You computer appears to be using the graphics of the R5 in the APU instead of the GTX 1050 Ti.
Did you connect your monitor to the GTX 1050 Ti?

Uninstall the Palit app and Download DDU
Start your PC in safe mode and run DDU to uninstall the Nvidia drivers.
After rebooting, allow Windows to install the drivers for your GPU.
Test and see if the FPS gets better or worse.
