Here's just an idea and possible theory, feel free to add on top with your own possibilities and ideas since this is just a basic idea that just popped up in my head.
first of all, the only way we're going to benefit from this is if we're already running a lower DPI, than our maximum allotted dpi available
So there was this issues with AUX mode profiles not being able to work, or just not having enough reliability.
my personally issue was that if I couldn't enter AUX with build button AND exit aux with build button, it just wasn't worth it and felt clunky.
Here is my idea,
let's say we're running 8000 DPI (out of 12,000)
and we'd wish to have a way to enter build mode and have our sensitivity raised up without much worry about reliability with syncing issues or different deactivation keys.
Why couldn't we set up 2 profiles on our mouse's on-board memory.
one with 8000 DPI
one with 12,000 DPI
and use the profile switch button as a build button that switches to 12k DPI whilst entering build mode through a simple macro that does both switch the profile to 12k dpi and presses the build button.
press it again to exit build mode and, go back to hip 8000dpi.
i'm horrible at explaining my ideas and I hope you guys understand.
Logitech g502 has a profile switch button and it allows macros to be used without the ximlink or titan 2.
I can't speak for other mice.
I just hope you can create a macro that brings up build mode and can switch a profile in one go.
just a thought. Thanks.
