It does not work with all games,for example.it crasges with grid autosport.
To have something similar install game booster plus from galaxy store, it is a plugin from samsung, open it via game launcher and install gos plus and perfz. With perfz you will be able to see fps, cpu and gpu usage and temp.
However i feel that polling time for fps are low so lag spike will not be registered and the temp is definitely underestimated...
