What AMD drivers are you using?
Do you not disable any GPU's in Device Manager. Please re-enable the device and uninstall your current drivers. You can download the latest Crimson 16.1.1 drivers here.
Head to Radeon Settings > Preferences > Additional Settings >
In CC Slim, navigate to Switchable Graphics Application Monitor and click start monitor. Use your laptop, browse the web, play some games. Go back and check to see which GPU is being used in the monitor report.
In CCC Slim, navigate to Switchable Graphics Application Settings. This area will allow you to select which 3D application uses the Integrated GPU or the High Performance GPU. Add the application to CCC and select High Performance Mode to ensure that the High Performance GPU is used. Note, it is recommend to have the laptop plugged in and Windows configured to High performance mode in the Control Panel > Power options to ensure you get the best possible performance.
The only available drivers that I can install is 15.12 Crimson
Anyway, I fixed my problem, I checked my battery option configuration and it's using my graphics by only "Optimize".
My FPS got higher after doing that.
Good to hear, glad it's working.
