In the below screenshot you can clearly see the graphics card is in high perf instead of integrated. If I quit the sqlitebrowser app the mode will change to integrated immediately.

Interesting. Our application is built upon a cross platform framework called "Qt". My first thought is that maybe there's some setting(s) in Qt that would allow this. Maybe @revolter would know?

Maybe adding the
NSSupportsAutomaticGraphicsSwitchingInfo.plist key: https://codereview.qt-project.org/c/qt/qtbase/+/73839/.More details: https://stackoverflow.com/a/27211853/865175.
Are we using Qt 5.3+?

Qt v5.12.8, I believe.

@revolter Thanks heaps, that looks like the right kind of thing. 😄
And yep, Chris has it right. Our macOS and windows builds at the moment are using Qt 5.12.8.

#1935 looks like a related issue. Also, as @mgrojo says there, this might be related to #1233.

@ajaykumarmeher Would you be ok with trying something out?
If you could try adding this:
... to the file
/Applications/DB Browser for SQLite.app/Contents/Info.plist.It will need to be near the end, just after the
<true/>string before the</dict>one. Make a backup of the file first though, just in case. 😄In theory, once that change is done, you should be able to use the Integrated graphics card for the application.
If that does work, please let us know so we can add the change here for our future releases too. 😄

@justinclift thanks a lot for providing the fastest solution possible :) kudos to the team.
Tell Qt to allow use of an integrated graphics adapter

Awesome. I've just added that change to our source code, so it'll be in our nightly builds and all future releases too.
Thanks for looking into this @revolter, and thanks for testing it @ajaykumarmeher. 😄

Awesome 😄 I'll close this issue then.
