I actually did get the Quest 3 haha. I didn't think the sharpen helped and actually made things worse, but maybe if I crank up the other settings it might be better instead.I also use HereSphere. I told you about the filters the first day, you have a bad memory, ha ha....
In the Advance Video Settings, try to change MSAA to 2 and Resolution to 1.1, 1.2, 1.3, etc, As far as your graphics card will let you.
In Basic Video Settings, move the Sharpen option to the right:
You can also zoom out, increases sharpness. With these options the definition of the videos is improved, if your graphics card can handle it.
But you didn't have Quest 3? What headset do you use?
