You mean if I run Destiny it will begin monitoring? I have run it and it seems that it isn't monitoring.You need to run some 3D application/game, only there it will start counting.
Riva Tuner, It is only picking up the FPS that seems to be recorded by "show own statistics".What is the FPS sensor in HWiNFO you're currently referring to? There are several ones - RTSS, FRAPS or AMD Vega (and later) GPU integrated FPS counters.
