I like to have a custom quality settings option. But don’t remove the standard settings because they’re easy to use. Just add a custom one.
Especially for VR speed is very important and lot of times I need something between medium and high. I need the option to fine tune which option may be turned off to get a good performance and which one I need to get a good effect.
For example medium is good enough but mirrors looks complete fake/wrong because they only show the skybox. In that case medium is good but with the mirrors of high.
