boboweb No, it definitely wasn't like this on the Quest 2 until the latest update, at least for me anyway.
Some of the settings would affect the performance, like contrast, saturation or hue, while others would have no effect.
It may also have been to do with changing a few sliders, and eventually you get a performance drop, but I'm not sure, it always seemed totally random to me.
Except for sharpness, that never affected anything until now.
