BangBang This 72hz is a known issue and has nothing to do with Deovr. It is Meta throttling the hz because of heating issues with the Q3.
I dont want to be rude, but what kind of mushrooms you are all eating? This is not definitely true and sounds BS.
I have owned Quest 3 (with bigger memory) since the release and never heard this kind of fault. You could have always changed your refresh rate using DeoVR. Previously it was DeoVR fault not to achieve 120 hz if changed sharpening. Actually no matter what parameter you adjust it made Quest 3 fps to drop significant using DeoVR. But that was year or few ago.
Now DeoVR is almost in par with HereSphere considering video adjustment and fps. If you are using sharpening and passthrough, then 120 hz will actually lower fps compared to choose 90 hz. Sounds weird but that's how DeoVR works 🙂 Heresphere handles 120 hz and sharpening way better.
My Quest 3 version is 2.1.1034 and everything this topic contains sounds so weird for me. Never encountered that.
