PPSSPP bad OpenGL scaling on high resolution?

[pettry]

Hi,

I've recently purchased a Microsoft Surface Book.
And I Always loved being able to use ppsspp on the go.
But with the high resolution of the Surface Book(3000X2000) it seems that OpenGL can't get a steady frame rate, it usually is as low as 14-17.
DirectX solves the issue but then just like a hydra more issues pop up. When I'm using DirectX PPSSPP will crash upon loading ANY 3d geometry.

my test suite:
DBZ Shin Budokai 2(EU)
DBZ Tenkaich Tag Team(USA)
Final Fantasy Type-0(JAP-Patched)
Kingdom Hearts Birth by Sleep(JAP-Patched)

Specs:
I5-6300U(2.4-3.0 GHZ dual core and hypert hreading)
Unspecified Nvidia GPU(probably an Nvidia GT940MX)
8GB DDR3L 1866mhz

Software:
Windows 10 64-bit November build
