Geforce 820m slower than intel integrated graphics (bay trail)

[solarmystic]

Have you verified that the 820m is reaching performance clocks when you're running PPSSPP?

I know you've already tried using MSI Afterburner to monitor the actual GPU usage whilst running the emulator, but what does it say about the actual clocks of the GPU? (Alternatively, you can try using GPUz to monitor the clocks and usage in real time too.)

According to notebookcheck.net, the peak clocks for the 820M in performance mode are as follows:-

Core Speed 775 MHz
Shader Speed 1550 MHz
Memory Speed 1800 MHz

There is no way that the Intel HD Graphics (Bay Trail) (which is basicallly a cutdown version of the Intel HD 4000 graphics chipset) should be surpassing the 820M in performance mode, which should be easily getting 100% speed in Tactics Ogre all the time with the default settings (2x Rendering Resolution). In fact, the performance of the 820M should rival that of the Intel Iris Graphics 5100 chipset.
