Stuttering and fps jumping in GoW games

[vsub_]

Any idea what is going on.
I decided to try the latest beta and tried to play the GoW games but the fps keeps jumping up and down and sometimes I don't get full speed for few seconds.

I am using the default settings and even tried setting the laptop cpu to be always at max Ghz and set the nvidia gpu at maximum performance but there was no difference at all(and yes,ppsspp is using the nvidia gpu not the igpu)

It's like it's slowing down every time the game tries to load something new(loading the game in ram also has no effect)

6700HQ,GTX1060,Win10 and plugged in(not on battery)...and the cpu\gpu are not overheating
