Distorted blocks and weird wave effect

[Gungu Ginga]

Beat Saber and pretty much all of my other oculus games are having graphical difficulties. I pretty much get this wave/ distorted effect in beat saber that is really noticeable when playing. Other games, like robo recall and arizona sunshine seem to have slight frame drops when shooting guns. Nonetheless, these distorted blocks are really annoying when playing a song and I was just wondering if anyone has had this issue in the past and resolved it or if there would be any useful feedback; anything would be much appreciated.

Things I have tried:
Reinstalled Beat Saber, Oculus and Windows 10.
Rolled back drivers and uninstalled using DDU.
Replaced every hardware component in my computer except my hard drives/ sdd.
Replaced Oculus Rift itself three times (returned)

My Specs:
Gtx 1070 ti
i7 - 6700k
12 gb corsair vengeance ram
750w corsair psu
Gigabyte gab250m ds3h

Side Note: When running any oculus game/ app my gpu usage is abnormally low - around 20-30 percent and same with cpu - around 50-60 percent. All other regular games seem fine with gpu usage almost always maxing out at 99/100 percent.

I don't see anything out of the ordinary tbh.

You might want to capture your headset's view directly, as any issues (such as lag) won't appear in the mirror usually. I'm not sure how you'd do that with oculus but with Vive/WMR it's as simple as using the OpenVR OBS plugin.

I've had that problem before, for me it was that something wasnt tracking correctly and lagging my headset (creating the distortion effect), I have a vive so for me it was just about updating the firmware for everything and redoing the room setup.
