UI problems, standard workarounds not fixing it

Hey there.

I experience a lot of problems with the UI: Sometimes it's increaibly laggy, sometimes it's unresponsive, and every time I return to the campagin menu after play, the menu-UI doesn't return, and instead I see some leftover UI pieces from the gameplay, like the minimap and sins menu.

I've tried forcing the game and coherenceUI to use my high-performance driver and I've tried forcing it to run DX 9 and DX 11, as suggested by the knowledge base. Forcing any of the DX through the launch options helped a little, before that point I couldn't even get past the main menu, now I can start a game.

I'm not really sure what you need, but here are some of my system specs:
OS Name Microsoft Windows 10 Pro
Version 10.0.14393 Build 14393
System Manufacturer Notebook
System Model W65_67SJ
System Type x64-based PC
Processor Intel(R) Core(TM) i5-4210M CPU @ 2.60GHz, 2601 Mhz, 2 Core(s), 4 Logical Processor(s)
Installed Physical Memory (RAM) 8,00 GB
Total Physical Memory 7,89 GB
Available Physical Memory 4,31 GB
Total Virtual Memory 15,9 GB

I've forced both Coherent and WftO to use my Nvidia card, and since I am able to run the game, I'm pretty sure it's using it:
