the  newest official Nvidia driver for my GTX970 (driver ver 376.33), and starting up home, the Rift (CV1) head tracking is completely ruined. It stutters/lags continuously with any movement. Again I don't know which driver version it shipped with but I have tried to install various older versions of the Nvidia drivers and tried to use Display Driver Uninstaller (DDU) to completely wipe the old drivers and re-update to 376.33. Nothing works. Not even a partial system roll back (although I have not fully restored/wiped the system to factory settings as a have a lot of oculus software downloaded). 

Additional info:
- Again DDU was used to clean-wipe the display driver and re-install 376.33 clean and this did not fix in any way.

-The headset is plugged into a USB 3 port that has not had any issues. after this issue I tried updating the drivers and that cause no head tracking so I was able to roll back to the factory USB 3 driver and the port seems totally normal/fine now.

-I have confirmed with the oculus debug tool that ASW is NOT on. 

- I have also made sure to remove any Asus software that even resembles system monitoring add-ins as those can cause Oculus latency issues (for example AI Suite is not on my system).

-I have tried systematically turning off any background system software processes that seem like they could cause a conflict (example printer drivers, Audio drivers). 

Nothing has improved the stuttering tracking at all and I am left with the crushing realization that I now have an $1800 (new PC/Oculus/Touch combo) paperweight. Please advise! I am desperate and my wife is furious to boot!

My system config: 

Manufacterer/Model: Asus ROG G20CB

processor: i7 3.4ghz 6700

RAM: 16gb DDR 4 2133mhz

Videocard: GTX 970
Windows 10 home 64-bit

THANK YOU IN ADVANCE!!!

*NEW Update 2 (resolved - compositor frame dropping on GTX970 appears to be caused by DVI adapter - GO FIGURE): So after uploading a video to see if my "tracking/stuttering" looked like others I found that it did not. Mine was a constant strobing unwatchable mess while most other videos I found online were more subtle drifts and pops" I determined that something is indeed causing my system to just drop frames after using the oculus debug demo (with built-in frame counter). This showed me that the compositor specifically was dropping frames. Scouring message boards for that specific problem I came across this entirely unconvincing and yet amazing message: "I managed to fix this by changing my primary monitor from dvi to displayport. I can't explain it, but I dropped out of college." LINK: (https://forums.oculus.com/vip/discussion/43905/compositor-frame-drops-every-second-stuttering-in-headset)    - "No way is this going to work" I thought. Yet strangely it FIXED the problem. No more need to USB balance! It's fixed! EUREKA! BTW: This is the only place i've seen this suggested and it seems to be right on!*

I understand that this issue has been acknowledged and that a fix is in the works, but in case more info is needed: I'm having the same issue. Extreme stuttering makes Rift unusable.

Cable does not appear to be damaged. Tested on office PC and runs perfect. Unit was purchased October 2018 (15 months ago).

Sounds like the recent v12 update problem. The Rift ran perfectly last time I used it at the beginning of December.

After Oculus home (or a game) loads, after less than a minute, extreme stuttering begins. The stuttering happens every 2 seconds or so. It directly correlates to the CPU and GPU performance graphs which spike and dip every 2 seconds (screenshots below).

I have tried the Oculus app PTC version. I have the latest NVIDIA drivers and have also tried rolling back to NVIDIA driver 436.30 from September 10th.

Gaming system with problem is a laptop Intel Core i7-8750H CPU @ 2.20GHz NVIDIA GeForce GTX 1070 8GB 16GB RAM

Office desktop PC tested working perfect: Intel Core i7-3770 CPU @ 3.40GHz NVIDIA GeForce GTX 1060 6GB 16GB RAM

No it's not recent problem, for me it started already on some 1.3# version, can't remember the exact version. Might be 1.37, same time the panell pullout from 2nd monitor stopped working(with the instant exclamation marked window, when window is pulled out). The "still show" only stops when beta tabs "restart system" is ran. And it's Home2 problem, because when Homeless is activated, there is no "still show".

EDIT: My systems lagging although starts at the start, not after a few minutes.
