Is 'vice' the right word for the subject?
Used as in rather than or as an alternative to, it has more brevity.

When upstreaming the gamezone WMI drivers the "extreme" mode was matched to performance and performance was matched to balanced-performance, but only when extreme mode was fully enabled. Otherwise performance was matched to performance. This has led to quite a bit of confusion with users not understanding why the LED color indicating the platform profile doesn't match their expectations. To solve this, replace the confusing convention with the new "extreme" profile.Are the colors common to all devices? Maybe it would be worth adding to the documentation the expected colors for each mode.
I think so, based on every case I've run into. I'll need to expound a little and reword more in this section but that should be doable. Thanks, Derek
